I wanted to check before making my first CVS
PV_Add and PV_Mul lack SC code definition in FFT.sc
Trivial to sort out, but something I can safely commit
Can I also add pure PV_Convolution (since PV_MagMul
does nothing with phase, and PV_Mul isn't a proper
complex multiply), PV_Correlation, PV_Mag1Phase2
(simple cross synth using mag of first, phase of
second) at the same time?
A full complex multiply of two STFFTs is not really a convolution.
You'd want to have the FFT of one wave stored and complex multiply that
by a suitably zero padded input. The PV object base class does not
handle that case as is.
