http://www.macalester.edu/~bsaylor/pvoc~-0.1.tar.gzpvoc~ is a phase vocoder external that provides independent control of
the playback position within the sound and pitch transposition via two
control inlets. It features adjustable phase locking and transient
de-smearing (given a list of manually determined transient positions).
In the future it may incorporate other enhancements, such as
independent processing of peaks and noise.

One advantage over an abstraction-based PV is that the delay of the
output doesn’t depend on the FFT size, so it’s more immediately
responsive. Hopefully it’s also a little more efficient, but I haven’t
tested it yet for efficiency.

pvoc~ requires FFTW 3. It has not been tested yet on anything other
than Debian unstable on Intel. Here’s a direct URL, but it will only
be there temporarily because I’m graduating soon and losing my web
space..
