Try this:
Code: Select all
(setq start-frequency 10) ; initial frequency in kHz
(setq end-frequency 1) ; final frequency in kHz
(let* ((ny (/ *sound-srate* 2))
(f1 (min (* start-frequency 1000) ny))
(f2 (min (* end-frequency 1000) ny)))
(lp (lp s (pwlv f1 1 f2))(pwlv f1 1 f2)))
The start and end frequencies must be less than half of the track sample rate.

Perfect, now I have to just fool around with it until it sounds right.
I have this little piece of code here that converts any waveform into non-aliased triangle (a little mis-shapen though), I'll try and fix it up and create one for saw and square.
(mult 2.0 (sum (snd-abs s) -0.5))
