- Sorry Jos,
-
- I had code to do some of those, but abandoned it when I came to work here.
- I wrote some myself and just twiddled the parameters. Mike Wang's suggestions
- should give you a good start there. (btw, band limiting gives a pretty good
- distortion effect). I can say, though, that you need to write the code VERY
- efficiently. If your sampling rate drops below ~30kHz, you'll lose the treble,
- and it sounds pretty bad.
-
- I know for a fact that there is some code out there, so try archie to look
- for it (I can't do that from here). Or post a question to comp.dsp
-
- Good Luck. Keep us posted if you find some good quality effects. I'll post
- mine if I can get them from my old accounts.
