Hello,

I've been using a lot the PVs family of opcodes to process sound
samples (doing time stretches, pitch shifting, smoothing, etc.) and
very often struggled trying to avoid "metallic" sounding results,
specially when doing time stretches (i.e. reading a PVX file with a
very slow pointer). One way I've been dealing with this is by using EQ
and reverb (tried also pvsmooth and pvsblur and didn't help much), but
I was wondering, are there any other techniques to avoid this? Is this
the result of analyzing using wrong parameters (I usually do: pvanal
-n 2048)? Do the PVS opcodes interpolate between windows? I've read in
some online articles about FFT in MAX/MSP and found mention to
interpolation as a way of increasing sound quality. Would this be a
way of avoiding it?

Thanks!

Hector
