Faust (Functional Audio Stream) is a functional programming language for sound synthesis and audio processing with a strong focus on the design of synthesizers, musical instruments, audio effects, etc. created at the GRAME-CNCM Research Department . Faust targets high-performance signal processing applications and audio plug-ins for a variety of platforms and standards. The core component of Faust is its compiler. It allows to \"translate\" any Faust digital signal processing (DSP) specification to a wide range of non-domain specific languages such as C++, C, LLVM bit code, WebAssembly, Rust, etc. In this regard, Faust can be seen as an alternative to C++ but is much simpler and intuitive to learn. Thanks to a wrapping system called \"architectures,\" codes generated by Faust can be easily compiled into a wide variety of objects ranging from audio plug-ins to standalone applications or smartphone and web apps, etc. The Faust Web IDE Getting Started If You're in a Hurry If you\u2019re in a hurry and just wanna have a look at how Faust programs look like, you can simply check the Faust Examples .

It aimed at: giving an overview of the most recent developments in the Faust programming language, giving an introductory tutorial for those who never used Faust. Where is Faust Going as a Programming Language? -- Yann Orlarey Overview of Recent Developments in the Faust General Ecosystem -- St\u00e9phane Letz Faust and AI -- David Braun Faust in Real-Time Expressive Virtual Musical Instruments -- Julius O. Smith Real-Time Audio DSP With Faust and FPGAs -- Romain Michon Faust Physical Modeling Workshop Faust has been used for the physical modeling of musical instruments for many years now. Different tools have been developed recently to address the needs of various modeling techniques (e.g., finite difference scheme, waveguides, mass interaction, etc.). The goal of this one day online workshop which took place on Feb. 1, 2021 was to provide a series of interactive one-hour tutorials on these tools as well as some background on their related modeling techniques. Creating Circuit-Bendable Wave-Digital Models of Analog Audio Circuits in Faust -- Dirk Roosenburg Download this workshop's code here Wave-digital models are a well researched and popular approach for creating virtual-analog models of audio circuits for use in audio processing. wdmodels.lib is a new addition to the Faust Libraries that supports easy creation of these models in Faust. In this workshop, we will introduce the technique of wave-digital modeling of circuits by analyzing several audio circuits and exploring their implementation in wdmodels.lib . We also will discuss library support of more complex implementation tasks associated with wave-digital models, such as R-type adaptors and Multiple/Multiport non-linearities. Finally, we will conclude by exploring the capacity of Faust to \"circuit-bend\" our wave-digital models. Note : the workshop's code has been adapted to work with the latest version of the wdmodels.lib library embedded in the Faust Web IDE. You'll see some tiny syntax differences between the video and the new syntax. An Introduction to Mass-Interaction Modelling in Faust -- James Leonard and J\u00e9r\u00f4me Villeneuve Download this workshop's code here This workshop proposes an introduction to mass-interaction (sometimes referred to as mass-spring) modelling for sound synthesis in the Faust environment. After a brief historic introduction to this field, we will give a hands on tutorial on the mi_faust library, which allows simulating modular physical constructions in Faust, as well as online model scripting tools that allow for efficient model design and code generation. We will conclude with ongoing developments and perspectives, in particular regarding performance issues, possible extensions to 3-DoF physics, and the importance of modelling frameworks that allow for a creative approach to physical model design. Finite Difference Schemes Synthesis in Faust -- Riccardo Russo Download this workshop's code here Over the years, Faust proved to be a powerful tool for developing physical modeling synthesis. However, coding finite difference schemes models has always been complicated, in fact, their implementation in imperative programming languages is typically achieved using data structures, which are not available in Faust. This workshop will introduce the fds library, a new tool which allows to code linear, explicit finite difference schemes physical models in Faust, based on a cellular automata formalism. We will start with a brief introduction on how finite difference schemes work and what is their place within the scope physical modeling techniques. Then, we will focus on how to implement the algorithms we obtained on paper in Faust and, lastly, we will see how the fds library can be used to code such algorithms in a much easier way. By the end of the tutorial you should have quite an understanding on the basic principles of finite difference schemes, on the roles of the different functions inside the fds library and on how they can be used to easily obtain a working fds physical model. break Introduction to the Faust Physical Modeling Toolkit -- Romain Michon Download this workshop's code here A series of tools to facilitate the implementation of waveguide and modal physical models of musical instruments have been developed over the years by the Faust team to become the \"Faust Physical Modeling Toolkit.\" This comprises the Faust Physical Modeling library ( pm.lib ) as well as mesh2faust , a tool to convert 3D meshes into modal physical models compatible with pm.lib . During this workshop, we will provide a step-by-step tutorial on how to use these different tools to implement various kinds of physical models from scratch. Overview of Physical Modeling Formulations and Faust Implementations -- Julius O. Smith Download this workshop's code is available at https://ccrma.stanford.edu/~jos/aspf/Appendix_A_State_Space_Models.html#code:statespace and https://ccrma.stanford.edu/~jos/aspf/State_Space_BiQuad_FAUST.html#code:statespaceBiquad A summary of methods for physical modeling is followed by some examples in Faust. Physical models normally start out as differential equations which are then digitized to yield finite-difference schemes as were discussed earlier in this workshop. Wave digital and digital waveguide formulations were also discussed. Two additional topics are state-space models and modal representations which can be obtained by diagonalizing state-space models. As a result, this talk focuses primarily on state-space models and how to diagonalize them.","title":"Events"},{"location":"community/events/#events","text":"","title":"Events"},{"location":"community/events/#faust-day-2023","text":"Faust Day took place at the Center for Computer Research in Music and Acoustics (CCRMA) at Stanford University on May 20th, 2023.

WebAudio wasm benchmark pages and tools WebAudio wasm benchmark pages and tools allow to test statically generated HTML pages from Faust DSP. Audio generating pages in ScriptProcessor or AudioWorklet mode can be tested first. DSP CPU benchmark pages can be used to test the perfomance of wasm code across different browsers. Tools to generate new DSP CPU benchmark pages are also available, and finally a page allowing to test the dynamic compilation chain can be acccesed. Simple pages Simple pages can be used to test simple monophonic and polyphonic DSP, generated as ScriptProcessor or AudioWorklet WebAudio nodes. statically generated OSC as a ScriptProcessor node statically generated MIDI controllable Organ as a ScriptProcessor node Note that as 12/12/17, AudioWorklet pages can ony be tested with Chrome Canary. Be sure to activate AudioWorklet mode first. On a MacBook Pro OSX El Capitan 2,2 GHz Intel Core i7, we still hear audio glitches when testing them , for example when opening the JavaScript console, or interacting with other applications (like scrolling in the XCode editor, scrolling in the terminal...) statically generated OSC as an AudioWorlet node statically generated MIDI controllable Organ as an AudioWorlet node Polyphonic MIDI aware pages More complex statically generated polyphonic MIDI aware pages can be tested. ScriptProcessor based pages: modules/clarinetMIDI.html modules/elecGuitarMIDI.html modules/violinMIDI.html AudioWorklet based pages: modules-worklet/clarinetMIDI.html modules-worklet/elecGuitarMIDI.html modules-worklet/violinMIDI.html Benchmark pages A set of statically generated pages allow to measure the DSP CPU use of Faust generated WebAssemby code. The compute method is repeatedly called in a loop (taking 100% of a core) which duration is measured. Results as MBytes/sec as well a DSP CPU load in % of a 1024 frames, 44.1 kHz audio buffer are displayed. On the following pages, just hit the Start benchmark button, and wait for the result to be displayed. Note that since the computation is done in the main JavaScript thread, don't disturb your machine too much to get a reliable result. The pages can typically be used to compare the performances of different browsers: bench/clarinetMIDI.html bench/djembe.html bench/filterBank.html bench/freeverb.html bench/frenchBell.html bench/guitarEffectChain.html bench/karplus.html bench/karplus32.html bench/kisana.html bench/spectralLevel.html bench/stunedBar6.html bench/violinMIDI.html bench/zitaRev.html Testing the denormal issue A specific problem occurs when audio computation produces denormal float values, which is quite common with recursive filters, and can be extremely costly to compute on some processors like the Intel family for instance. Even with the software FTZ mode, we still see huge DSP CPU issue in some cases like this djembe physical model based on simple biquad filters: modules/djembe.html On OSX for instance, open the Activity Monitor tool and look as your browser CPU use. Then hit the checkbox to start playing, and hit it again to stop it. Silence should be produced, but actually very small sample values (= subnormals) are generated. If your machine uses an Intel CPU, you will see CPU raise quite rapidly ! (tested on a MacBook Pro OSX El Capitan 2,2 GHz Intel Core i7). Benchmark tools For developers, benchmark tools allow to generate HTML pages to test your DSP. Look in particular at the faust2benchwasm script. Dynamic compilation chain testing page A more complete testing page for monophonic and polyphonic MIDI aware DSP, ScriptProcessor or AudioWorklet mode, FTZ selection mode is available here . 2017-11-07: 1st IFC 1st International Faust Conference - Johannes Gutenberg University, Mainz (Germany), July 17-18, 2018 The International Faust Conference IFC-18 will take place at the Johannes Gutenberg University of Mainz (Germany) on July 17-18, 2018.

Contact Please, address your questions to: ifc18@muwiinfa.geschichte.uni-mainz.de Conference website: http://www.ifc18.uni-mainz.de 2017-10-20: New Editor New Faust Editor We are very happy to announce the online Faust Editor . It can be used to edit , compile and run Faust code from any recent Web Browser with WebAssembly support. This editor works completely on the client side and it is therefore very convenient for situations with many simultaneous users (workshops, classrooms, etc.). It embeds the latest version of the Faust compiler with an efficient WebAssembly backend and offers polyphonic MIDI support. Features The editor engine is based on codemirror . It offers syntax highlighting , auto completion and direct access to the online documentation . The documentation command (ctrl-d) uses the function name at the cursor position to locate to the relevant information. Recommended Browsers The recommended browsers are the latest versions of Firefox and Chrome. Chrome is recommended for MIDI, but it requires an https connexion to use the audio inputs. On the other hand MIDI is not supported by Firefox. Useful links Editor : the official link, https://grame-cncm.github.io/fausteditorweb/ : an alternative link on GitHub. Because this is an https address, audio inputs will work (but not the export function), https://github.com/grame-cncm/fausteditorweb : the GitHub repository. 2017-09-15: Performances... Performances of audio DSP code compiled in WebAssembly Porting and running large C/C++ code base on the Web have been the subject of several competing projects in the recent years, from Google NaCl/PNaCl to Mozilla asm.js . Recently standardized WebAssembly language inherits from ideas experimented in both approaches, with the Mozilla vision finnally winning as Robert O'Callahan explains here . Coupled with the WebAudio API , running real-time audio code in the Web now appears to be an achievable goal. WebAssembly is a hot topic in the JavaScript ecosystem. The WebAudio community is eagerly waiting for the AudioWorklet specification, with its promised reduced latency and glitch-free audio rendering, to land in browser development versions, and be tested. Porting well established C/C++ codebase with Emscripten , like the Csound framework as an example, or using DSL languages like Faust, will then naturally beneficiate from improved and more stable performances. The Faust ecosystem already allows to generate static or dynamically compiled WebAssembly based WebAudio nodes . These nodes are still using the deprecated ScriptProcessor WebAudio interface. Premillinary work has been started to be ready as soon at the AudioWorklet model will be testable. In the meantime, work have been started using the WAVM , a standalone VM for WebAssembly, that can load both the standard binary and text wasm format, compiling it in native code using the LLVM chain (generating LLVM IR and compiling it on the fly to native code using LLVM JIT compiler), and running it at (near) native speed. Glue code to load and run Faust generated wasm modules has been written. Validation and benchmarking tools have been developed. Performances comparison with the C++ and LLVM IR Faust backends is the subject of this post. Comparing the Faust C++, LLVM IR and wast/wasm backends The WebAssembly approach promises near native performances for C/C++ written code compiled to WebAssembly using the Emscripten tool chain. Other languages like Rust (using the mir2wasm tool) experiment direct WebAssembly generation. It seems clear that as WebAssembly specification and implementation stabilize, more and more languages will directly generate wasm to be deployed in browsers. The question of the quality of code generation at each step of the compilation chain will rapidly emerge. While WebAssembly is initially designed to run on the Web, it may be deployed in non Web environnement like nodejs , or even in standalone VM like WAVM . Thus WebAssembly becomes a portable binary format that can be used in a large variety of situations. This is especially of interest for a DSL language like Faust. Faust wast/wasm backend Faust wast/wasm backend directly produce WebAssembly code from the Faust internal FIR (Faust Imperative Representation) code. Generated modules are rather light since they define a very simple ABI to be used by the loader code. Two generation models have been defined: in monophonic mode the wast/mast module internally allocates a memory block to be used for the DSP state (controllers, delays lines, waveforms...) as well as audio buffers. in polyphonic mode, the memory block will be allocated by the loader environnement. This block will typically be sized to contain all the needed voices for the polyphonic DSP. In both cases, a full description of the DSP state as a JSON string is generated in the module data segment (including memory indexes of all controllers). Loader code will get and decode this JSON description, and use whatever parts of the description it needs to run the DSP code. In particular, control memory zones (corresponding to the UI items like buttons, sliders, bargraph...) can be directly read/written by the wrapper code. Benchmark of C++, LLVM IR and wast/wasm generated code Since Faust already generates C++ or LLVM IR code, the performances of those two backends can be compared with the new wasm one. Using the WAVM C++ written machine allows to deploy the same measuring code . The first benchmark compares the speed of C++, LLVM IR and wasm backends running a set of DSP, running on a MacBook Pro 2,2 GHz Core I7 with OSX El capitan. The same 4.0 version of LLVM toolchain has been used with the three backend. C++ and LLVM IR code has been compiled with the -Ofast optimization flag, the WAVM runtime is the standard version one (without any specific audio optimization, see later): The diagrams clearly shows that the wasm code is still slower than C++ or LLVM IR code, but speed difference is not so high in most cases. Some DSP behaviours need to be understood in more details. Optimizing the WAVM runtime for audio code The WAVM runtime strictly conforms to the WebAssembly specification, thus behaving as a interesting base reference. In the audio domain, the deployed code is usually compiled with specific optimization flags. Since C++ WAVM runtime can be hacked quite easily, we did several changes into the reference implementation to gain some speed: removing the atomic flag in all load/store that are added to pass all spec WebAssembly tests. adding the equivalent of -fast-math compilation flag that have to be done at LLVM IR and JIT (= native) generation steps. and finally simplifying some mathematical operators, using their standard definition instead of the specific WAVM coded ones that strictly implement WebAssembly official semantic (see for instance the definition of f32.min/f32.max operations). Here is the diagram of DSP examples run with reference WAVM runtime, and the three specific optimizations: After generating the LLVM IR code, the WAVM runtime runs a set of LLVM IR to IR optimizations passes. It remains to be tested if adding more optimization passes (especially the auto-vectorizations ones) could help producing even better code. WebAssembly module optimization with Binaryen Binaryen is a compiler and toolchain infrastructure library for WebAssembly , written in C++. We tested the wasm-opt tool at -O3 level on Faust generated wasm modules to estimate which speedup we can expect. The following diagram shows limited gains, with no more than 5% in some of the tested cases: Float denormal handling A specific problem occurs when audio computation produces denormal float values, which is quite common with recursive filters, and can be extremely costly to compute on some processors like the Intel family for instance. A Flush To Zero (FTZ) mode for denormals can usually be set at hardware level, but it not yet available in the WebAssembly MVP version, which strictly conform to the IEEE 754 norm 8. Thus an automatic software strategy which consists in adding FTZ code in all recursive loops has been implemented in the Faust compiler. To activate it, the -ftz compilation parameter must be used at compilation time. The -ftz 1 mode adds a test in each recursive loop which uses the fabs function and a threshold to detect subnormal samples (slower). The -ftz 2 mode adds a test in each recursive loop which uses a mask to detect subnormal samples (faster). Even if using software ftz is not strictly needed in our benchmark chain (since the C++ WAVM uses the ftz hardware protection mode), we can still compare the speed of the different ftz options. Here is the result of code generated with -ftz from 0 to 2: Comparing three browsers on OSX El Capitan HTML test pages were prepared to compare the performances of the three main browsers on OSX El Capitan. The DSP code is compiled with float denormal protection on (-ftz 2). The generated wasm module compute method is called repeatedly in a timed loop, using successive slices of a big allocated circular audio buffer to avoid cache effects. Here are the results: The fasted one (Chrome for now) can be compared with C++, LLVM IR, WAVM native engines, all compiled with float denormal protection on (-ftz 2): Comments and Conclusion Testing wasm JIT machines inside browsers is not an easy task. The C++ WAVM runtime revealed to be an excellent tool to compare the Faust C++, LLVM IR and wasm backend. Since its code can be easily adapted, one can estimate also what can be expected deploying wasm DSP modules in pure native environments , outside of the browser, where some audio specific optimizations may be considered. Measures done on a set of Faust DSP show that WebAssembly code still run slower than C++ or LLVM IR generated code in most cases, up to almost 66% slower in the less favorable examples. This value will typically be a bit worse when deploying in browsers, since float denormal protection code has to be used . Benchmarks in browser wasm runtime still need to be done to confirm or refine these findings. Comparing the Chrome , Firefox and WebKit browsers on OSX El Capitan shows that Chrome is currently the fastest engine in most cases, with Firefox and WebKit quite similar (with a slight plus for WebKit). Comparing the Chrome browser with native engines shows results from 4,8 times slower (filterBank.dsp), 2,8 times slower (sTunedBar6.dsp) up to much more favorable cases (karplus32.dsp). Note that filterBank.dsp example is a bit of a pathological case, since Chrome is significantly slower than Firefox and WebKit in this case, and filterBank.dsp uses a lot of pow(10, x) code that is rewritten an optimized as exp10(x) with the C++ backend path. 2017-08-18: Faust on the Web Deploying Faust DSP on the Web EDIT : we are at the Web Audio conference 2017, and it appears that the way we currently extend the ScripProcessorNode with Faust code is not the Right Way... Part of the post concerning the exposed API will probably change a bit in the near future... Using latest developments done for the Web (the new WebAssembly backends and libfaust library compiled in WebAssembly with Emscripten), statically and dynamically Faust generated WebAudio nodes can be easily produced and deployed on the Web. Deploying statically compiled Faust WebAudio nodes From a foo.dsp source file, JavaScript and the associated WebAssembly files can be produced with the following script: faust2wasm foo.dsp This will generate a foo.wasm file with the WebAssembly module as binary code, as well as a foo.js wrapper file containing the code needed to turn the Faust DSP in a fully working WebAudio node (using an extended ScriptProcessor node). The name of the Faust DSP code file is used to define the final ScriptProcessorNode constructor name. So for instance if osc.dsp file is compiled, the following faust.createosc function will be generated: /** * Create a 'monophonic' ScriptProcessorNode Web Audio object * by loading and compiling the Faust wasm file * * @param context - the Web Audio context * @param buffer_size - the buffer_size in frames * @param callback - a callback taking the created ScriptProcessorNode as parameter, * or null in case of error */ faust.createosc = function(context, buffer_size, callback) The resulting object is an extended ScriptProcessorNode, to be used as a regular node (like connected to other WebAudio nodes), but which also adds the Faust specific API as defined in the equivalent C++ generated dsp class (see the architecture/faust/dsp/dsp.h header for more technical details), as well as JavaScript more specific functions. For instance the following ones will have to be used to control the node: var paths = node.getParams(); // get the set of paths to read/write input control parameters Then knowing the path for a given parameter, the following function is used to change the parameter value: node.setParamValue(\"/Oscillator/freq\", 0.6); A full JSON description of the node with the complete UI, can be retrieved with: var json = node.getJSON(); The complete usable API is fully documented in the generated JavaScript file in the Public API to be used to control the WebAudio node section. A simple example Web page A simple Web page using the files generated by faust2wasm on the noise.dsp file can be defined with the following parts: <!-- Load 'faust2wasm' script generated .js file --> <script src=\"noise.js\"></script> A slider to control the noise volume parameter is defined with: <P> Noise volume: <input type=\"range\" oninput=\"changeVolume(event) \"min=\"0\" max=\"1\" value=\"0.5\" step=\"0.01\"/> The WebAudio context is created and the noise slide hander is defined with: var isWebKitAudio = (typeof (webkitAudioContext) !== \"undefined\"); var audio_context = (isWebKitAudio) ? new webkitAudioContext() : new AudioContext(); var noise = null; // Slider handler to change the 'noise' volume function changeVolume(event) { noise.setParamValue(\"/Noise/Volume\", parseFloat(event.target.value)); } A startnoise function which creates the Faust WebAudio node is defined with: function startnoise() { // Create the Faust generated node faust.createnoise(audio_context, 1024, function (node) { noise = node; console.log(noise.getJSON()); // Print paths to be used with 'setParamValue' console.log(noise.getParams()); // Connect it to output as a regular WebAudio node noise.connect(audio_context.destination); }); } An finally the load handler is defined to activate the code: window.addEventListener(\"load\", startnoise); Look at the Noise and OSC online pages for the complete code. Note that pages loading an additional .wasm file cannot directly be loaded in Chrome. You'll have to start a local server (using the python -m SimpleHTTPServer command for instance) and access them with their http:// based URL. Generating Polyphonic WebAudio nodes Assuming that the compiled Faust DSP file is polyphonic ready , a polyphonic ready WebAudio node can be created with the -poly parameter, and will generate the following constructor for the node (where the mydsp part will be replaced by the actual DSP name): /** * Create a 'polyphonic' ScriptProcessorNode Web Audio object * by loading and compiling the Faust wasm file * to be use for the voice, and allocating the number of needed voices * * @param context - the Web Audio context * @param buffer_size - the buffer_size in frames * @param polyphony - the number of polyphonic voices * @param callback - a callback taking the created ScriptProcessorNode * as parameter, or null in case of error */ faust.createmydsp_poly = function(context, buffer_size, polyphony, callback) Polyphonic nodes have an extended API to be controled with MIDI messages: /** * Instantiates a new polyphonic voice. * * @param channel - the MIDI channel (0..15, not used for now) * @param pitch - the MIDI pitch (0..127) * @param velocity - the MIDI velocity (0..127) */ keyOn = function (channel, pitch, velocity) /** * De-instantiates a polyphonic voice. * * @param channel - the MIDI channel (0..15, not used for now) * @param pitch - the MIDI pitch (0..127) * @param velocity - the MIDI velocity (0..127) */ keyOff = function (channel, pitch, velocity) /** * Gently terminates all the active voices. */ allNotesOff = function () Look at the JavaScript public documentation section for the complete description. Extended control with -comb parameter The faust2wasm tool can be used with the -comb parameter to compile several DSP files and contatenate all JavaScript code in a unique resulting comb.js file (possibly to be used in -poly mode also). Generating fully working self-contained HTML pages The faust2webaudiowasm script can be used to generate a fully working self-contained HTML page, with a SVG/CSS a Graphical User Interface. From the osc.dsp Faust DSP source file, it will generate an osc.html file: faust2webaudiowasm osc.dsp Assuming that the compiled Faust DSP file is polyphonic ready, the -poly parameter can be used to generate a polyphonic MIDI controlable instrument, to be used with a MIDI application or device. The -links generates the DSP processor SVG representation, and links to the original DSP file as well as generated SVG files, so that the HTML page can possibly be deployed as a reusable Faust DSP resource. WebAssembly module optimization Assuming that you have Binaryen tools installed on your machine, the faust2wasm and faust2webaudiowasm scripts can take an additional -opt parameter to allow WebAssembly module optimization. Deploying dynamically compiled Faust WebAudio nodes Since the libfaust library is available for the Web, it becomes possible to embed the complete dynamic compilation chain in a Web page , from the Faust DSP source to the executable WebAudio node. First the following resources (located on the Faust GitHub in architecture/webaudio folder) have to be loaded in the page: <!-- Load 'libfaust' library and wrapper code --> <script src=\"libfaust-wasm.js\"></script> <script src=\"webaudio-wasm-wrapper.js\"></script> Then the two following functions are used to generate factories, creating later on monophonic or polyphonic instances (this is necessary because of the way internal WebAssembly memory is managed): /** * Create a DSP factory from source code as a string to be used to create monophonic DSP * * @param code - the source code as a string * @param argv - an array of parameters to be given to the Faust compiler * @param callback - a callback taking the created DSP factory as parameter, * or null in case of error */ faust.createDSPFactory = function (code, argv, callback) /** * Create a DSP factory from source code as a string to be used to create polyphonic DSP * * @param code - the source code as a string * @param argv - an array of parameters to be given to the Faust compiler * @param callback - a callback taking the created DSP factory as parameter, * or null in case of error */ faust.createPolyDSPFactory = function (code, argv, callback) The two following functions are used to generate monophonic or polyphonic Faust WebAudio nodes: /** * Create a ScriptProcessorNode Web Audio object from a factory * * @param factory - the DSP factory * @param context - the Web Audio context * @param buffer_size - the buffer_size in frames * @param callback - a callback taking the created ScriptProcessorNode as parameter, * or null in case of error */ faust.createDSPInstance = function (factory, context, buffer_size, callback) /** * Create a 'polyphonic' 'ScriptProcessorNode Web Audio object from a factory * * @param factory - the DSP factory * @param context - the Web Audio context * @param buffer_size - the buffer_size in frames * @param polyphony - the number of polyphonic voices * @param callback - a callback taking the created ScriptProcessorNode as parameter, * or null in case of error */ faust.createPolyDSPInstance = function (factory, context, buffer_size, polyphony, callback) The resulting nodes have the same API as statically compiled nodes described in the first section, so can be controlled the same way, including the polyphonic ones. Here is a code example using faust.createDSPFactory and faust.createDSPInstance : var isWebKitAudio = (typeof (webkitAudioContext) !== \"undefined\"); var audio_context = (isWebKitAudio) ? new webkitAudioContext() : new AudioContext(); var dsp_code = \"import(\\\"stdfaust.lib\\\"); vol = hslider(\\\"volume [unit:dB]\\\", 0, -96, 0, 0.1) : ba.db2linear : si.smoo; freq = hslider(\\\"freq [unit:Hz]\\\", 1000, 20, 24000, 1); process = vgroup(\\\"Oscillator\\\", os.osc(freq) * vol);\"; var osc = null; var libraries_url = \"/modules/libraries/\"; function startosc() { // Prepare argv list var argv = []; argv.push(\"-ftz\"); argv.push(\"2\"); argv.push(\"-I\"); argv.push(libraries_url); // Dynamically create the Faust generated node from explicit DSP source in 'dsp_code' faust.createDSPFactory(dsp_code, argv, function (factory) { faust.createDSPInstance(factory, audio_context, 1024 function (node) { osc = node; console.log(osc.getJSON()); // Print paths to be used with 'setParamValue' console.log(osc.getParams()); // Connect it to output as a regular WebAudio node osc.connect(audio_context.destination); })}); } The Dynamic OSC page demonstrates the dynamic OSC complete code (based on the example seen before). The Dynamic Organ page demonstrates a polyphonic organ instrument, which loads a DSP from an url, and ready to be controlled with a MIDI device or application. Look at the Dynamic Faust compiler page for a more complete use-case of the dynamic compiler. Float denormal handling A specific problem occurs when audio computation produces denormal float values, which is quite common with recursive filters, and can be extremely costly to compute on some processors like the Intel family for instance. A Flush To Zero (FTZ) mode for denormals can usually be set at hardware level, but it not yet available in the WebAssembly MVP version, which strictly conform to the IEEE 754 norm 8. Thus an automatic software strategy which consists in adding FTZ code in all recursive loops has been implemented in the Faust compiler. To activate it, the -ftz compilation parameter must be used at compilation time. The -ftz 1 mode adds a test in each recursive loop which uses the fabs function and a threshold to detect subnormal samples (slower). The -ftz 2 mode adds a test in each recursive loop which uses a mask to detect subnormal samples (faster). Use for example the following line to active software denormal handing when using faust2wasm tool: faust2wasm -ftz 2 foo.dsp The same for the faust2webaudiowasm tool: faust2webaudiowasm -ftz 2 foo.dsp For dynamic compilation, the -ftz v flag will have to be added in the argv parameter in faust.createDSPFactory or faust.createPolyDSPFactory , like for instance: faust.createPolyFactory(dsp_code, ['-ftz', '2'], callback); 2017-06-16: Memory allocator Using a custom memory allocator From a DSP source file, the Faust compiler typically generates a C++ class. When a rdtable item is used on the source code, the C++ class will contain a table shared by all instances of the class. By default, this table is generated as a static class array, and so allocated in the application global static memory. In some specific case (usually in more constrained deployment cases), managing where this data is allocated is crucial. By extension this post explains how a custom memory allocator can be used to precisely control the DSP memory allocation. Faust -mem option to control memory related code generation A new -mem compiler parameter has been added in the Faust compiler, starting from the 0.9.103 version (or 2.1.4 in Faust2 branch). This parameter will change the way static shared tables are generated. The table is allocated as a class static pointer allocated using a custom memory allocator , which has the following propotype: struct dsp_memory_manager { virtual ~dsp_memory_manager() {} virtual void* allocate(size_t size) = 0; virtual void destroy(void* ptr) = 0; }; Taking the following Faust DSP example: process = (waveform {10,20,30,40,50,60,70}, %(7)~+(3) : rdtable), (waveform {1.1,2.2,3.3,4.4,5.5,6.6,7.7}, %(7)~+(3) : rdtable); Here is the generated code in default mode: ... int mydsp::itbl0[7]; float mydsp::ftbl0[7]; static void classInit(int samplingFreq) { SIG0 sig0; sig0.init(samplingFreq); sig0.fill(7,itbl0); SIG1 sig1; sig1.init(samplingFreq); sig1.fill(7,ftbl0); } virtual void init(int samplingFreq) { classInit(samplingFreq); instanceInit(samplingFreq); } virtual void instanceInit(int samplingFreq) { instanceConstants(samplingFreq); instanceResetUserInterface(); instanceClear(); } ... The two itbl0 and ftbl0 tables are static class arrays. They are filled in the classInit method. The architecture code will typically call the init method (which calls classInit ) on a given DSP, to allocate class related arrays and the DSP itself. If several DSP are going to be allocated, calling classInit only once then the instanceInit method on each allocated DSP is the way to go. In the new -mem mode, the generated C++ code is now: ... int* mydsp::itbl0 = 0; float* mydsp::ftbl0 = 0; dsp_memory_manager* mydsp::fManager = 0; static void classInit(int samplingFreq) { SIG0 sig0; itbl0 = static_cast<int*>(fManager->allocate(sizeof(int) * 7)); sig0.init(samplingFreq); sig0.fill(7,itbl0); SIG1 sig1; ftbl0 = static_cast<float*>(fManager->allocate(sizeof(float) * 7)); sig1.init(samplingFreq); sig1.fill(7,ftbl0); } static void classDestroy() { fManager->destroy(itbl0); fManager->destroy(ftbl0); } virtual void init(int samplingFreq) {} virtual void instanceInit(int samplingFreq) { instanceConstants(samplingFreq); instanceResetUserInterface(); instanceClear(); } ... The two itbl0 and ftbl0 tables are generated a class static pointers. The classInit method takes the additional dsp_memory_manager object used to allocate tables. A new classDestroy method is available to deallocate the tables. Finally the init method is now empty, since the architecure file is supposed to use the classInit/classDestroy method once to allocate and deallocate static tables, and the instanceInit method on each allocated DSP. Control of the DSP memory allocation An architecture file can now define its custom memory manager by subclassing the dsp_memory_manager abstract base class, and implement the two required allocate and destroy methods. Here is an example of a simple heap allocating manager: struct malloc_memory_manager : public dsp_memory_manager { virtual void* allocate(size_t size) { void* res = malloc(size); cout << \"malloc_manager: \" << size << endl; return res; } virtual void destroy(void* ptr) { cout << \"free_manager\" << endl; free(ptr); } }; Controlling the table memory allocation To control table memory allocation, the architecture file will have to do: // Allocate a custom memory allocator malloc_memory_manager manager; // Setup manager for the class mydsp::fManager = &manager; // Allocate the dsp instance using regular C++ new mydsp* dsp = new mydsp(); // Allocate static tables (using the custom memory allocator) mydsp::classInit(48000); // Initialise the given instance dsp->instanceInit(48000); ... ... // Deallocate the dsp instance using regular C++ delete delete dsp; // Deallocate static tables (using the custom memory allocator) mydsp::classDestroy(); Controlling the complete DSP memory allocation Full control the DSP memory allocation can be done using C++ placement new : #include <new> // Allocate a custom memory allocator malloc_memory_manager manager; // Setup manager for the class mydsp::fManager = &manager; // Placement new using the custom allocator mydsp* dsp = new(manager.allocate(sizeof(mydsp))) mydsp(); // Allocate static tables (using the custom memory allocator) mydsp::classInit(48000); // Initialise the given instance dsp->instanceInit(48000); ... ... // Calling the destructor dsp->~mydsp(); // Deallocate the pointer itself using the custom memory allocator manager.destroy(dsp); // Deallocate static tables (using the custom memory allocator) mydsp::classDestroy(); More complex custom memory allocators can be developed by refining this malloc_memory_manager example, possibly defining real-time memory allocators...etc... The OWL architecture file already uses this new custom memory allocator model. This is a work in progress: in the Faust2 branch, this model is still not supported yet beside the C++ backend custom memory allocator is not yet supported is additional DSP classes (like the mydsp_poly defined in the achitecture/faust/dsp/poly-dsp.h header). 2017-04-26: Optimizing... Optimizing the DSP CPU usage The Faust compiler has as lot of different compilation parameters to play with. Discovering them for a given DSP program is something that can be automated. Two measure_dsp and dsp_optimizer classes are available for developers to measure DSP CPU use directly in their code. Two more friendly faustbench and faustbench-llvm tools have been developed using them. They allow to discover the best Faust compiler parameters, to be used later on with faust2xx scripts, faustgen~ Max/MSP external or FaustLive . The measure_dsp and dsp_optimizer DSP decorator classes The measure_dsp class defined in the faust/dsp/dsp-bench.h file allows to decorate a given DSP object and measure its compute method CPU consumption. Results are given in Megabytes/seconds (higher is better). Here is a C++ code example of its use: static void bench(dsp* dsp, const string& name) { // Init the DSP dsp->init(48000); // Wraps it with a 'measure_dsp' decorator measure_dsp mes(dsp, 1024, 5); // Measure the CPU use mes.measure(); // Print the stats cout << name << \" CPU use : \" << mes.getStats() << endl; } Only part of the Faust2 branch and defined in the faust/dsp/dsp-optimizer.h file, the dsp_optimizer class uses the libfaust library and its LLVM backend to dynamically compile DSP objects produced with different Faust compiler options, and then measure their DSP CPU. Here is a C++ code example of its use: static void dynamic_bench(const string& dsp_source) { // Init the DSP optimizer with the dsp_source to compile // (either the filename or source code string) dsp_optimizer optimizer(dsp_source, \"/usr/local/share/faust\", \"\", 1024); double value; // Discover the best set of parameters vector<string> options = optimizer.findOptimizedParameters(value); // Print the result cout << \"Best value is for '\" << argv[1] << \"' is : \" << value << \" with \"; for (int i = 0; i < options.size(); i++) { cout << options[i] << \" \"; } cout << endl; } Using the faustbench tool The faustbench tool uses the C++ backend to generate a set of C++ files produced with different Faust compiler options. All files are then compiled in a unique binary that will measure DSP CPU of all versions of the compiled DSP. The tool is supposed to be launched in a terminal, but it can be used to generate an iOS project, ready to be launched and tested in Xcode. Here are the available options: faustbench [-ios] [Additional Faust options (-vec -vs 8...)] <file.dsp> Use '-ios' to generate an iOS project Use 'export CXX=/path/to/compiler' before running faustbench to change the C++ compiler Use 'export CXXFLAGS=options' before running faustbench to change the C++ compiler options Here is a trace of its use: faustbench karplus32.dsp Selected compiler is g++ with CXXFLAGS = -Ofast -scal : 77.5123 -vec -lv 0 -vs 4 : 64.2194 -vec -lv 0 -vs 8 : 80.8951 -vec -lv 0 -vs 16 : 106.244 ..... -vec -lv 1 -vs 128 -g : 130.635 -vec -lv 1 -vs 256 -g : 134.335 -vec -lv 1 -vs 512 -g : 135.352 Best value is : 136.235 with -vec -lv 0 -vs 512 Using the faustbench-llvm tool Available in the faust2 branch only, the faustbench-llvm tool uses the libfaust library and its LLVM backend to dynamically compile DSP objects produced with different Faust compiler options, and then measure their DSP CPU. In the main Faust folder, use make bench && sudo make install to build and install the tool. Here is a trace of its use: faustbench-llvm karplus32.dsp Estimate timing parameters -scal : 21.1269 duration = 0.102801 count = 24318 Discover best parameters option -scal : 21.1034 -vec -lv 0 -vs 4 : 42.0734 -vec -lv 0 -vs 8 : 55.3725 -vec -lv 0 -vs 16 : 85.3855 ..... -vec -lv 1 -vs 128 -dfs : 133.974 -vec -lv 1 -vs 256 -dfs : 139.12 -vec -lv 1 -vs 512 -dfs : 91.8424 Refined with -mcd -vec -lv 0 -vs 256 -g -mcd 2 : 83.5555 -vec -lv 0 -vs 256 -g -mcd 4 : 138.519 -vec -lv 0 -vs 256 -g -mcd 8 : 140.122 -vec -lv 0 -vs 256 -g -mcd 16 : 141.558 -vec -lv 0 -vs 256 -g -mcd 32 : 139.454 -vec -lv 0 -vs 256 -g -mcd 64 : 143.405 -vec -lv 0 -vs 256 -g -mcd 128 : 142.975 -vec -lv 0 -vs 256 -g -mcd 256 : 139.345 Best value is for 'karplus32.dsp' is : 142.473 with -vec -lv 0 -vs 256 -dfs -mcd 64 w 2017-02-21: Faust meets JUCE JUCE is an open-source cross-platform C++ application framework, used for the development of desktop and mobile applications. JUCE is used in particular for its GUI and plugins libraries. A set of architecture files have been developed to deploy standalone or plugins built from Faust code. They allow to automatically generate the GUI from the Faust program, possibly supporting polyphonic instruments, and be controlled by MIDI or OSC messages. The architecture files are then combined to produce ready to compile JUCE applications or plugins, using tools that are part of the Faust distribution. They can also be accessed using the Faust online compiler. faust2juce script faust2juce transforms a Faust DSP program into a fully working JUCE standalone application or plugin, which can possibly be controlled with MIDI or OSC messages. Read its complete description here . You'll have to get a recent github version of Faust tree to use it. Using the online compiler The Faust online compiler has been updated to provide new 'juce' targets. Note that only some of the possible compilation options are availble for now: the application target produces a standalone MIDI controlable application (using Faust polyphonic code if the Faust source code is polyphonic aware) the plug-in target produces a MIDI controlable mono or polyphonic plugin (using Faust polyphonic code if the Faust source code is polyphonic aware) the jsynth target produces a MIDI controlable mono or polyphonic plugin (using JUCE polyphonic Synthesizer if the Faust source code is polyphonic aware) Directly using faust2juce provides the full control of the generated target with access to all possible compilation parameters. Graph of Faust generated plugins Here is an example of three Faust generated plugins running in JUCE plugin host: Using libfaust and LLVM An alternative to faust2juce static-compilation model, is to use Oliver Larkin's juce_faustllvm module, also used in his pMix2 tool . 2017-01-13: WebAssembly... Faust WebAssembly backend WebAssembly was born with the premise of creating a safe, portable and fast to load and execute format suitable for the web. WebAssembly its not a programing language but a compilation target with a text and binary specs. That means that other low level languages like C/C++, Rust, Swift, etc. can compile to WebAssembly. Specified and developed by principal browser compagnies (Google, Mozilla, Microsoft and Apple), this new format aims to finally replace the more hackish \"asm.js\" format initialy developed by Mozilla. Development versions of Chrome and Firefox can already execute it. To get an early preview of this experimental technology, at your own risk: on Chrome Canary , open chrome://flags/#enable-webassembly and enable the switch on Firefox Nightly , open about:config and set javascript.options.wasm to true See a preview of Microsoft Edge support and follow Safari support on WebKit\u2019s feature status . WebAssembly backends New WebAssembly backends have been added in the faust2 development branch. They allow to generate textual or binary WebAssembly code. 'wast' textual backend The 'wast' backend allows to generate textual WebAssembly code (in s-expression like format). Note that as of january 2017, the official textual format is not yet fully specified, thus we follow the format used in the binaryen tool . Use the following command to generate the textual output in the terminal for a given foo.dsp file. faust -lang wast foo.dsp The following command: faust -lang wast foo.dsp -o foo.wast will generate the foo.wast textual WebAssembly output file as well as an additional foo.js JavaScript file containing glue code. 'wasm' binary backend The 'wasm' backend allows to generate binary WebAssembly code. Use the following command to generate the binary output in the terminal for a given foo.dsp file. faust -lang wasm foo.dsp The following command: faust -lang wasm foo.dsp -o foo.wasm will generate the foo.wast binary WebAssembly output file as well as an additional foo.js JavaScript file containing glue code. Generating static HTML pages WebAssembly code can be feeded into WebAudio JavaScript nodes, which can then be used like any other native WebAudio node. Two scripts are available to generate static WebAudio html pages from a given foo.dsp source file with the generated html/css/svg user interface: faust2webaudiowast foo.dsp will generate the textual WebAssembly output, use binaryen wasm-as tool to convert the wast to wasm format (you'll have to compile and install the binaryen tools on your machine), and produce a self-contained html page. faust2webaudiowasm foo.dsp will generate the binary WebAssembly output that can directly be loaded by the produced self-contained html page. Page containing polyphonic instruments can be generated with the following commands: faust2webaudiowast -poly foo.dsp to use the 'wast' backend and a polyphonic ready foo.dsp, and create a self-contained html page ready to be used with a MIDI instrument. faust2webaudiowasm -poly foo.dsp to use the 'wasm' backend and a polyphonic ready foo.dsp, and create a self-contained html page ready to be used with a MIDI instrument. 2016-10-17: Faust Award 2016 The Faust Open Source Software Competition aims at promoting innovative high-quality free audio software developed with Faust, a functional programming language for realtime signal processing and sound synthesis. The competition is sponsored by GRAME , Centre National de Cr\u00e9ation Musicale Faust Award 2016 to Ambitools The Faust Award 2016 was attributed by an international committee composed of : Jean-Louis Giavitto (IRCAM, Paris, France), Albert Graef (Johannes Gutenberg U., Mainz, Germany), Pierre Jouvelot (Ecole des Mines, Paris, France), Victor Lazzarini (Maynooth U., Maynooth, Ireland), Romain Michon (Stanford U., Palo Alto, USA) Yann Orlarey (GRAME, Lyon, France), Dave Phillips (musician, journalist, and educator, USA) Laurent Pottier (U. Jean Monnet, Saint-Etienne, France), Julius Smith (Stanford U., Palo Alto, USA) to Ambitools , a set of tools for real-time 3D sound field synthesis using higher order ambisonics (HOA). Ambitools is developed by Pierre Lecomte, a PhD candidate at Conservatoire National des Arts et M\u00e9tiers and Sherbrooke University. The core of the sound processing is written in Faust. The tools contain HOA encoders, decoders, binaural-filters, HOA signals transformations, spherical VU-Meter, etc. and can be compiled in various plug-ins format under Windows, Mac OSX, and Linux. The jury praised the quality and the usefulness of Ambitools: a really useful and technically advanced Faust app and an impressive technical achievement ! Check the demo . The committee was also very impressed by the quality of two other projects : Voice of Faust , a voice synthesizer/effects machine by Bart Brouns ( demo ). PMix , a graphical patcher, preset interpolator and JIT compiler for FAUST by Oliver Larkin ( demo ). Faust Student Software Competition to TouchVoices In parallel to the main competition, we introduced this year a junior competition: the Faust Student Software Competition , intended to promote small but interesting Faust applications, typically written as student projects. The student prize was awarded to TouchVoices (by Pierre-Adrien Th\u00e9o, RIM Master student at University Jean Monnet) a real-time web application allowing to capture, playback and transform sound loops. Here is a video of Pierre-Adrien Th\u00e9o during a performance with TouchVoices . A very close competitor was SuperBeatRepeater (by Vincent Rateau, of SuperDirt fame), a sample accurate beat repeater. Don't miss the demo ! 2016-08-30: FAUST book... The first FAUST book is Korean ! \u201c Sound Programming using FAUST \u201d, written by Jin-Wook Chae , an experienced audio developer and sound engineer (right) and Hyun-Hoo Jung (left), is the very first book ever published on FAUST. While the book is written in Korean, I was able to really appreciate the choice of the examples and the elegance as well as the high quality of the code. I am sure it will be an invaluable tool to promote FAUST in Korea among sound engineering, computer music students and more generally any person interested in sound programming. This book is for people desiring to produce musical instruments or sound processors. I have always been instructing my students that the ultimate importance is to discover interesting ideas about the sound. In spite of that, I have often relied on an unflattering response such as \"you may need to learn a programming language like C/C++...\" when a student asked for help with how to execute his/her ideas related to sound. Now I am pleased to recommend the use of FAUST to bring such ideas into execution. This is an easy self-study guide that can help to do just that. Now I can confidently tell anybody pursuing sound or electronic music that their exciting and brilliant idea about sound is what truly counts! So, really, how do we execute our ideas? Today I am introducing you to FAUST and to this book which you will find immensely helpful in terms of how to use FAUST to bring your fabulous ideas into reality. Jinwook Chae 2016-06-30: Faust interpreter A new 'interpreter' backend has been added in the faust2 development branch. It allows to execute Faust programs without using the LLVM dynamic compiler chain. Interpreter compilation chain The dynamic compilation chain allows developers to embed the Faust compiler technology directly in their application or plugins. Faust2 development branch uses an intermediate FIR representation (Faust Imperative Representation), which can be translated to several output languages. An LLVM backend has been previously developed to allows applications to compile a DSP source into executable code in memory, bypassing the external compiler requirement. In some specific situations, embedding the LLVM chain is not possible : for instance Apple does not allow to deploy dynamic compilers on iOS. Thus having an interpreter backend allows to get around this problem and still make Faust code run on those platforms. Interpreter backend The interpreter backend translates the FIR intermediate language into instructions for a virtual machine. A pure C++ interpreter for this instruction set has been implemented. Running and performances The interpreter backend translates the FIR intermediate language into bytecode for a virtual machine. It allows to run programs about 4 to 5 slower than native speed . Moreover this interpreter can be compiled in a special 'trace' mode to automatically detect various execution errors : invalid heap access, mathematical errors or warnings (division by zero, integer overloading....) which helps us to check the compiler semantic and code generation quality. Deployment for developers Given a Faust source code (as a file or a string), calling the createInterpreterDSPFactoryXXX function runs the compilation chain (Faust + interpreter) and generates the \u201cprototype\u201d of the class, as a interpreter-dsp-factory pointer. class interpreter_dsp_factory : public dsp_factory { public: /* Return Factory name */ std::string getName(); /* Return Factory SHA key */ std::string getSHAKey(); /* Return Factory expanded DSP code */ std::string getDSPCode(); /* Creates a new dsp instance */ dsp* createDSPInstance(); }; Note that the library keeps an internal cache of all allocated factories so that the compilation of the same DSP code, that is same source code and same set of 'normalized' (= sorted in a canonical order) compilations options, will return the same (reference counted) factory pointer. You will have to explicitly use deleteInterpreterDSPFactory to properly decrement the reference counter when the factory is no more needed. You can get a unique SHA1 key of the created factory using its getSHAKey method. Next, the createDSPInstance function, corresponding to the new className of C++, instantiates a interpreter-dsp pointer to be used through its interface, connected to the audio chain and controller interfaces. When finished, simply use delete to destroy the dsp instance. class interpreter_dsp : public dsp { public: void metadata(Meta* m); int getNumInputs(); int getNumOutputs(); void init(int samplingRate); void instanceInit(int samplingRate); dsp* clone(); void buildUserInterface(UI* inter); int getSampleRate(); void compute(int count, FAUSTFLOAT** input, FAUSTFLOAT** output); }; Since interpreter_dsp is a subclass of the dsp base class, an object of this type can be used with all already available audio and UI classes, in essence reusing all architecture files already developed for the static C++ class compilation scheme (like OSCUI, httpdUI interfaces etc.), see Developing a new architecture file . Saving/restoring the factory After the DSP factory has been compiled, your application or plugin may want to save/restore it in order to save Faust to interpreter bytecode compilation at next use. To get the internal factory compiled code, several functions are available: writeInterpreterDSPFactoryToMachine allows to get the interpreter bytecode as a string, writeInterpreterDSPFactoryToMachineFile allows to save the interpreter bytecode in a file, To re-create a DSP factory from a previously saved code, several functions are available: readInterpreterDSPFactoryFromMachine allows to create a DSP factory from a string containing the interpreter bytecode, readInterpreterDSPFactoryFromMachineFile allows to create a DSP factory from a file containing the interpreter bytecode. The complete API is available and documented in the installed faust/dsp/interpreter-dsp.h header. 2016-04-07: Web Audio API Faust and the Web Audio API (3) The Faust compiler can now directly be used in a Web page. Thanks to the Emscripten compiler, the Faust compiler itself can be compiled to asm.js JavaScript. This has been done by compiling the libfaust C++ library to the libfaust.js JavaScript library, that exports a unique entry point. Compiling DSP to JavaScript (asm.js) The libfaust.js exported function createAsmCDSPFactoryFromString(...) allows to create a DSP factory from a given DSP program as a source string and a set of compilations parameters, uses the Faust compiler asm.js backend, and produces the complete asm.js module and additional pure JavaScript methods as a string. Then calling JavaScript 'eval' function on this string compiles it in the browser. The dynamically created asm.js module and additional pure JavaScript methods can then be used. This internal code in then wrapped with additional JavaScript code. A DSP \u201cfactory\u201d will be created from the DSP source code with the following 'synchronous' code (if using the 'libfaust.js' library): var factory = faust.createDSPFactory(code, arguments); or possibly (if using the 'libfaustworker.js' library in the 'asynchronous' model): faust.createDSPFactory(code, arguments, callback); where 'code' is the DSP source as a string, and 'arguments' is an array of parameters to be given to the Faust compiler (like '-vec', '-vs 512'...), and 'callback' is a function taking the created 'factory' as argument. When no more used, you'll have to explicitly use the following code the deallocate the factory: faust.deleteDSPFactory(factory); Your application may want to save the already compiled factory as asm.js/JavaScript code to speed-up possible restore at later time: var machine_code = faust.writeDSPFactoryToMachine(factory); And restore the factory with the following code: var factory = faust.readDSPFactoryFromMachine(machine_code); Using DSP instances A fully working DSP \u201cinstance\u201d as a Web Audio node is then created with the code: var dsp = faust.createDSPInstance(factory, audio_context, buffer_size); When no more used, you'll have to explicitly use the following code to deallocate the instance: faust.deleteDSPInstance(dsp); This instance can be used like the statically compiled one, as previously described in this page . Polyphonic instruments Polyphonic instruments can be produced. For a given 'factory' the following code will create a 16 voices polyphonic instance: var dsp = faust.createPolyDSPInstance(factory, audio_context, buffer_size, 16); This instance can be used like the statically compiled one, as previously described in this page . Using Faust JavaScript library The Emscripten compiled Faust library can be used in two ways. Either using the 'libfaust.js' library: <script src=\"libfaust.js\"></script> <script src=\"webaudio-asm-wrapper.js\"></script> or if using worker mode with the following code which loads the 'libfaustworker.js' library: <script src=\"webaudio/webaudio-asm-worker-wrapper.js\"></script> 2016-02-05: Faust Award 2016 Faust Award 2016: deadline June 1, 2016 The Faust Open-Source Software Competition is intended to promote innovative high-quality free audio software developed with the Faust programming language, as well as development tools build around the Faust compiler itself.

Recently standardized WebAssembly language inherits from ideas experimented in both approaches, with the Mozilla vision finnally winning as Robert O'Callahan explains here . Coupled with the WebAudio API , running real-time audio code in the Web now appears to be an achievable goal. WebAssembly is a hot topic in the JavaScript ecosystem. The WebAudio community is eagerly waiting for the AudioWorklet specification, with its promised reduced latency and glitch-free audio rendering, to land in browser development versions, and be tested. Porting well established C/C++ codebase with Emscripten , like the Csound framework as an example, or using DSL languages like Faust, will then naturally beneficiate from improved and more stable performances. The Faust ecosystem already allows to generate static or dynamically compiled WebAssembly based WebAudio nodes . These nodes are still using the deprecated ScriptProcessor WebAudio interface. Premillinary work has been started to be ready as soon at the AudioWorklet model will be testable. In the meantime, work have been started using the WAVM , a standalone VM for WebAssembly, that can load both the standard binary and text wasm format, compiling it in native code using the LLVM chain (generating LLVM IR and compiling it on the fly to native code using LLVM JIT compiler), and running it at (near) native speed. Glue code to load and run Faust generated wasm modules has been written. Validation and benchmarking tools have been developed.

Other languages like Rust (using the mir2wasm tool) experiment direct WebAssembly generation. It seems clear that as WebAssembly specification and implementation stabilize, more and more languages will directly generate wasm to be deployed in browsers. The question of the quality of code generation at each step of the compilation chain will rapidly emerge. While WebAssembly is initially designed to run on the Web, it may be deployed in non Web environnement like nodejs , or even in standalone VM like WAVM . Thus WebAssembly becomes a portable binary format that can be used in a large variety of situations. This is especially of interest for a DSL language like Faust.","title":"Comparing the Faust C++, LLVM IR and wast/wasm backends"},{"location":"community/news/#faust-wastwasm-backend","text":"Faust wast/wasm backend directly produce WebAssembly code from the Faust internal FIR (Faust Imperative Representation) code.

This block will typically be sized to contain all the needed voices for the polyphonic DSP. In both cases, a full description of the DSP state as a JSON string is generated in the module data segment (including memory indexes of all controllers). Loader code will get and decode this JSON description, and use whatever parts of the description it needs to run the DSP code.

Here is the diagram of DSP examples run with reference WAVM runtime, and the three specific optimizations: After generating the LLVM IR code, the WAVM runtime runs a set of LLVM IR to IR optimizations passes.

Since its code can be easily adapted, one can estimate also what can be expected deploying wasm DSP modules in pure native environments , outside of the browser, where some audio specific optimizations may be considered. Measures done on a set of Faust DSP show that WebAssembly code still run slower than C++ or LLVM IR generated code in most cases, up to almost 66% slower in the less favorable examples. This value will typically be a bit worse when deploying in browsers, since float denormal protection code has to be used . Benchmarks in browser wasm runtime still need to be done to confirm or refine these findings. Comparing the Chrome , Firefox and WebKit browsers on OSX El Capitan shows that Chrome is currently the fastest engine in most cases, with Firefox and WebKit quite similar (with a slight plus for WebKit). Comparing the Chrome browser with native engines shows results from 4,8 times slower (filterBank.dsp), 2,8 times slower (sTunedBar6.dsp) up to much more favorable cases (karplus32.dsp). Note that filterBank.dsp example is a bit of a pathological case, since Chrome is significantly slower than Firefox and WebKit in this case, and filterBank.dsp uses a lot of pow(10, x) code that is rewritten an optimized as exp10(x) with the C++ backend path.","title":"Comments and Conclusion"},{"location":"community/news/#2017-08-18-faust-on-the-web","text":"","title":"2017-08-18: Faust on the Web"},{"location":"community/news/#deploying-faust-dsp-on-the-web","text":"EDIT : we are at the Web Audio conference 2017, and it appears that the way we currently extend the ScripProcessorNode with Faust code is not the Right Way...

A robot-probe is placed in a dark place, a cellar. It scans its surroundings with two lasers. The reliefs of the old walls, their imperfections, mold, appear thanks to the perfectly straight lines of the lasers. Its movements are synchronized with a sound program. From these very simple visual and sound choreographies are born an imaginary on its functioning and the origin of its presence. The spectator observes in a mirror a robot which observes and testifies. Does it communicate with other systems? Does it send information? Its energy is precious, like a heartbeat or a breath, it works in a segmented way with periods of silence. Likewise, his movements are slow and relentless.

It is designed to operate as a small embedded server, running either in its own process or within an application. In the spirit of \"smaller is better,\" Arco DSP is mainly delegated to FAUST , leveraging a wide range of existing algorithms. Arco control is delegated to external languages connecting through O2, which supports running Arco within the same application, in a separate process or even on a remote networked host. Arco should be a nice alternative to libpd as an embedded sound engine. The author is mainly using Arco in tandem with Serpent, a real-time Python-like scripting language, but other language bindings are possible. Synthesizer-synthesizer This is a dual-course project for CS378 NLP and CS393P. The goal is to use language model guided program synthesis to synthesize Faust DSP code to ... automatically program synthesizers. Not guaranteed to work. In the slightest. Ambisonics in KMH studios and Lilla salen The general idea behind using ambisonics for diffusing sounds in a space is to, in the first stage, encode an audio signal to a representation of a sound field - a B-format signal. This B-format signal is independent of whatever speaker array the signal will later be diffused on. In the second stage the B-format signal is decoded to the layout of a particular speaker array. In between these two stages a number of transformations may be applied, but the sound source specification may conveniently be specified in the encoder. The decoders are written in Faust. Sardine Sardine is a free/open-source software for Python 3.10+. It turns Python into a musical instrument. You can play it alone or with your friends. With Sardine you can: Play synthesizers and audio samples using SuperCollider. Control synthesizers through MIDI/OSC messages. Interconnect audio/video softwares and/or sound engines. Play collaboratively with your friends. Extend your musical environment using any Python package. Faust written DSP can be used in Sardine. KandiskyScore KandiskyScore is a graphical editor for the analysis and creation of electroacoustic/acousmatic music. It is an html/javascript application. It works perfectly with Firefox, Chrome and Opera and therefore on all Windows, OSX, Linux and other PCs.

The model follows the circuit modelling as seen on the paper Virtual Analog Buchkla 259 wavefolder , using 5 folds. The proposed 2-point BLAMP antialiasing method has been attempted for arbitrary sources as shown here , but it is not sufficient for high frequencies and/or more complex signals. Instead, filtering and light cubic nonlinearity distiorion has been used to round corners and for clipping. The user interface consists of the controls fold for the folding amount, offset for offseting the signal before folding, and lowpass as a final stage one-pole filtering to control the character (too much folding might introduce unwanted higher harmonics for certain signals). The final output is dc-blocked. string-machine This is a virtual-analog string ensemble synthesizer. The implementation is based on a digital model designed by Peter Whiting. The improvement of the model adds various abilities, in particular a virtual-analog emulation of the bucket brigade delay circuit. Most of the DSP code is developed using Faust. Three VST or LV2 are generated: string-machine , string-machine-chorus and string-machine-chorus-stereo . metaFx The metaFx is a control surface for continuous sound transformations in real time, just like the metaSurface64. Like metaSurface64 , it has both its own loop generator and a multi-effects FX engine, but its operation is different, especially for the management of plugin chains and pads. Each mixer on this surface can directly control the gain and the attached plug-ins. It is also possible to control the tracks of an external sequencer (Ardour or Reaper). To do this, the application uses OSC controllable modules that come from the Faust language library that is embedded in the application. Its interest lies in the construction of a parallel sound processing chain in the form of a graph.

Audio DSP processes and effects can be described using Faust. The environment runs as a native application but also in the Web. Faust programs are only supported by the online version . Virtual Rhizome By Vincent Carinola . Virtual Rhizome responds to a proposal by Christophe Lebreton and Jean Geoffroy to compose a work for the original Smart Hand Computer system, developed at the GRAME-CNCM using the Faust language and allowing to play smartphones as an instrument. The work takes the form of a labyrinth, a kind of virtual architecture that could be compared to Borges' \"garden of branching paths\", within which the musician evolves by adapting his gestures to the constraints of different types of situations. Each situation is characterized by an autonomous functioning of the system, that the musician must apprehend in order to find the key allowing him to modify it and to move towards another situation. But in order to orientate himself well, he must create a mental representation of the structure of the work. The performer then becomes an explorer of a world that he unveils, but isn't that what he has always been? Virtual rhizome owes much to the availability and enthusiasm of Jean Geoffroy and Christophe Lebreton. It is amicably dedicated to them. SmartFaust SmartFaust is a concept of musical applications for smartphones. These applications have the particularity of only using the user's gestures and not by tapping on the device's screen. Made for iOS and Android, they can also use the motion sensors of these devices to make them real musical instruments. Smartfaust applications are based on the Faust (Functional Audio Stream) programming language developed by Grame over the last 15 years and recognized as a standard in the field of real-time signal processing for audio. The SmartFaust applications were first used for the creation of the pieces Mephisto (for drums and cell phone ensemble), Belzebuth (participative piece for public equipped with Smartphones), Iblis (for clarinet and cell phone ensemble) and B\u00e9lial (for harp and cell phone ensemble) written by the composer Xavier Garcia. From this same technology were later created the applications \"Geek Bagatelles\" (2016) and \"GameLan\" (2019).

The diagonal colored lines are a guide to where the resonances are: playing over a resonance means that the embouchure and slide length are matched. Playing over white space means that one is between resonances and the note quality won't be as good. The big gray wedge on the upper right indicates that the resonances are very close together there. The vertical dashed lines indicate the rough locations of B-flat (thick lines) and F (thin lines). Other notes are unmarked, and likewise the slide positions. (Just like on a real trombone!) The off-key resonances (7th, 11th, 13th, and 14th) are marked in red. The g and f keys can be used to growl and flutter-tongue, respectively. The audio simulation is written in Faust, which conveniently compiles to WebAssembly and a Web Audio API wrapper. The overall approach used was a digital waveguide model, as described in J. O. Smith III's Digital Waveguide Theory. The lips and bell are adapted from F. Scott's masters thesis. Integrating 1-DoF force feedback interactions in self-contained DMIs By Mathias Kirkegaard . This thesis presents a system for designers of Digital Musical Instruments (DMIs) to explore the integration of 1 degree of freedom (DoF) force feedback interactions in new self-contained instruments. The system developed consists of an open-source graphical tool and a rotary force-feedback device made from commercially available components to facilitate the authoring of audio-haptic applications. Implementing an early prototype is used to inform the development of the graphical editing tool and its integration in an embedded audio-haptic environment using the functional programming language Faust for real-time signal processing.

The Striso board The Striso board is a very expressive music instrument which combines multidimensionally sensitive keys with an innovative note layout that helps understand the structures in music. The keys capture each subtle finger movement, which allows for levels of musical expression previously only known to acoustic instruments. Additionally, accents and sound effects can be added by shaking and moving the instrument as a whole. The internal sound is written in Faust, and is controlled directly by the signals from the keys and motion sensor. External synthesizers can be controlled using MPE MIDI, or using OSC which is easier to set up for Faust synthesizers. The firmware source code is released as open source. Live concatenative granular processing This algorithm addresses signal discontinuity and concatenation artefacts in real-time granular processing with rectangular windowing.

Each situation is characterized by an autonomous functioning of the system, that the musician must apprehend in order to find the key allowing him to modify it and to move towards another situation. But in order to orientate himself well, he must create a mental representation of the structure of the work.

Faust (Functional Audio Stream) is a functional programming language for sound synthesis and audio processing with a strong focus on the design of synthesizers, musical instruments, audio effects, etc. created at the GRAME-CNCM Research Department . Faust targets high-performance signal processing applications and audio plug-ins for a variety of platforms and standards. The core component of Faust is its compiler. It allows to \"translate\" any Faust digital signal processing (DSP) specification to a wide range of non-domain specific languages such as C++, C, LLVM bit code, WebAssembly, Rust, etc. In this regard, Faust can be seen as an alternative to C++ but is much simpler and intuitive to learn. Thanks to a wrapping system called \"architectures,\" codes generated by Faust can be easily compiled into a wide variety of objects ranging from audio plug-ins to standalone applications or smartphone and web apps, etc. The Faust Web IDE Getting Started If You're in a Hurry If you\u2019re in a hurry and just wanna have a look at how Faust programs look like, you can simply check the Faust Examples .

Thanks to a wrapping system called \"architectures,\" codes generated by Faust can be easily compiled into a wide variety of objects ranging from audio plug-ins to standalone applications or smartphone and web apps, etc. The Faust Web IDE","title":"What is Faust?"},{"location":"#getting-started","text":"","title":"Getting Started"},{"location":"#if-youre-in-a-hurry","text":"If you\u2019re in a hurry and just wanna have a look at how Faust programs look like, you can simply check the Faust Examples .","title":"If You're in a Hurry"},{"location":"#if-you-wanna-get-started-with-faust","text":"If you\u2019re looking for a step by step tutorial of approximately 2 hours that will walk you through writing simple Faust programs and give you an overview of what Faust can do, have a look at our Quick Start Tutorial .","title":"If You Wanna Get Started With Faust"},{"location":"#if-youre-looking-for-the-manual","text":"Faust\u2019s syntax and features are thoroughly documented in the Faust Manual .

Smith Real-Time Audio DSP With Faust and FPGAs -- Romain Michon Faust Physical Modeling Workshop Faust has been used for the physical modeling of musical instruments for many years now. Different tools have been developed recently to address the needs of various modeling techniques (e.g., finite difference scheme, waveguides, mass interaction, etc.). The goal of this one day online workshop which took place on Feb. 1, 2021 was to provide a series of interactive one-hour tutorials on these tools as well as some background on their related modeling techniques. Creating Circuit-Bendable Wave-Digital Models of Analog Audio Circuits in Faust -- Dirk Roosenburg Download this workshop's code here Wave-digital models are a well researched and popular approach for creating virtual-analog models of audio circuits for use in audio processing. wdmodels.lib is a new addition to the Faust Libraries that supports easy creation of these models in Faust. In this workshop, we will introduce the technique of wave-digital modeling of circuits by analyzing several audio circuits and exploring their implementation in wdmodels.lib . We also will discuss library support of more complex implementation tasks associated with wave-digital models, such as R-type adaptors and Multiple/Multiport non-linearities. Finally, we will conclude by exploring the capacity of Faust to \"circuit-bend\" our wave-digital models. Note : the workshop's code has been adapted to work with the latest version of the wdmodels.lib library embedded in the Faust Web IDE. You'll see some tiny syntax differences between the video and the new syntax. An Introduction to Mass-Interaction Modelling in Faust -- James Leonard and J\u00e9r\u00f4me Villeneuve Download this workshop's code here This workshop proposes an introduction to mass-interaction (sometimes referred to as mass-spring) modelling for sound synthesis in the Faust environment. After a brief historic introduction to this field, we will give a hands on tutorial on the mi_faust library, which allows simulating modular physical constructions in Faust, as well as online model scripting tools that allow for efficient model design and code generation. We will conclude with ongoing developments and perspectives, in particular regarding performance issues, possible extensions to 3-DoF physics, and the importance of modelling frameworks that allow for a creative approach to physical model design. Finite Difference Schemes Synthesis in Faust -- Riccardo Russo Download this workshop's code here Over the years, Faust proved to be a powerful tool for developing physical modeling synthesis. However, coding finite difference schemes models has always been complicated, in fact, their implementation in imperative programming languages is typically achieved using data structures, which are not available in Faust. This workshop will introduce the fds library, a new tool which allows to code linear, explicit finite difference schemes physical models in Faust, based on a cellular automata formalism. We will start with a brief introduction on how finite difference schemes work and what is their place within the scope physical modeling techniques. Then, we will focus on how to implement the algorithms we obtained on paper in Faust and, lastly, we will see how the fds library can be used to code such algorithms in a much easier way. By the end of the tutorial you should have quite an understanding on the basic principles of finite difference schemes, on the roles of the different functions inside the fds library and on how they can be used to easily obtain a working fds physical model. break Introduction to the Faust Physical Modeling Toolkit -- Romain Michon Download this workshop's code here A series of tools to facilitate the implementation of waveguide and modal physical models of musical instruments have been developed over the years by the Faust team to become the \"Faust Physical Modeling Toolkit.\" This comprises the Faust Physical Modeling library ( pm.lib ) as well as mesh2faust , a tool to convert 3D meshes into modal physical models compatible with pm.lib . During this workshop, we will provide a step-by-step tutorial on how to use these different tools to implement various kinds of physical models from scratch.

Physical models normally start out as differential equations which are then digitized to yield finite-difference schemes as were discussed earlier in this workshop. Wave digital and digital waveguide formulations were also discussed. Two additional topics are state-space models and modal representations which can be obtained by diagonalizing state-space models. As a result, this talk focuses primarily on state-space models and how to diagonalize them.","title":"Events"},{"location":"community/events/#events","text":"","title":"Events"},{"location":"community/events/#faust-day-2023","text":"Faust Day took place at the Center for Computer Research in Music and Acoustics (CCRMA) at Stanford University on May 20th, 2023.

The compute method is repeatedly called in a loop (taking 100% of a core) which duration is measured. Results as MBytes/sec as well a DSP CPU load in % of a 1024 frames, 44.1 kHz audio buffer are displayed. On the following pages, just hit the Start benchmark button, and wait for the result to be displayed. Note that since the computation is done in the main JavaScript thread, don't disturb your machine too much to get a reliable result. The pages can typically be used to compare the performances of different browsers: bench/clarinetMIDI.html bench/djembe.html bench/filterBank.html bench/freeverb.html bench/frenchBell.html bench/guitarEffectChain.html bench/karplus.html bench/karplus32.html bench/kisana.html bench/spectralLevel.html bench/stunedBar6.html bench/violinMIDI.html bench/zitaRev.html Testing the denormal issue A specific problem occurs when audio computation produces denormal float values, which is quite common with recursive filters, and can be extremely costly to compute on some processors like the Intel family for instance. Even with the software FTZ mode, we still see huge DSP CPU issue in some cases like this djembe physical model based on simple biquad filters: modules/djembe.html On OSX for instance, open the Activity Monitor tool and look as your browser CPU use. Then hit the checkbox to start playing, and hit it again to stop it. Silence should be produced, but actually very small sample values (= subnormals) are generated. If your machine uses an Intel CPU, you will see CPU raise quite rapidly ! (tested on a MacBook Pro OSX El Capitan 2,2 GHz Intel Core i7). Benchmark tools For developers, benchmark tools allow to generate HTML pages to test your DSP. Look in particular at the faust2benchwasm script. Dynamic compilation chain testing page A more complete testing page for monophonic and polyphonic MIDI aware DSP, ScriptProcessor or AudioWorklet mode, FTZ selection mode is available here . 2017-11-07: 1st IFC 1st International Faust Conference - Johannes Gutenberg University, Mainz (Germany), July 17-18, 2018 The International Faust Conference IFC-18 will take place at the Johannes Gutenberg University of Mainz (Germany) on July 17-18, 2018.

Contact Please, address your questions to: ifc18@muwiinfa.geschichte.uni-mainz.de Conference website: http://www.ifc18.uni-mainz.de 2017-10-20: New Editor New Faust Editor We are very happy to announce the online Faust Editor . It can be used to edit , compile and run Faust code from any recent Web Browser with WebAssembly support. This editor works completely on the client side and it is therefore very convenient for situations with many simultaneous users (workshops, classrooms, etc.). It embeds the latest version of the Faust compiler with an efficient WebAssembly backend and offers polyphonic MIDI support. Features The editor engine is based on codemirror . It offers syntax highlighting , auto completion and direct access to the online documentation . The documentation command (ctrl-d) uses the function name at the cursor position to locate to the relevant information. Recommended Browsers The recommended browsers are the latest versions of Firefox and Chrome. Chrome is recommended for MIDI, but it requires an https connexion to use the audio inputs. On the other hand MIDI is not supported by Firefox. Useful links Editor : the official link, https://grame-cncm.github.io/fausteditorweb/ : an alternative link on GitHub. Because this is an https address, audio inputs will work (but not the export function), https://github.com/grame-cncm/fausteditorweb : the GitHub repository. 2017-09-15: Performances... Performances of audio DSP code compiled in WebAssembly Porting and running large C/C++ code base on the Web have been the subject of several competing projects in the recent years, from Google NaCl/PNaCl to Mozilla asm.js . Recently standardized WebAssembly language inherits from ideas experimented in both approaches, with the Mozilla vision finnally winning as Robert O'Callahan explains here . Coupled with the WebAudio API , running real-time audio code in the Web now appears to be an achievable goal. WebAssembly is a hot topic in the JavaScript ecosystem. The WebAudio community is eagerly waiting for the AudioWorklet specification, with its promised reduced latency and glitch-free audio rendering, to land in browser development versions, and be tested. Porting well established C/C++ codebase with Emscripten , like the Csound framework as an example, or using DSL languages like Faust, will then naturally beneficiate from improved and more stable performances. The Faust ecosystem already allows to generate static or dynamically compiled WebAssembly based WebAudio nodes . These nodes are still using the deprecated ScriptProcessor WebAudio interface. Premillinary work has been started to be ready as soon at the AudioWorklet model will be testable. In the meantime, work have been started using the WAVM , a standalone VM for WebAssembly, that can load both the standard binary and text wasm format, compiling it in native code using the LLVM chain (generating LLVM IR and compiling it on the fly to native code using LLVM JIT compiler), and running it at (near) native speed. Glue code to load and run Faust generated wasm modules has been written. Validation and benchmarking tools have been developed. Performances comparison with the C++ and LLVM IR Faust backends is the subject of this post. Comparing the Faust C++, LLVM IR and wast/wasm backends The WebAssembly approach promises near native performances for C/C++ written code compiled to WebAssembly using the Emscripten tool chain. Other languages like Rust (using the mir2wasm tool) experiment direct WebAssembly generation. It seems clear that as WebAssembly specification and implementation stabilize, more and more languages will directly generate wasm to be deployed in browsers. The question of the quality of code generation at each step of the compilation chain will rapidly emerge. While WebAssembly is initially designed to run on the Web, it may be deployed in non Web environnement like nodejs , or even in standalone VM like WAVM . Thus WebAssembly becomes a portable binary format that can be used in a large variety of situations. This is especially of interest for a DSL language like Faust. Faust wast/wasm backend Faust wast/wasm backend directly produce WebAssembly code from the Faust internal FIR (Faust Imperative Representation) code. Generated modules are rather light since they define a very simple ABI to be used by the loader code. Two generation models have been defined: in monophonic mode the wast/mast module internally allocates a memory block to be used for the DSP state (controllers, delays lines, waveforms...) as well as audio buffers. in polyphonic mode, the memory block will be allocated by the loader environnement. This block will typically be sized to contain all the needed voices for the polyphonic DSP. In both cases, a full description of the DSP state as a JSON string is generated in the module data segment (including memory indexes of all controllers). Loader code will get and decode this JSON description, and use whatever parts of the description it needs to run the DSP code. In particular, control memory zones (corresponding to the UI items like buttons, sliders, bargraph...) can be directly read/written by the wrapper code. Benchmark of C++, LLVM IR and wast/wasm generated code Since Faust already generates C++ or LLVM IR code, the performances of those two backends can be compared with the new wasm one. Using the WAVM C++ written machine allows to deploy the same measuring code . The first benchmark compares the speed of C++, LLVM IR and wasm backends running a set of DSP, running on a MacBook Pro 2,2 GHz Core I7 with OSX El capitan. The same 4.0 version of LLVM toolchain has been used with the three backend. C++ and LLVM IR code has been compiled with the -Ofast optimization flag, the WAVM runtime is the standard version one (without any specific audio optimization, see later): The diagrams clearly shows that the wasm code is still slower than C++ or LLVM IR code, but speed difference is not so high in most cases. Some DSP behaviours need to be understood in more details. Optimizing the WAVM runtime for audio code The WAVM runtime strictly conforms to the WebAssembly specification, thus behaving as a interesting base reference. In the audio domain, the deployed code is usually compiled with specific optimization flags. Since C++ WAVM runtime can be hacked quite easily, we did several changes into the reference implementation to gain some speed: removing the atomic flag in all load/store that are added to pass all spec WebAssembly tests. adding the equivalent of -fast-math compilation flag that have to be done at LLVM IR and JIT (= native) generation steps. and finally simplifying some mathematical operators, using their standard definition instead of the specific WAVM coded ones that strictly implement WebAssembly official semantic (see for instance the definition of f32.min/f32.max operations). Here is the diagram of DSP examples run with reference WAVM runtime, and the three specific optimizations: After generating the LLVM IR code, the WAVM runtime runs a set of LLVM IR to IR optimizations passes. It remains to be tested if adding more optimization passes (especially the auto-vectorizations ones) could help producing even better code. WebAssembly module optimization with Binaryen Binaryen is a compiler and toolchain infrastructure library for WebAssembly , written in C++. We tested the wasm-opt tool at -O3 level on Faust generated wasm modules to estimate which speedup we can expect. The following diagram shows limited gains, with no more than 5% in some of the tested cases: Float denormal handling A specific problem occurs when audio computation produces denormal float values, which is quite common with recursive filters, and can be extremely costly to compute on some processors like the Intel family for instance. A Flush To Zero (FTZ) mode for denormals can usually be set at hardware level, but it not yet available in the WebAssembly MVP version, which strictly conform to the IEEE 754 norm 8. Thus an automatic software strategy which consists in adding FTZ code in all recursive loops has been implemented in the Faust compiler. To activate it, the -ftz compilation parameter must be used at compilation time. The -ftz 1 mode adds a test in each recursive loop which uses the fabs function and a threshold to detect subnormal samples (slower). The -ftz 2 mode adds a test in each recursive loop which uses a mask to detect subnormal samples (faster). Even if using software ftz is not strictly needed in our benchmark chain (since the C++ WAVM uses the ftz hardware protection mode), we can still compare the speed of the different ftz options. Here is the result of code generated with -ftz from 0 to 2: Comparing three browsers on OSX El Capitan HTML test pages were prepared to compare the performances of the three main browsers on OSX El Capitan. The DSP code is compiled with float denormal protection on (-ftz 2). The generated wasm module compute method is called repeatedly in a timed loop, using successive slices of a big allocated circular audio buffer to avoid cache effects. Here are the results: The fasted one (Chrome for now) can be compared with C++, LLVM IR, WAVM native engines, all compiled with float denormal protection on (-ftz 2): Comments and Conclusion Testing wasm JIT machines inside browsers is not an easy task. The C++ WAVM runtime revealed to be an excellent tool to compare the Faust C++, LLVM IR and wasm backend. Since its code can be easily adapted, one can estimate also what can be expected deploying wasm DSP modules in pure native environments , outside of the browser, where some audio specific optimizations may be considered. Measures done on a set of Faust DSP show that WebAssembly code still run slower than C++ or LLVM IR generated code in most cases, up to almost 66% slower in the less favorable examples. This value will typically be a bit worse when deploying in browsers, since float denormal protection code has to be used . Benchmarks in browser wasm runtime still need to be done to confirm or refine these findings. Comparing the Chrome , Firefox and WebKit browsers on OSX El Capitan shows that Chrome is currently the fastest engine in most cases, with Firefox and WebKit quite similar (with a slight plus for WebKit). Comparing the Chrome browser with native engines shows results from 4,8 times slower (filterBank.dsp), 2,8 times slower (sTunedBar6.dsp) up to much more favorable cases (karplus32.dsp). Note that filterBank.dsp example is a bit of a pathological case, since Chrome is significantly slower than Firefox and WebKit in this case, and filterBank.dsp uses a lot of pow(10, x) code that is rewritten an optimized as exp10(x) with the C++ backend path. 2017-08-18: Faust on the Web Deploying Faust DSP on the Web EDIT : we are at the Web Audio conference 2017, and it appears that the way we currently extend the ScripProcessorNode with Faust code is not the Right Way... Part of the post concerning the exposed API will probably change a bit in the near future... Using latest developments done for the Web (the new WebAssembly backends and libfaust library compiled in WebAssembly with Emscripten), statically and dynamically Faust generated WebAudio nodes can be easily produced and deployed on the Web. Deploying statically compiled Faust WebAudio nodes From a foo.dsp source file, JavaScript and the associated WebAssembly files can be produced with the following script: faust2wasm foo.dsp This will generate a foo.wasm file with the WebAssembly module as binary code, as well as a foo.js wrapper file containing the code needed to turn the Faust DSP in a fully working WebAudio node (using an extended ScriptProcessor node). The name of the Faust DSP code file is used to define the final ScriptProcessorNode constructor name. So for instance if osc.dsp file is compiled, the following faust.createosc function will be generated: /** * Create a 'monophonic' ScriptProcessorNode Web Audio object * by loading and compiling the Faust wasm file * * @param context - the Web Audio context * @param buffer_size - the buffer_size in frames * @param callback - a callback taking the created ScriptProcessorNode as parameter, * or null in case of error */ faust.createosc = function(context, buffer_size, callback) The resulting object is an extended ScriptProcessorNode, to be used as a regular node (like connected to other WebAudio nodes), but which also adds the Faust specific API as defined in the equivalent C++ generated dsp class (see the architecture/faust/dsp/dsp.h header for more technical details), as well as JavaScript more specific functions. For instance the following ones will have to be used to control the node: var paths = node.getParams(); // get the set of paths to read/write input control parameters Then knowing the path for a given parameter, the following function is used to change the parameter value: node.setParamValue(\"/Oscillator/freq\", 0.6); A full JSON description of the node with the complete UI, can be retrieved with: var json = node.getJSON(); The complete usable API is fully documented in the generated JavaScript file in the Public API to be used to control the WebAudio node section. A simple example Web page A simple Web page using the files generated by faust2wasm on the noise.dsp file can be defined with the following parts: <!-- Load 'faust2wasm' script generated .js file --> <script src=\"noise.js\"></script> A slider to control the noise volume parameter is defined with: <P> Noise volume: <input type=\"range\" oninput=\"changeVolume(event) \"min=\"0\" max=\"1\" value=\"0.5\" step=\"0.01\"/> The WebAudio context is created and the noise slide hander is defined with: var isWebKitAudio = (typeof (webkitAudioContext) !== \"undefined\"); var audio_context = (isWebKitAudio) ? new webkitAudioContext() : new AudioContext(); var noise = null; // Slider handler to change the 'noise' volume function changeVolume(event) { noise.setParamValue(\"/Noise/Volume\", parseFloat(event.target.value)); } A startnoise function which creates the Faust WebAudio node is defined with: function startnoise() { // Create the Faust generated node faust.createnoise(audio_context, 1024, function (node) { noise = node; console.log(noise.getJSON()); // Print paths to be used with 'setParamValue' console.log(noise.getParams()); // Connect it to output as a regular WebAudio node noise.connect(audio_context.destination); }); } An finally the load handler is defined to activate the code: window.addEventListener(\"load\", startnoise); Look at the Noise and OSC online pages for the complete code. Note that pages loading an additional .wasm file cannot directly be loaded in Chrome. You'll have to start a local server (using the python -m SimpleHTTPServer command for instance) and access them with their http:// based URL. Generating Polyphonic WebAudio nodes Assuming that the compiled Faust DSP file is polyphonic ready , a polyphonic ready WebAudio node can be created with the -poly parameter, and will generate the following constructor for the node (where the mydsp part will be replaced by the actual DSP name): /** * Create a 'polyphonic' ScriptProcessorNode Web Audio object * by loading and compiling the Faust wasm file * to be use for the voice, and allocating the number of needed voices * * @param context - the Web Audio context * @param buffer_size - the buffer_size in frames * @param polyphony - the number of polyphonic voices * @param callback - a callback taking the created ScriptProcessorNode * as parameter, or null in case of error */ faust.createmydsp_poly = function(context, buffer_size, polyphony, callback) Polyphonic nodes have an extended API to be controled with MIDI messages: /** * Instantiates a new polyphonic voice. * * @param channel - the MIDI channel (0..15, not used for now) * @param pitch - the MIDI pitch (0..127) * @param velocity - the MIDI velocity (0..127) */ keyOn = function (channel, pitch, velocity) /** * De-instantiates a polyphonic voice. * * @param channel - the MIDI channel (0..15, not used for now) * @param pitch - the MIDI pitch (0..127) * @param velocity - the MIDI velocity (0..127) */ keyOff = function (channel, pitch, velocity) /** * Gently terminates all the active voices. */ allNotesOff = function () Look at the JavaScript public documentation section for the complete description. Extended control with -comb parameter The faust2wasm tool can be used with the -comb parameter to compile several DSP files and contatenate all JavaScript code in a unique resulting comb.js file (possibly to be used in -poly mode also). Generating fully working self-contained HTML pages The faust2webaudiowasm script can be used to generate a fully working self-contained HTML page, with a SVG/CSS a Graphical User Interface. From the osc.dsp Faust DSP source file, it will generate an osc.html file: faust2webaudiowasm osc.dsp Assuming that the compiled Faust DSP file is polyphonic ready, the -poly parameter can be used to generate a polyphonic MIDI controlable instrument, to be used with a MIDI application or device. The -links generates the DSP processor SVG representation, and links to the original DSP file as well as generated SVG files, so that the HTML page can possibly be deployed as a reusable Faust DSP resource. WebAssembly module optimization Assuming that you have Binaryen tools installed on your machine, the faust2wasm and faust2webaudiowasm scripts can take an additional -opt parameter to allow WebAssembly module optimization. Deploying dynamically compiled Faust WebAudio nodes Since the libfaust library is available for the Web, it becomes possible to embed the complete dynamic compilation chain in a Web page , from the Faust DSP source to the executable WebAudio node. First the following resources (located on the Faust GitHub in architecture/webaudio folder) have to be loaded in the page: <!-- Load 'libfaust' library and wrapper code --> <script src=\"libfaust-wasm.js\"></script> <script src=\"webaudio-wasm-wrapper.js\"></script> Then the two following functions are used to generate factories, creating later on monophonic or polyphonic instances (this is necessary because of the way internal WebAssembly memory is managed): /** * Create a DSP factory from source code as a string to be used to create monophonic DSP * * @param code - the source code as a string * @param argv - an array of parameters to be given to the Faust compiler * @param callback - a callback taking the created DSP factory as parameter, * or null in case of error */ faust.createDSPFactory = function (code, argv, callback) /** * Create a DSP factory from source code as a string to be used to create polyphonic DSP * * @param code - the source code as a string * @param argv - an array of parameters to be given to the Faust compiler * @param callback - a callback taking the created DSP factory as parameter, * or null in case of error */ faust.createPolyDSPFactory = function (code, argv, callback) The two following functions are used to generate monophonic or polyphonic Faust WebAudio nodes: /** * Create a ScriptProcessorNode Web Audio object from a factory * * @param factory - the DSP factory * @param context - the Web Audio context * @param buffer_size - the buffer_size in frames * @param callback - a callback taking the created ScriptProcessorNode as parameter, * or null in case of error */ faust.createDSPInstance = function (factory, context, buffer_size, callback) /** * Create a 'polyphonic' 'ScriptProcessorNode Web Audio object from a factory * * @param factory - the DSP factory * @param context - the Web Audio context * @param buffer_size - the buffer_size in frames * @param polyphony - the number of polyphonic voices * @param callback - a callback taking the created ScriptProcessorNode as parameter, * or null in case of error */ faust.createPolyDSPInstance = function (factory, context, buffer_size, polyphony, callback) The resulting nodes have the same API as statically compiled nodes described in the first section, so can be controlled the same way, including the polyphonic ones. Here is a code example using faust.createDSPFactory and faust.createDSPInstance : var isWebKitAudio = (typeof (webkitAudioContext) !== \"undefined\"); var audio_context = (isWebKitAudio) ? new webkitAudioContext() : new AudioContext(); var dsp_code = \"import(\\\"stdfaust.lib\\\"); vol = hslider(\\\"volume [unit:dB]\\\", 0, -96, 0, 0.1) : ba.db2linear : si.smoo; freq = hslider(\\\"freq [unit:Hz]\\\", 1000, 20, 24000, 1); process = vgroup(\\\"Oscillator\\\", os.osc(freq) * vol);\"; var osc = null; var libraries_url = \"/modules/libraries/\"; function startosc() { // Prepare argv list var argv = []; argv.push(\"-ftz\"); argv.push(\"2\"); argv.push(\"-I\"); argv.push(libraries_url); // Dynamically create the Faust generated node from explicit DSP source in 'dsp_code' faust.createDSPFactory(dsp_code, argv, function (factory) { faust.createDSPInstance(factory, audio_context, 1024 function (node) { osc = node; console.log(osc.getJSON()); // Print paths to be used with 'setParamValue' console.log(osc.getParams()); // Connect it to output as a regular WebAudio node osc.connect(audio_context.destination); })}); } The Dynamic OSC page demonstrates the dynamic OSC complete code (based on the example seen before). The Dynamic Organ page demonstrates a polyphonic organ instrument, which loads a DSP from an url, and ready to be controlled with a MIDI device or application. Look at the Dynamic Faust compiler page for a more complete use-case of the dynamic compiler. Float denormal handling A specific problem occurs when audio computation produces denormal float values, which is quite common with recursive filters, and can be extremely costly to compute on some processors like the Intel family for instance. A Flush To Zero (FTZ) mode for denormals can usually be set at hardware level, but it not yet available in the WebAssembly MVP version, which strictly conform to the IEEE 754 norm 8. Thus an automatic software strategy which consists in adding FTZ code in all recursive loops has been implemented in the Faust compiler. To activate it, the -ftz compilation parameter must be used at compilation time. The -ftz 1 mode adds a test in each recursive loop which uses the fabs function and a threshold to detect subnormal samples (slower). The -ftz 2 mode adds a test in each recursive loop which uses a mask to detect subnormal samples (faster). Use for example the following line to active software denormal handing when using faust2wasm tool: faust2wasm -ftz 2 foo.dsp The same for the faust2webaudiowasm tool: faust2webaudiowasm -ftz 2 foo.dsp For dynamic compilation, the -ftz v flag will have to be added in the argv parameter in faust.createDSPFactory or faust.createPolyDSPFactory , like for instance: faust.createPolyFactory(dsp_code, ['-ftz', '2'], callback); 2017-06-16: Memory allocator Using a custom memory allocator From a DSP source file, the Faust compiler typically generates a C++ class. When a rdtable item is used on the source code, the C++ class will contain a table shared by all instances of the class. By default, this table is generated as a static class array, and so allocated in the application global static memory. In some specific case (usually in more constrained deployment cases), managing where this data is allocated is crucial. By extension this post explains how a custom memory allocator can be used to precisely control the DSP memory allocation. Faust -mem option to control memory related code generation A new -mem compiler parameter has been added in the Faust compiler, starting from the 0.9.103 version (or 2.1.4 in Faust2 branch). This parameter will change the way static shared tables are generated. The table is allocated as a class static pointer allocated using a custom memory allocator , which has the following propotype: struct dsp_memory_manager { virtual ~dsp_memory_manager() {} virtual void* allocate(size_t size) = 0; virtual void destroy(void* ptr) = 0; }; Taking the following Faust DSP example: process = (waveform {10,20,30,40,50,60,70}, %(7)~+(3) : rdtable), (waveform {1.1,2.2,3.3,4.4,5.5,6.6,7.7}, %(7)~+(3) : rdtable); Here is the generated code in default mode: ... int mydsp::itbl0[7]; float mydsp::ftbl0[7]; static void classInit(int samplingFreq) { SIG0 sig0; sig0.init(samplingFreq); sig0.fill(7,itbl0); SIG1 sig1; sig1.init(samplingFreq); sig1.fill(7,ftbl0); } virtual void init(int samplingFreq) { classInit(samplingFreq); instanceInit(samplingFreq); } virtual void instanceInit(int samplingFreq) { instanceConstants(samplingFreq); instanceResetUserInterface(); instanceClear(); } ... The two itbl0 and ftbl0 tables are static class arrays. They are filled in the classInit method. The architecture code will typically call the init method (which calls classInit ) on a given DSP, to allocate class related arrays and the DSP itself. If several DSP are going to be allocated, calling classInit only once then the instanceInit method on each allocated DSP is the way to go. In the new -mem mode, the generated C++ code is now: ... int* mydsp::itbl0 = 0; float* mydsp::ftbl0 = 0; dsp_memory_manager* mydsp::fManager = 0; static void classInit(int samplingFreq) { SIG0 sig0; itbl0 = static_cast<int*>(fManager->allocate(sizeof(int) * 7)); sig0.init(samplingFreq); sig0.fill(7,itbl0); SIG1 sig1; ftbl0 = static_cast<float*>(fManager->allocate(sizeof(float) * 7)); sig1.init(samplingFreq); sig1.fill(7,ftbl0); } static void classDestroy() { fManager->destroy(itbl0); fManager->destroy(ftbl0); } virtual void init(int samplingFreq) {} virtual void instanceInit(int samplingFreq) { instanceConstants(samplingFreq); instanceResetUserInterface(); instanceClear(); } ... The two itbl0 and ftbl0 tables are generated a class static pointers. The classInit method takes the additional dsp_memory_manager object used to allocate tables. A new classDestroy method is available to deallocate the tables. Finally the init method is now empty, since the architecure file is supposed to use the classInit/classDestroy method once to allocate and deallocate static tables, and the instanceInit method on each allocated DSP. Control of the DSP memory allocation An architecture file can now define its custom memory manager by subclassing the dsp_memory_manager abstract base class, and implement the two required allocate and destroy methods. Here is an example of a simple heap allocating manager: struct malloc_memory_manager : public dsp_memory_manager { virtual void* allocate(size_t size) { void* res = malloc(size); cout << \"malloc_manager: \" << size << endl; return res; } virtual void destroy(void* ptr) { cout << \"free_manager\" << endl; free(ptr); } }; Controlling the table memory allocation To control table memory allocation, the architecture file will have to do: // Allocate a custom memory allocator malloc_memory_manager manager; // Setup manager for the class mydsp::fManager = &manager; // Allocate the dsp instance using regular C++ new mydsp* dsp = new mydsp(); // Allocate static tables (using the custom memory allocator) mydsp::classInit(48000); // Initialise the given instance dsp->instanceInit(48000); ... ... // Deallocate the dsp instance using regular C++ delete delete dsp; // Deallocate static tables (using the custom memory allocator) mydsp::classDestroy(); Controlling the complete DSP memory allocation Full control the DSP memory allocation can be done using C++ placement new : #include <new> // Allocate a custom memory allocator malloc_memory_manager manager; // Setup manager for the class mydsp::fManager = &manager; // Placement new using the custom allocator mydsp* dsp = new(manager.allocate(sizeof(mydsp))) mydsp(); // Allocate static tables (using the custom memory allocator) mydsp::classInit(48000); // Initialise the given instance dsp->instanceInit(48000); ... ... // Calling the destructor dsp->~mydsp(); // Deallocate the pointer itself using the custom memory allocator manager.destroy(dsp); // Deallocate static tables (using the custom memory allocator) mydsp::classDestroy(); More complex custom memory allocators can be developed by refining this malloc_memory_manager example, possibly defining real-time memory allocators...etc... The OWL architecture file already uses this new custom memory allocator model. This is a work in progress: in the Faust2 branch, this model is still not supported yet beside the C++ backend custom memory allocator is not yet supported is additional DSP classes (like the mydsp_poly defined in the achitecture/faust/dsp/poly-dsp.h header). 2017-04-26: Optimizing... Optimizing the DSP CPU usage The Faust compiler has as lot of different compilation parameters to play with. Discovering them for a given DSP program is something that can be automated. Two measure_dsp and dsp_optimizer classes are available for developers to measure DSP CPU use directly in their code. Two more friendly faustbench and faustbench-llvm tools have been developed using them. They allow to discover the best Faust compiler parameters, to be used later on with faust2xx scripts, faustgen~ Max/MSP external or FaustLive . The measure_dsp and dsp_optimizer DSP decorator classes The measure_dsp class defined in the faust/dsp/dsp-bench.h file allows to decorate a given DSP object and measure its compute method CPU consumption. Results are given in Megabytes/seconds (higher is better). Here is a C++ code example of its use: static void bench(dsp* dsp, const string& name) { // Init the DSP dsp->init(48000); // Wraps it with a 'measure_dsp' decorator measure_dsp mes(dsp, 1024, 5); // Measure the CPU use mes.measure(); // Print the stats cout << name << \" CPU use : \" << mes.getStats() << endl; } Only part of the Faust2 branch and defined in the faust/dsp/dsp-optimizer.h file, the dsp_optimizer class uses the libfaust library and its LLVM backend to dynamically compile DSP objects produced with different Faust compiler options, and then measure their DSP CPU. Here is a C++ code example of its use: static void dynamic_bench(const string& dsp_source) { // Init the DSP optimizer with the dsp_source to compile // (either the filename or source code string) dsp_optimizer optimizer(dsp_source, \"/usr/local/share/faust\", \"\", 1024); double value; // Discover the best set of parameters vector<string> options = optimizer.findOptimizedParameters(value); // Print the result cout << \"Best value is for '\" << argv[1] << \"' is : \" << value << \" with \"; for (int i = 0; i < options.size(); i++) { cout << options[i] << \" \"; } cout << endl; } Using the faustbench tool The faustbench tool uses the C++ backend to generate a set of C++ files produced with different Faust compiler options. All files are then compiled in a unique binary that will measure DSP CPU of all versions of the compiled DSP. The tool is supposed to be launched in a terminal, but it can be used to generate an iOS project, ready to be launched and tested in Xcode. Here are the available options: faustbench [-ios] [Additional Faust options (-vec -vs 8...)] <file.dsp> Use '-ios' to generate an iOS project Use 'export CXX=/path/to/compiler' before running faustbench to change the C++ compiler Use 'export CXXFLAGS=options' before running faustbench to change the C++ compiler options Here is a trace of its use: faustbench karplus32.dsp Selected compiler is g++ with CXXFLAGS = -Ofast -scal : 77.5123 -vec -lv 0 -vs 4 : 64.2194 -vec -lv 0 -vs 8 : 80.8951 -vec -lv 0 -vs 16 : 106.244 ..... -vec -lv 1 -vs 128 -g : 130.635 -vec -lv 1 -vs 256 -g : 134.335 -vec -lv 1 -vs 512 -g : 135.352 Best value is : 136.235 with -vec -lv 0 -vs 512 Using the faustbench-llvm tool Available in the faust2 branch only, the faustbench-llvm tool uses the libfaust library and its LLVM backend to dynamically compile DSP objects produced with different Faust compiler options, and then measure their DSP CPU. In the main Faust folder, use make bench && sudo make install to build and install the tool.

JUCE is used in particular for its GUI and plugins libraries. A set of architecture files have been developed to deploy standalone or plugins built from Faust code. They allow to automatically generate the GUI from the Faust program, possibly supporting polyphonic instruments, and be controlled by MIDI or OSC messages. The architecture files are then combined to produce ready to compile JUCE applications or plugins, using tools that are part of the Faust distribution. They can also be accessed using the Faust online compiler. faust2juce script faust2juce transforms a Faust DSP program into a fully working JUCE standalone application or plugin, which can possibly be controlled with MIDI or OSC messages. Read its complete description here . You'll have to get a recent github version of Faust tree to use it. Using the online compiler The Faust online compiler has been updated to provide new 'juce' targets. Note that only some of the possible compilation options are availble for now: the application target produces a standalone MIDI controlable application (using Faust polyphonic code if the Faust source code is polyphonic aware) the plug-in target produces a MIDI controlable mono or polyphonic plugin (using Faust polyphonic code if the Faust source code is polyphonic aware) the jsynth target produces a MIDI controlable mono or polyphonic plugin (using JUCE polyphonic Synthesizer if the Faust source code is polyphonic aware) Directly using faust2juce provides the full control of the generated target with access to all possible compilation parameters. Graph of Faust generated plugins Here is an example of three Faust generated plugins running in JUCE plugin host: Using libfaust and LLVM An alternative to faust2juce static-compilation model, is to use Oliver Larkin's juce_faustllvm module, also used in his pMix2 tool . 2017-01-13: WebAssembly... Faust WebAssembly backend WebAssembly was born with the premise of creating a safe, portable and fast to load and execute format suitable for the web. WebAssembly its not a programing language but a compilation target with a text and binary specs. That means that other low level languages like C/C++, Rust, Swift, etc. can compile to WebAssembly. Specified and developed by principal browser compagnies (Google, Mozilla, Microsoft and Apple), this new format aims to finally replace the more hackish \"asm.js\" format initialy developed by Mozilla. Development versions of Chrome and Firefox can already execute it. To get an early preview of this experimental technology, at your own risk: on Chrome Canary , open chrome://flags/#enable-webassembly and enable the switch on Firefox Nightly , open about:config and set javascript.options.wasm to true See a preview of Microsoft Edge support and follow Safari support on WebKit\u2019s feature status . WebAssembly backends New WebAssembly backends have been added in the faust2 development branch. They allow to generate textual or binary WebAssembly code. 'wast' textual backend The 'wast' backend allows to generate textual WebAssembly code (in s-expression like format). Note that as of january 2017, the official textual format is not yet fully specified, thus we follow the format used in the binaryen tool . Use the following command to generate the textual output in the terminal for a given foo.dsp file. faust -lang wast foo.dsp The following command: faust -lang wast foo.dsp -o foo.wast will generate the foo.wast textual WebAssembly output file as well as an additional foo.js JavaScript file containing glue code. 'wasm' binary backend The 'wasm' backend allows to generate binary WebAssembly code. Use the following command to generate the binary output in the terminal for a given foo.dsp file. faust -lang wasm foo.dsp The following command: faust -lang wasm foo.dsp -o foo.wasm will generate the foo.wast binary WebAssembly output file as well as an additional foo.js JavaScript file containing glue code. Generating static HTML pages WebAssembly code can be feeded into WebAudio JavaScript nodes, which can then be used like any other native WebAudio node. Two scripts are available to generate static WebAudio html pages from a given foo.dsp source file with the generated html/css/svg user interface: faust2webaudiowast foo.dsp will generate the textual WebAssembly output, use binaryen wasm-as tool to convert the wast to wasm format (you'll have to compile and install the binaryen tools on your machine), and produce a self-contained html page. faust2webaudiowasm foo.dsp will generate the binary WebAssembly output that can directly be loaded by the produced self-contained html page. Page containing polyphonic instruments can be generated with the following commands: faust2webaudiowast -poly foo.dsp to use the 'wast' backend and a polyphonic ready foo.dsp, and create a self-contained html page ready to be used with a MIDI instrument. faust2webaudiowasm -poly foo.dsp to use the 'wasm' backend and a polyphonic ready foo.dsp, and create a self-contained html page ready to be used with a MIDI instrument. 2016-10-17: Faust Award 2016 The Faust Open Source Software Competition aims at promoting innovative high-quality free audio software developed with Faust, a functional programming language for realtime signal processing and sound synthesis. The competition is sponsored by GRAME , Centre National de Cr\u00e9ation Musicale Faust Award 2016 to Ambitools The Faust Award 2016 was attributed by an international committee composed of : Jean-Louis Giavitto (IRCAM, Paris, France), Albert Graef (Johannes Gutenberg U., Mainz, Germany), Pierre Jouvelot (Ecole des Mines, Paris, France), Victor Lazzarini (Maynooth U., Maynooth, Ireland), Romain Michon (Stanford U., Palo Alto, USA) Yann Orlarey (GRAME, Lyon, France), Dave Phillips (musician, journalist, and educator, USA) Laurent Pottier (U. Jean Monnet, Saint-Etienne, France), Julius Smith (Stanford U., Palo Alto, USA) to Ambitools , a set of tools for real-time 3D sound field synthesis using higher order ambisonics (HOA). Ambitools is developed by Pierre Lecomte, a PhD candidate at Conservatoire National des Arts et M\u00e9tiers and Sherbrooke University. The core of the sound processing is written in Faust. The tools contain HOA encoders, decoders, binaural-filters, HOA signals transformations, spherical VU-Meter, etc. and can be compiled in various plug-ins format under Windows, Mac OSX, and Linux. The jury praised the quality and the usefulness of Ambitools: a really useful and technically advanced Faust app and an impressive technical achievement ! Check the demo . The committee was also very impressed by the quality of two other projects : Voice of Faust , a voice synthesizer/effects machine by Bart Brouns ( demo ). PMix , a graphical patcher, preset interpolator and JIT compiler for FAUST by Oliver Larkin ( demo ). Faust Student Software Competition to TouchVoices In parallel to the main competition, we introduced this year a junior competition: the Faust Student Software Competition , intended to promote small but interesting Faust applications, typically written as student projects. The student prize was awarded to TouchVoices (by Pierre-Adrien Th\u00e9o, RIM Master student at University Jean Monnet) a real-time web application allowing to capture, playback and transform sound loops. Here is a video of Pierre-Adrien Th\u00e9o during a performance with TouchVoices . A very close competitor was SuperBeatRepeater (by Vincent Rateau, of SuperDirt fame), a sample accurate beat repeater. Don't miss the demo ! 2016-08-30: FAUST book... The first FAUST book is Korean ! \u201c Sound Programming using FAUST \u201d, written by Jin-Wook Chae , an experienced audio developer and sound engineer (right) and Hyun-Hoo Jung (left), is the very first book ever published on FAUST. While the book is written in Korean, I was able to really appreciate the choice of the examples and the elegance as well as the high quality of the code. I am sure it will be an invaluable tool to promote FAUST in Korea among sound engineering, computer music students and more generally any person interested in sound programming. This book is for people desiring to produce musical instruments or sound processors. I have always been instructing my students that the ultimate importance is to discover interesting ideas about the sound. In spite of that, I have often relied on an unflattering response such as \"you may need to learn a programming language like C/C++...\" when a student asked for help with how to execute his/her ideas related to sound. Now I am pleased to recommend the use of FAUST to bring such ideas into execution. This is an easy self-study guide that can help to do just that. Now I can confidently tell anybody pursuing sound or electronic music that their exciting and brilliant idea about sound is what truly counts! So, really, how do we execute our ideas? Today I am introducing you to FAUST and to this book which you will find immensely helpful in terms of how to use FAUST to bring your fabulous ideas into reality. Jinwook Chae 2016-06-30: Faust interpreter A new 'interpreter' backend has been added in the faust2 development branch. It allows to execute Faust programs without using the LLVM dynamic compiler chain. Interpreter compilation chain The dynamic compilation chain allows developers to embed the Faust compiler technology directly in their application or plugins. Faust2 development branch uses an intermediate FIR representation (Faust Imperative Representation), which can be translated to several output languages. An LLVM backend has been previously developed to allows applications to compile a DSP source into executable code in memory, bypassing the external compiler requirement. In some specific situations, embedding the LLVM chain is not possible : for instance Apple does not allow to deploy dynamic compilers on iOS. Thus having an interpreter backend allows to get around this problem and still make Faust code run on those platforms. Interpreter backend The interpreter backend translates the FIR intermediate language into instructions for a virtual machine. A pure C++ interpreter for this instruction set has been implemented. Running and performances The interpreter backend translates the FIR intermediate language into bytecode for a virtual machine. It allows to run programs about 4 to 5 slower than native speed . Moreover this interpreter can be compiled in a special 'trace' mode to automatically detect various execution errors : invalid heap access, mathematical errors or warnings (division by zero, integer overloading....) which helps us to check the compiler semantic and code generation quality. Deployment for developers Given a Faust source code (as a file or a string), calling the createInterpreterDSPFactoryXXX function runs the compilation chain (Faust + interpreter) and generates the \u201cprototype\u201d of the class, as a interpreter-dsp-factory pointer. class interpreter_dsp_factory : public dsp_factory { public: /* Return Factory name */ std::string getName(); /* Return Factory SHA key */ std::string getSHAKey(); /* Return Factory expanded DSP code */ std::string getDSPCode(); /* Creates a new dsp instance */ dsp* createDSPInstance(); }; Note that the library keeps an internal cache of all allocated factories so that the compilation of the same DSP code, that is same source code and same set of 'normalized' (= sorted in a canonical order) compilations options, will return the same (reference counted) factory pointer. You will have to explicitly use deleteInterpreterDSPFactory to properly decrement the reference counter when the factory is no more needed. You can get a unique SHA1 key of the created factory using its getSHAKey method. Next, the createDSPInstance function, corresponding to the new className of C++, instantiates a interpreter-dsp pointer to be used through its interface, connected to the audio chain and controller interfaces. When finished, simply use delete to destroy the dsp instance. class interpreter_dsp : public dsp { public: void metadata(Meta* m); int getNumInputs(); int getNumOutputs(); void init(int samplingRate); void instanceInit(int samplingRate); dsp* clone(); void buildUserInterface(UI* inter); int getSampleRate(); void compute(int count, FAUSTFLOAT** input, FAUSTFLOAT** output); }; Since interpreter_dsp is a subclass of the dsp base class, an object of this type can be used with all already available audio and UI classes, in essence reusing all architecture files already developed for the static C++ class compilation scheme (like OSCUI, httpdUI interfaces etc.), see Developing a new architecture file . Saving/restoring the factory After the DSP factory has been compiled, your application or plugin may want to save/restore it in order to save Faust to interpreter bytecode compilation at next use. To get the internal factory compiled code, several functions are available: writeInterpreterDSPFactoryToMachine allows to get the interpreter bytecode as a string, writeInterpreterDSPFactoryToMachineFile allows to save the interpreter bytecode in a file, To re-create a DSP factory from a previously saved code, several functions are available: readInterpreterDSPFactoryFromMachine allows to create a DSP factory from a string containing the interpreter bytecode, readInterpreterDSPFactoryFromMachineFile allows to create a DSP factory from a file containing the interpreter bytecode. The complete API is available and documented in the installed faust/dsp/interpreter-dsp.h header. 2016-04-07: Web Audio API Faust and the Web Audio API (3) The Faust compiler can now directly be used in a Web page. Thanks to the Emscripten compiler, the Faust compiler itself can be compiled to asm.js JavaScript. This has been done by compiling the libfaust C++ library to the libfaust.js JavaScript library, that exports a unique entry point. Compiling DSP to JavaScript (asm.js) The libfaust.js exported function createAsmCDSPFactoryFromString(...) allows to create a DSP factory from a given DSP program as a source string and a set of compilations parameters, uses the Faust compiler asm.js backend, and produces the complete asm.js module and additional pure JavaScript methods as a string. Then calling JavaScript 'eval' function on this string compiles it in the browser. The dynamically created asm.js module and additional pure JavaScript methods can then be used. This internal code in then wrapped with additional JavaScript code. A DSP \u201cfactory\u201d will be created from the DSP source code with the following 'synchronous' code (if using the 'libfaust.js' library): var factory = faust.createDSPFactory(code, arguments); or possibly (if using the 'libfaustworker.js' library in the 'asynchronous' model): faust.createDSPFactory(code, arguments, callback); where 'code' is the DSP source as a string, and 'arguments' is an array of parameters to be given to the Faust compiler (like '-vec', '-vs 512'...), and 'callback' is a function taking the created 'factory' as argument. When no more used, you'll have to explicitly use the following code the deallocate the factory: faust.deleteDSPFactory(factory); Your application may want to save the already compiled factory as asm.js/JavaScript code to speed-up possible restore at later time: var machine_code = faust.writeDSPFactoryToMachine(factory); And restore the factory with the following code: var factory = faust.readDSPFactoryFromMachine(machine_code); Using DSP instances A fully working DSP \u201cinstance\u201d as a Web Audio node is then created with the code: var dsp = faust.createDSPInstance(factory, audio_context, buffer_size); When no more used, you'll have to explicitly use the following code to deallocate the instance: faust.deleteDSPInstance(dsp); This instance can be used like the statically compiled one, as previously described in this page . Polyphonic instruments Polyphonic instruments can be produced. For a given 'factory' the following code will create a 16 voices polyphonic instance: var dsp = faust.createPolyDSPInstance(factory, audio_context, buffer_size, 16); This instance can be used like the statically compiled one, as previously described in this page . Using Faust JavaScript library The Emscripten compiled Faust library can be used in two ways. Either using the 'libfaust.js' library: <script src=\"libfaust.js\"></script> <script src=\"webaudio-asm-wrapper.js\"></script> or if using worker mode with the following code which loads the 'libfaustworker.js' library: <script src=\"webaudio/webaudio-asm-worker-wrapper.js\"></script> 2016-02-05: Faust Award 2016 Faust Award 2016: deadline June 1, 2016 The Faust Open-Source Software Competition is intended to promote innovative high-quality free audio software developed with the Faust programming language, as well as development tools build around the Faust compiler itself.

Recently standardized WebAssembly language inherits from ideas experimented in both approaches, with the Mozilla vision finnally winning as Robert O'Callahan explains here . Coupled with the WebAudio API , running real-time audio code in the Web now appears to be an achievable goal. WebAssembly is a hot topic in the JavaScript ecosystem. The WebAudio community is eagerly waiting for the AudioWorklet specification, with its promised reduced latency and glitch-free audio rendering, to land in browser development versions, and be tested. Porting well established C/C++ codebase with Emscripten , like the Csound framework as an example, or using DSL languages like Faust, will then naturally beneficiate from improved and more stable performances. The Faust ecosystem already allows to generate static or dynamically compiled WebAssembly based WebAudio nodes . These nodes are still using the deprecated ScriptProcessor WebAudio interface. Premillinary work has been started to be ready as soon at the AudioWorklet model will be testable. In the meantime, work have been started using the WAVM , a standalone VM for WebAssembly, that can load both the standard binary and text wasm format, compiling it in native code using the LLVM chain (generating LLVM IR and compiling it on the fly to native code using LLVM JIT compiler), and running it at (near) native speed. Glue code to load and run Faust generated wasm modules has been written. Validation and benchmarking tools have been developed.

Other languages like Rust (using the mir2wasm tool) experiment direct WebAssembly generation. It seems clear that as WebAssembly specification and implementation stabilize, more and more languages will directly generate wasm to be deployed in browsers. The question of the quality of code generation at each step of the compilation chain will rapidly emerge. While WebAssembly is initially designed to run on the Web, it may be deployed in non Web environnement like nodejs , or even in standalone VM like WAVM . Thus WebAssembly becomes a portable binary format that can be used in a large variety of situations. This is especially of interest for a DSL language like Faust.","title":"Comparing the Faust C++, LLVM IR and wast/wasm backends"},{"location":"community/news/#faust-wastwasm-backend","text":"Faust wast/wasm backend directly produce WebAssembly code from the Faust internal FIR (Faust Imperative Representation) code.

Two generation models have been defined: in monophonic mode the wast/mast module internally allocates a memory block to be used for the DSP state (controllers, delays lines, waveforms...) as well as audio buffers. in polyphonic mode, the memory block will be allocated by the loader environnement. This block will typically be sized to contain all the needed voices for the polyphonic DSP. In both cases, a full description of the DSP state as a JSON string is generated in the module data segment (including memory indexes of all controllers). Loader code will get and decode this JSON description, and use whatever parts of the description it needs to run the DSP code.

Since its code can be easily adapted, one can estimate also what can be expected deploying wasm DSP modules in pure native environments , outside of the browser, where some audio specific optimizations may be considered. Measures done on a set of Faust DSP show that WebAssembly code still run slower than C++ or LLVM IR generated code in most cases, up to almost 66% slower in the less favorable examples. This value will typically be a bit worse when deploying in browsers, since float denormal protection code has to be used . Benchmarks in browser wasm runtime still need to be done to confirm or refine these findings. Comparing the Chrome , Firefox and WebKit browsers on OSX El Capitan shows that Chrome is currently the fastest engine in most cases, with Firefox and WebKit quite similar (with a slight plus for WebKit). Comparing the Chrome browser with native engines shows results from 4,8 times slower (filterBank.dsp), 2,8 times slower (sTunedBar6.dsp) up to much more favorable cases (karplus32.dsp). Note that filterBank.dsp example is a bit of a pathological case, since Chrome is significantly slower than Firefox and WebKit in this case, and filterBank.dsp uses a lot of pow(10, x) code that is rewritten an optimized as exp10(x) with the C++ backend path.","title":"Comments and Conclusion"},{"location":"community/news/#2017-08-18-faust-on-the-web","text":"","title":"2017-08-18: Faust on the Web"},{"location":"community/news/#deploying-faust-dsp-on-the-web","text":"EDIT : we are at the Web Audio conference 2017, and it appears that the way we currently extend the ScripProcessorNode with Faust code is not the Right Way...

The table is allocated as a class static pointer allocated using a custom memory allocator , which has the following propotype: struct dsp_memory_manager { virtual ~dsp_memory_manager() {} virtual void* allocate(size_t size) = 0; virtual void destroy(void* ptr) = 0; }; Taking the following Faust DSP example: process = (waveform {10,20,30,40,50,60,70}, %(7)~+(3) : rdtable), (waveform {1.1,2.2,3.3,4.4,5.5,6.6,7.7}, %(7)~+(3) : rdtable); Here is the generated code in default mode: ... int mydsp::itbl0[7]; float mydsp::ftbl0[7]; static void classInit(int samplingFreq) { SIG0 sig0; sig0.init(samplingFreq); sig0.fill(7,itbl0); SIG1 sig1; sig1.init(samplingFreq); sig1.fill(7,ftbl0); } virtual void init(int samplingFreq) { classInit(samplingFreq); instanceInit(samplingFreq); } virtual void instanceInit(int samplingFreq) { instanceConstants(samplingFreq); instanceResetUserInterface(); instanceClear(); } ... The two itbl0 and ftbl0 tables are static class arrays. They are filled in the classInit method. The architecture code will typically call the init method (which calls classInit ) on a given DSP, to allocate class related arrays and the DSP itself. If several DSP are going to be allocated, calling classInit only once then the instanceInit method on each allocated DSP is the way to go. In the new -mem mode, the generated C++ code is now: ... int* mydsp::itbl0 = 0; float* mydsp::ftbl0 = 0; dsp_memory_manager* mydsp::fManager = 0; static void classInit(int samplingFreq) { SIG0 sig0; itbl0 = static_cast<int*>(fManager->allocate(sizeof(int) * 7)); sig0.init(samplingFreq); sig0.fill(7,itbl0); SIG1 sig1; ftbl0 = static_cast<float*>(fManager->allocate(sizeof(float) * 7)); sig1.init(samplingFreq); sig1.fill(7,ftbl0); } static void classDestroy() { fManager->destroy(itbl0); fManager->destroy(ftbl0); } virtual void init(int samplingFreq) {} virtual void instanceInit(int samplingFreq) { instanceConstants(samplingFreq); instanceResetUserInterface(); instanceClear(); } ... The two itbl0 and ftbl0 tables are generated a class static pointers. The classInit method takes the additional dsp_memory_manager object used to allocate tables. A new classDestroy method is available to deallocate the tables. Finally the init method is now empty, since the architecure file is supposed to use the classInit/classDestroy method once to allocate and deallocate static tables, and the instanceInit method on each allocated DSP.","title":"Faust -mem option to control memory related code generation"},{"location":"community/news/#control-of-the-dsp-memory-allocation","text":"An architecture file can now define its custom memory manager by subclassing the dsp_memory_manager abstract base class, and implement the two required allocate and destroy methods.

A robot-probe is placed in a dark place, a cellar. It scans its surroundings with two lasers. The reliefs of the old walls, their imperfections, mold, appear thanks to the perfectly straight lines of the lasers. Its movements are synchronized with a sound program. From these very simple visual and sound choreographies are born an imaginary on its functioning and the origin of its presence. The spectator observes in a mirror a robot which observes and testifies. Does it communicate with other systems? Does it send information? Its energy is precious, like a heartbeat or a breath, it works in a segmented way with periods of silence. Likewise, his movements are slow and relentless.

Synthesizer-synthesizer This is a dual-course project for CS378 NLP and CS393P. The goal is to use language model guided program synthesis to synthesize Faust DSP code to ... automatically program synthesizers. Not guaranteed to work. In the slightest. Ambisonics in KMH studios and Lilla salen The general idea behind using ambisonics for diffusing sounds in a space is to, in the first stage, encode an audio signal to a representation of a sound field - a B-format signal. This B-format signal is independent of whatever speaker array the signal will later be diffused on. In the second stage the B-format signal is decoded to the layout of a particular speaker array. In between these two stages a number of transformations may be applied, but the sound source specification may conveniently be specified in the encoder. The decoders are written in Faust.

The model uses a few tricks to produce a Tambura-like sound, and should probably be referred to as a \"pseudo\" physical model, because it does not attempt to accurately recreate the physics of the string-bridge interaction. It includes a range of parameters selected to allow control of the qualities of the excitation/pluck, string behavior and sympathetic resonance. It can produce some beautiful evolving drones, which can vary from very synthetic to quite natural. The model can be tested here . drumbox drumbox is a fun and powerful drum synthesizer for your Android device. Start from a preset and tweak the sounds and appearance to make it your own.

Whetstone Transient Shaper A free, open source transient shaping audio plugin that operates on a specified frequency band. Whetstone will extract a certain frequency band based on a low cutoff and high cutoff that you choose, apply transient shaping to it, and then reintegrate the shaped band back into the original signal. This plugin is meant to be comparable to the excellent Spiff plugin in its core functionality, but lacks many of the nice features and polished UI. The DSP is coded in Faust . Reverb Trickery A free, open source audio plugin implementing various creative reverb effects, including octave-shifted, distorted, hi-pass/low-passed, gated, and narrowing reverb, coded in Faust . b259wf This is a model of the \"tibre\" circuit of the Buchla 259 Complex Wave Generator, made in Faust . The model follows the circuit modelling as seen on the paper Virtual Analog Buchkla 259 wavefolder , using 5 folds. The proposed 2-point BLAMP antialiasing method has been attempted for arbitrary sources as shown here , but it is not sufficient for high frequencies and/or more complex signals. Instead, filtering and light cubic nonlinearity distiorion has been used to round corners and for clipping. The user interface consists of the controls fold for the folding amount, offset for offseting the signal before folding, and lowpass as a final stage one-pole filtering to control the character (too much folding might introduce unwanted higher harmonics for certain signals). The final output is dc-blocked. string-machine This is a virtual-analog string ensemble synthesizer. The implementation is based on a digital model designed by Peter Whiting. The improvement of the model adds various abilities, in particular a virtual-analog emulation of the bucket brigade delay circuit. Most of the DSP code is developed using Faust. Three VST or LV2 are generated: string-machine , string-machine-chorus and string-machine-chorus-stereo . metaFx The metaFx is a control surface for continuous sound transformations in real time, just like the metaSurface64. Like metaSurface64 , it has both its own loop generator and a multi-effects FX engine, but its operation is different, especially for the management of plugin chains and pads. Each mixer on this surface can directly control the gain and the attached plug-ins. It is also possible to control the tracks of an external sequencer (Ardour or Reaper). To do this, the application uses OSC controllable modules that come from the Faust language library that is embedded in the application. Its interest lies in the construction of a parallel sound processing chain in the form of a graph.

Virtual Rhizome By Vincent Carinola . Virtual Rhizome responds to a proposal by Christophe Lebreton and Jean Geoffroy to compose a work for the original Smart Hand Computer system, developed at the GRAME-CNCM using the Faust language and allowing to play smartphones as an instrument. The work takes the form of a labyrinth, a kind of virtual architecture that could be compared to Borges' \"garden of branching paths\", within which the musician evolves by adapting his gestures to the constraints of different types of situations. Each situation is characterized by an autonomous functioning of the system, that the musician must apprehend in order to find the key allowing him to modify it and to move towards another situation. But in order to orientate himself well, he must create a mental representation of the structure of the work. The performer then becomes an explorer of a world that he unveils, but isn't that what he has always been? Virtual rhizome owes much to the availability and enthusiasm of Jean Geoffroy and Christophe Lebreton. It is amicably dedicated to them. SmartFaust SmartFaust is a concept of musical applications for smartphones. These applications have the particularity of only using the user's gestures and not by tapping on the device's screen. Made for iOS and Android, they can also use the motion sensors of these devices to make them real musical instruments. Smartfaust applications are based on the Faust (Functional Audio Stream) programming language developed by Grame over the last 15 years and recognized as a standard in the field of real-time signal processing for audio. The SmartFaust applications were first used for the creation of the pieces Mephisto (for drums and cell phone ensemble), Belzebuth (participative piece for public equipped with Smartphones), Iblis (for clarinet and cell phone ensemble) and B\u00e9lial (for harp and cell phone ensemble) written by the composer Xavier Garcia. From this same technology were later created the applications \"Geek Bagatelles\" (2016) and \"GameLan\" (2019). Download here: Android & iOS Trombone Simulator This simulator is a physical model of a trombone. Physical models of the lips, mouthpiece, slide, and bell are digitally simulated. The controls are listed at the top. The main controls are to move the cursor (or your finger on a touch device) left and right on the picture to adjust the embouchure, and up and down to extend and retract the slide. The diagonal colored lines are a guide to where the resonances are: playing over a resonance means that the embouchure and slide length are matched. Playing over white space means that one is between resonances and the note quality won't be as good. The big gray wedge on the upper right indicates that the resonances are very close together there. The vertical dashed lines indicate the rough locations of B-flat (thick lines) and F (thin lines). Other notes are unmarked, and likewise the slide positions. (Just like on a real trombone!) The off-key resonances (7th, 11th, 13th, and 14th) are marked in red. The g and f keys can be used to growl and flutter-tongue, respectively. The audio simulation is written in Faust, which conveniently compiles to WebAssembly and a Web Audio API wrapper. The overall approach used was a digital waveguide model, as described in J. O. Smith III's Digital Waveguide Theory. The lips and bell are adapted from F. Scott's masters thesis. Integrating 1-DoF force feedback interactions in self-contained DMIs By Mathias Kirkegaard .

The Striso board The Striso board is a very expressive music instrument which combines multidimensionally sensitive keys with an innovative note layout that helps understand the structures in music. The keys capture each subtle finger movement, which allows for levels of musical expression previously only known to acoustic instruments. Additionally, accents and sound effects can be added by shaking and moving the instrument as a whole. The internal sound is written in Faust, and is controlled directly by the signals from the keys and motion sensor. External synthesizers can be controlled using MPE MIDI, or using OSC which is easier to set up for Faust synthesizers. The firmware source code is released as open source. Live concatenative granular processing This algorithm addresses signal discontinuity and concatenation artefacts in real-time granular processing with rectangular windowing.

It offers equational definitions with pattern matching, full symbolic rewriting capabilities, dynamic typing, eager and lazy evaluation, lexical closures, built-in list and matrix support and an easy-to-use C interface. The interpreter uses LLVM as a backend to JIT-compile Pure programs to fast native code. It has been created by Albert Gr\u00e4f. pd-faust is a collection of Pd objects written using pd-pure which lets you run Faust programs inside Pd. It combines the functionality of pure-faust and faust2pd in a single package, and also features dynamic reloading of Faust plugins, automatic generation of controller GUIs and MIDI/OSC controller mappings, as well as OSC-based controller automation. It thus provides a complete solution for interactively developing Faust dsps in Pd. Guitarix An audio plug-in for guitar effects who's sound processing engine is written in Faust. moForte GeoShred An electric guitar app using physical modeling. Faust was used to implement its sound synthesis/processing engine. moForte PowerStomp An app implementing various guitar effects to be used on stage. moForte Guitar An app that can be used as an electric guitar and whose sound synthesis engine is implemented in Faust. FaustWorks FaustWorks is an IDE (Integrated Development Environment) for the Faust dsp programming language. You must have Faust installed to be able to use FaustWorks.
