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.

oops, I messed up the names. sorry. Once more, with feeling:

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

But Alexandre, I'd also would be interested in stuff that can manipulate the spectrum.  
I also made a little graphic control to all the cross-synthesis objects in FFTease. if anyone is interested I can post.

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.

Hi, I'm Alexandre, I can send you stuff

cheers

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!
