For "I am sitting in a room", I suggest you just use a delay; no internal feedback loop, just adc => delay => dac. Of course, if you want to record it as well, that is separate, and you'll probably also want to have a quick way of dropping adc gain (maybe on your preamp rather than in software) for when the feedback gets out of hand.
I read this thread and downloaded the original Lucier piece, which I found quite haunting. And then I could achieve a similar effect by simply changing the delay.ck example time lapse to 75 seconds: // patch adc => DelayL delay => dac; // set delay parameters 75::second => delay.max => delay.delay; // infinite time loop while( true ) 1::second => now; I'm a novice at sound/ChucK. So I guess that my room is resonating, and the drone that develops after 10-15 minutes is my speakers screaming at the mic. There are still some bizarre patterns though. Sounds of my shower etc. It's all quite surreal. Now I want to control this drone in some way because it gets quite monotonous, and I want to trigger some mp3 cuts when certain frequencies are encountered. I'll figure all this out, just sharing my experience. I also want to keep the final code less than 100 lines. Lets see! Very excited now. ------- -.- 1/f ))) --. ------- ... http://www.algomantra.com
