(snd-convolve sound response)
Convolves sound by response using a simple O(N x M) algorithm. The sound can be any length, but the response is computed and stored in a table. The required compuation time per sample and total space are proportional to the length of response. Use convolve instead
(convolve sound response)
Convolves two signals. The first can be any length, but the computation time per sample and the total space required are proportional to the length of response.

(setf rlen 100) ;length of response in samples
(setf response (snd-from-array 0 *sound-srate* (snd-fetch-array (snd-copy *track*) rlen rlen)))
(setf signal (extract-abs (/ rlen *sound-srate*) *stop* (cue *track*)))
