the algorithm 'accumulates' energy from the
pvoc frame bins into a
'static' pvoc frame, thus the basic effect sounds a bit like an echo
or reverberation. (in fact i think it could be made to produce a
real nice reverb tail, with a _lot_ of tweaking though.)
of course this is combined with a decay mechanism so the stored energy
doesn't stay around forever. also, for some sound effects of the
stranger kind, Accumulate can also move the stored frequency
coefficients around, resulting in constant glissando of the 'sound
tail'.
This is pretty much what FreqTweak's Delay module does, although
I could not reproduce the exact Accumulate effect sound in FT upon
some basic tweaking. Of course, FT has absurdly more control :)
I've been waiting for someone to post a preset for FT that they
hand built to produce a good reverb tail, but it appears no one's
up to the challenge.....
The pitch scaling algorithm sounds quite similar to the one in
FT (which is basically the Sprengler algo from SWH's pitch scaler),
but Tim's sounds better, so I'm going to go code diving.
