Hi folks, so, what are the options out there for Pitch Shifting?
I usually use the Phase Vocoder, but there is an inevitable little bit of delay and the buffer issue.
But the Pitch Shift example (G09.pitchshift.pd) sounds terrible next to the phase vocoder, I think. And, well, basically I'd like to keep the same length, just like the phase vocoder, so what do you say?
thanks
what about e_pitchshift (from RjDj)?

do you know what is it based on?
It's like a didactical doubt as well, you know...

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.

That's the G09 example patch transformed to an abstraction.

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.

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.
