Jesús, Someone should put this in the reference. The answer is (for stereo) to => the dac.left and dac.right to different left and right files. I use this to start recording: http://ravelite.org/code/chuck/stereo-rec.ck And this to stop recording: http://ravelite.org/code/chuck/stereo-rec-stop.ck Also, for multi-multi-channel, I explicitly make an array of channels and have my shreds play to the channels directly: http://ravelite.org/code/chuck/multi-rec.ck http://ravelite.org/code/chuck/multi-rec-stop.ck best, Graham On Tue, 25 Jul 2006, jesus gollonet wrote:

Hi all.

I've just published in my blog a little exercise in chuck. It's a reproduction of "clapping music" by steve reich.

http://www.jesusgollonet.com/blog/?p=133

Although they're in the blog post, I'll put the code and audio in the wiki if there is interest.

I have a question. How can i record stereo files in chuck? I haven't found anything in the reference.

Thanks a lot

best

Cool! Totally! For fun, here is a modified version that uses shreds and built-in glottal pops (ahh and ooo). If you want, play with the shift period and factor, or add a third clapper. --- // our patch sndbuf clapper1 => dac.left; sndbuf clapper2 => dac.right; // load built-in sounds "special:glot_ahh" => clapper1.read; "special:glot_ooo" => clapper2.read; // the full "clapping music" figure [.5, .5, 1, .5, 1, 1, .5, 1 ] @=> float seq[]; // length of quarter note .36::second => dur quarter; // how many measures per shift 3 => int shift_period; // how much to shift by (in quarter notes) .5 => float shift_factor; // one clapper fun void clap( sndbuf buffy, int max, float factor ) { int shifts; int count; // infinite time loop for( ; ; shifts++ ) { // one measure for( 0 => count; count < seq.cap(); count++ ) { // set gain seq[count] => buffy.gain; // clap! 0 => buffy.pos; // let time go by if( !max || shifts < max || count != (seq.cap() - 1) ) seq[count]::quarter => now; else { <<< "shift!!!", "" >>>; seq[count]*factor*quarter => now; 0 => shifts; } } } } // spork one clapper, shift every shift_period measures spork ~ clap( clapper1, shift_period, shift_factor ); // spork, no shift spork ~ clap( clapper2, 0, 0 ); // infinite time loop while( true ) 1::day => now; --- Best, Ge!
