Re: [PD] Pitch Shift
Yes, it's not been released yet. I think she started a few threads on the forum (i don't think she's in the pd-list). Anyway do give Steve Harris' algorithm a shot, i remember trying it for shifting up one octave and it sounded great.

Re: [PD] Pitch Shift
Hi Have you seen the +pitchdelay~ from Tom Erbe and William Brent? I use it with +bubbler~ in rock-art2noise, so fine for my ears (perhaps not a good landmark :), to try Au plaisir Tad Alexandre Torres Porres a écrit : Thanks for the answers, I've seen the G.09 into an abstraction around and thought that th rjdj version could be it. It's also on the pdmtl package right? In which there's also a shifter based on the phase vocoder, anyway, the idea was to ask for something new. Thanks for the psola version julian, didn't know it, but as frank pointed, it may not suit me as I tried it and I prefer the phase vocoder version. And Pierre, in the link you sent it warns that it works best for small deviations, which can actually be good for me in one specific application, but not much on another unfortunately. I will try it, thanks! Anyway, I made a quick google on Stephen M. Sprengler's pitch scaler design and found no info on what the procedure is like :( By the way, I found this very interesting webpage about a pitchshifter~ object in Pd http://www.katjaas.nl/pitchshift/pitchshift.html But weirdly enough, I found no link to download it.

On Tue, 2 Aug 2011, Alexandre Torres Porres wrote: But the Pitch Shift example (G09.pitchshift.pd) sounds terrible That's exactly because of phase alignment when combining the granules of sound. You have two [vd~] and a cross-fader, and whenever the cross-fading happens, an harmonic might be partially cancelled, giving some kind of trémolo effect. So, it's another manifestation of the same problem we were talking about last time (freezing a spectrum...). And I know even less how to solve it. ___ | Mathieu Bouchard tél: +1.514.383.3801 Villeray, Montréal, QC ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Re: [PD] Pitch Shift
Different approaches suit different audio material and requirements. For very small shifts of a semitone or so either way the SSB modulation trick can still sound great.

Re: [PD] Pitch Shift
If you can get LADSPA plugins to work in Pd, there's also Steve Harris' Pitch Scaler (http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html#id1193). I tried it once, and it's the best sounding pitchshifter i've tried, with a decent latency I think.
