Scriptnode pitch-shift a signal
-
Don't worry, I am using them myself too in some older projects, so I won't remove them entirely, but what I might do is to remove them by default and have a preprocessor macro that enables them so that people do not use them in new projects at some point.

This doubles the freq of a sign wav.

Yes I would love to be able to do this as well!
I've been wanting to program a shimmer reverb.
Probably quite ambitious. -

Plus, scriptnode now has two interpolating delay line nodes which will be of interest here.

@aaronventure
Thank you!
I haven't looked into FAUST yet, this is a good time to start -
https://github.com/christophhart/hise_tutorial/tree/master/PitchShifting
This uses two delay lines and fades between them. Note that the sound quality is far worse than what you expect from an industry standard pitch shifter (and the pitch shifter in Faust uses the same algorithm with only little sound quality improvement).
-
@Christoph-Hart so what would an industry standard pitch shifter do different, then? What's the catch?
-
@aaronventure I'm not 100% sure, but I guess it involves using a good timestretching library optimized for low latency that can handle live audio input.

@griffinboy hi mate! Faust is the way for me. Just google shimmer + faust + dsp
i.e https://github.com/azur1s/elysiera/blob/main/faust/dsp.dsp
