Hello... Use the SndBuf class to play a sample:
Here's the example code from ChucK docs*:
// the patch
SndBuf buf => dac;
// load the file
"../data/snare.wav" => buf.read;
// time loop
while( true )
0 => buf.pos;
Std.rand2f(.2,.9) => buf.gain;
Std.rand2f(.5,1.5) => buf.rate;
100::ms => now;
*But note, that code is changing the gain and rate of the sample
randomly - you would want a rate of 1.0 to just play the file at
Anyway, you can just plug SndBuf it into a filter, set the filter ...
and there you go!
Oh and use WvOut to record ChucK output to a file:
"This class provides output support for various audio file formats.
It also serves as a base class for "realtime" streaming
subclasses... WvOut writes samples to an audio file... WvOut currently
supports WAV, AIFF, AIFC, SND (AU), MAT-file (Matlab), and STK RAW
Hope that helps.
