yes,i find it also not an absurd question. I had build a loop machine, and i did want to phase cancel the sound is coming out of the speakers to be able recording and play again new stuff over that loop in "realtime" (overdubbing). But as far as i understand it is a really complex thing to do so as chuck allready mentioned. But someone build allready a kind of "feedback canceller" or is it simply not possible in the real world?
it's possible: http://en.wikipedia.org/wiki/Echo_cancellation
but I'm no expert at this...
perhaps there's some reusable code of asterisk or other telephony software with implementations of cancellation mechanisms someone could...
