There are a few useful beat detection files in here.
Running chuck rundetect.ck will launch a ChucK program that plays a sample WAV file and "clicks" (and prints) where it detects a beat in that input. It works okay, but could probably use some tuning. The code for beat detection lives in beatDetect.ck
In practice, you can create an instance of the ListenForBeat class, chuck a UGen at its source property, and spork the listen(Event e) function. Whenever it thinks there's a beat, it broadcasts to that Event object to notify external code.
Running chuck runtap.ck launches a program that listens for keystrokes, and averages the time between strokes to find a beat. The main logic for that lives in beatTap.ck and beatTimer.ck.
I've expanded this code to also control a Parrot AR drone from ChucK, with a little help from Node.js. Now, you can do an ```npm install``, and then run:
node drone-osc.js &
chuck runosctest.ck
This will connect to the ARDrone (currently assuming it's your gateway), and then send a series of directives from ChucK to control it.
The next step is to make the drone dance to music. I plan to wire the beat detection up (and perhaps add some pitch detection), and use ChucK to plan a series of dance steps based on the music, to be executed by the drone, in real time.
