Timeliner

A browser for long audio recordings.

1-minute example video.

6-page description.

News story giving historical context.

Building on Ubuntu 10.04 or 12.04

sudo apt-get install g++ freeglut3-dev gsl-bin libgsl0-dev libglm-dev libsndfile1-dev libxi-dev libxmu-dev libasound2-dev audiofile-tools libglew-dev libpng12-dev

Install HTK 3.4.1. (For audio files exceeding 2 GB on 64-bit Linux: after running HTK's ./configure, but before running make, in all of HTK's subdiectories' Makefiles, remove -m32 from the CFLAGS definitions.)

Optionally install QuickNet.

make

Building on Windows

Install libsndfile. Use the 32-bit version, not the 64-bit one.

Install Microsoft Visual Studio Express 2012 for Windows Desktop.

Install freeglut, using Visual Studio.

  • Build as Win32, not x64 (see the Configuration Manager).
  • Build all 4 configurations: debug and release, static and non-static.

Install GLM.

  • Copy the folder glm (that contains glm.hpp, etc.) somewhere.

Install HTK 3.4.1. Corrected instructions:

  • Don't bother adding "C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin" to your PATH.
  • Instead of VCVARS32, run "C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\vcvars32.bat" (note the double quotes).
  • Ignore every .c file's compiler warnings D9035, D9036, and D9002. HCopy will still run.
  • Either add to your PATH the folder bin.win32, wherever you'd put that, or copy bin.win32/HCopy.exe to some folder on your PATH.

Install libpng.

Install zlib.

Start Visual Studio. Open timeliner\timeliner.sln. Within that solution, in each project, rightclick Properties;

  • For Configuration, choose All Configurations.
    • In VC++ Directories, add the Include Directory and Library Directory to where you installed libsndfile, freeglut, GLM, libpng, and zlib. (This is smarter than copying *.lib and *.h into the Timeliner project.)
      (Beware the different directories Program Files and Program Files (x86).)
    • In Debugging, for Command Arguments specify:
      • for project timeliner_pre, a marshal dir and a config file, e.g. example\stereo\marshal example\stereo\config.txt.
      • for project timeliner, a marshal dir, e.g. example\stereo\marshal.

Build the debug and/or release versions of projects timeliner_pre and timeliner.

Copy freeglut.dll and libsndfile-1.dll to timeliner\Debug and timeliner\Release.

Run the projects timeliner_pre and timeliner (hit Ctrl+F5).

(Audio is built on RtAudio, which uses Windows' own DirectSound.)

How to adjust

The maximum width of a vector of values in a node of the agglomerative cache is the compile-time constant CQuartet_widthMax in timeliner_cache.h.
