[PD] spectral mapping, anyone?

Alexandre,Making harmonic sounds sound inharmonic can be down with spectral shifting. Try looking at Hilbert~ or at spec2_shift~ on extended.

But Jaime, I'd also would be interested in that. A few years ago I tried to replicate the technique that Trevor Wishart refers to as "Spectral Focusing", namely - one that moves the other way - from inharmonic to harmonic sonds, by moving from bins to partials (a little like FFTease's pvtune~, but moving bins to nearest matching partial).
I'm still looking for such an object. Does anyone have any suggestions? 
Zax.

These are older, but I understand E. Lyon might re-release them?

Hi,just looking for some ready to be used spectral mapping effects implemented in pd, anything available?Specifically, just a way to slightly remap harmonics to make pitched sounds inharmonic.
There is a paper by Alexandre http://www.uni-weimar.de/medien/wiki/images/Dissonance_Model_Toolbox_in_Pure_Data.pdf but I couldn't find the link to the sources.


Many thanks in advance!Josep m
