DESCRIPTION

pvread reads from a pvoc file and returns the frequency and amplitude
from a single anaylsis channel or bin. The returned values can be used
anywhere else in the csound instrument. For example, one can use them
as arguments to an oscillator to synthesize a single component from an
analyzed signal or a bank of pvreads can be used to resynthesize the
analyzed sound using additive synthesis by passing the frequency and
magnitude values to a bank of oscillators.

I do have some other files from RichardK on my portable, which is not here.
Will check over weekend.

Attached are the man pages for pvadd and pvoc that include the additions
of spectral extraction and amplitude gating. They have been used to
great effect here at the UW already, so I hope that others will be
able to now take advantage of these utilities.
