the same sample as before, rearranged and sequenced, transposed sound quality and latency aside, I think the idea has some potential https://soundcloud.com/traumlos_kalt/spectromat-test-4-01/s-7W2tR the second part is from Nancy Sinatras Summervine I am sorry it's all drenched in a resonant m

here an example at 22050 hz sample rate, FFT size 1024, smoothing for the spectral envelope 10 bins, and simple phase realignment: when amplitude is greater than last frames amplitude phase is set to original phase, otherwise to the accumulated phase of the time stretch didn't expect th

One thing I noticed is that it seems to sound better at 22050 Hz sample rate so I assume 1024 FFT size is too small and you should use 2048. I dont know if that is because the DC band is too high or if the bins are too broadband with 1024, or both? I assume with this and some phase realingment

Hmm. For me the "reply-to" in the original email header is set to "music-dsp @music.columbia.edu". If I hit Reply it goes to the list. I recall being annoyed by Reply going to the person and not the list. Why am I seeing something different? I am using GMail web client. And BTW, I set my default

I made a quick test, original first, then resynthesized with time stretch and pitch shift and corrected formants: https://soundcloud.com/traumlos_kalt/ft-resynth-test-1-01/s-7GCLk https://soundcloud.com/traumlos_kalt/ft-resynth-test-2-01/s-2OJ2H sounds quite phasey and gurgely I am using 1024
