At least two programmes have come out of the discussion (one newly written, one
was previous research that was made available). Mine is real-time, and based
on a ring buffer as suggested by someone in this group. It requires a
Silicon Graphics Indigo to run (and X/Motif to compile). Ben Cox also
made a programme of his available, which works file->file rather than 
realtime (and hence is not restricted to one particular set of sound hardware).

Both sound good with small pitch-shifts, but start sounding strange with
larger ones.

I'm thinking of using some of Ben's technology to improve mine, but it's 
still on my "list of things to do".

Cheers,
