Thanks for the ideas!

I've done some more work and have made a "real cepstrum", and morphing two signals sounds amazing and crisp, WAY clearer than spectral morphing.

I'm looking at keeping it as vanilla as possible, but I still apprecaite the reccomendations.

I'll keep my eyes on this thread over the weekend, see if anyone else has anything.

Hi people,

I've been looking at paper after paper, trying to get my head around Cepstral processing, Liftering, Quefrencies and what not, but I just can't seem to get past the "first stage"

I understand Spectral processing quite well, and how to theoretically produce a cepstrum, (windowing~ rfft~, cartopol~ log~ rfft~ (roughly) = huzzah, the cepstrum) and return back to a time-domain signal. And yet, I can find nothing about processing audio in meaninful ways using the cepstrum (Formant shifting being one of my goals).

I've tried splitting the real cepstrum into sections with basic array-filtering, shifting and what not, and at this point i'm throwing stuff at the wall to see what sticks.

I'd rather not rely on externals such as TimbreID, while they are handy for analysis, it's hard to use these objects in terms of an actual audio "effect", they're more for indexing (at least, as far as I know)

If anyone has any Ideas, patches or perhaps even more papers for me to explore, I'd greatly appreciate it.

Cheers, Ewan

@whale-av
managed to fix it, i was attempting to use "startx /pd /mypdpatch.pd" and have kiosk do the full-screening for me. My mistake was not realising that the pd console was the one X was attaching itself to.
Silly issue on my part.
Appreciate the support none the less, perhaps @mbbaker has a different issue.

Exactly the same issue here, looking for any kind of alternative or fix to this.
