The easiest way to accomplish sample-precise starting/stopping is actually inlining the WAV recording into your script. E.g.
dac => Gain g => WvOut w => blackhole; "file.wav" => w.wavFilename; // temporary workaround to automatically close file on remove-shred null @=> w; // your code goes here SinOsc s => dac; 2::second => now; // end of code The WvOut will get shut down and closed whenever the script itself ends, leaving you with a file thats exactly the running length of the script. spencer On Thu, Jan 23, 2014 at 1:22 PM, Brian Sorahan <[email protected]>wrote: > Seems like the main script could signal an event when it is done (as > opposed to going into an infinite loop). > You could make a shared class that has a static Event member. > e.g. > > *Shared.ck* > -------------- > public class Shared { > static Event @ event; > } > new Event @=> Shared.event; > -------------- > > *main.ck <http://main.ck>* > ----------- > // send audio to dac > Shared.event.signal(); > ----------- > > *rec.ck <http://rec.ck>* > -------- > // record audio from dac > Shared.event => now; > -------- > > Then you just have to load Shared.ck before the other two scripts. > Hope that helps! > > Brian > > > On Thu, Jan 23, 2014 at 2:45 PM, Leonard Ritter < > [email protected]> wrote: > >> Hi there, >> >> I wrote this to Ge Wang on Twitter before but he's not been there >> since October, so I thought I'd better write here. >> >> I've used ChucK a few years ago and had quite some fun with it.
