Hello,

If I understand you correctly, this is exactly what the GRM Tools plug-in Warp does. http://www.inagrm.com/warp

I have a version of this which I made with pd and csound, which I'm attaching. The FFT is done in Csound. To run it just install csound6 and then open up the patch. I've also included the externals with the patch, but they are built for osx so you'll need to replace them if you're on a different platform. I know that the csound~ external is running on osx, but I've never tried it on windows so...

If you want really precise control over which frequencies you're remapping then you need to change the pd patch a bit but it's just a question of converting bin number to frequency value, which is simple.

Best,

Peiman

Hi list , i need to iterate over all the frequency bins of a sound
getting each frequency and then i need to map that frequency to a
specific frequency .
Do anybody have tried something like this in pd?
which is the best way of doing this in pd? any hint?

cheers
