To implement a dynamically controllable set of ChucK programs for the purpose of live performance, synchronization, and orchestration of previously recorded short duration loop-able audio files. As an example of performance, human grunting sounds recorded from the home-brew microphone are used to create images of the underworld in the CCRMA 16-channel Listening Room.

Thirty individual grunting sounds (10 short, 10 medium, and 10 long) were recorded into Audacity as a single stream. The files were then cut up into isolated events and saved with a numerical naming convection. Three folders were created to organize and store each class of recorded sounds (using folder names 1,2,3) as well. The naming convection allows for easy manipulation and access within the ChucK programing language.

Once all of the files are ready, the SndBuf command in ChucK can be used to playback the files. A random number generator can then be used to pick a random file among the folders and set a random playback rate (slower for lower grunts, faster for higher grunts).

For a complete orchestra or grunting sounds, a Using varying playback rates and
