Hi all!  I'm a new user of CSound and a new member of the list.  This
would be an interesting development--sort of like some of the stuff the
Kurzweill K2500XS can do.  BTW, I have the Turtle Beach Multisound
Pinnacle, and the audio quality is amazing (at least, in my setup), and I
believe that there is also a set of linux drivers available (I think that
they are at http://modoc.wpi.edu/tbeach/).  Well, that's all for now.

Dear illegal art,

sounds like a great project. I do a lot of work with Csound-processed audio
files and would love to be on your mailing list.

Thanks,
John

Well, in the analog days, a technique for underwater sound was to 
modulate a low pass filter cutoff (with some resonance, probably) both
below and above the fundamental of the audio input, perhaps by a
sample&hold.

There are probably much more interesting techniques in the digital
domain. It actually sounds like an interesting problem.  (What is the
underlying physical model)
