Very good idea. However I'm neither Bill, nor William :D
Concerning dumbtts I guess the answer is clear. BTW, I have a couple
of patches for it.

why? since it does nothing, why do you need it in ivona.c?

yes, actually the problem with -100...0...100 that it does not tell
you for the different modules whether
100 is 3X or just 1.5X. And here sonic can help and normalize 100 for
all e.g. to the 3X.

yes, something like
AudioTrack * spd_audio_effect(AudioTrack *track,...)
since you need an output as well.
