[PD] spectral mapping, anyone?

[peiman khosravi]

With spectral warping you can do any frequency-based manipulation,
depending on the transfer function. I have one for pd but it requires
Csound to be installed and a couple of other externals. See attached. On an
intel mac and with pd vanilla 4.5.3/4 this should just work out of the box
as long as you have csound 6 installed.
