well there’s this old blog from Stephan Bernsee using a “similar process” to the phase vocoder for frequency domain pitch shifting: http://blogs.zynaptiq.com/bernsee/pitch-shifting-using-the-ft/ http://blogs.zynaptiq.com/bernsee/repo/smbPitchShift.cpp not sure what your goal is, but at least in

i have some old MATLAB code that does the phase vocoder implementing time-scaling with a little extra thing that scales the sweep rate of sinusoids inside the frame.� it is a consequence of this very old paper i did for the IEEE WASPAA (Mohonk) in

Some time ago I posted some code in matlab, this is not real-time, you can see the basic math of an standard phase vocoder. https://dsp.stackexchange.com/questions/40101/audio-time-stretching-without-pitch-shifting/40367#40367 This code just change the time, you can pitch shift using a

Alex, A number of experienced DSP engineers have spent considerable time trying to help you understand the problem you're describing, yet it doesn't seem like you've made much progress. Your questions often seem to end up with asking folks to basically write your code for you. I don't want to be

You could also look at the code in csound on github. Has opcode for pitch sift and much else. ___ dupswapdrop: music-dsp mailing list music-dsp@music.columbia.edu https://lists.columbia.edu/mailman/listinfo/music-dsp
