I started to experiment with morphing, using the Tau editor. Super convenient, and gives great results, even going from inharmonic spectra to harmonic.
I was curious about the analysis process, and couldn't find much info in the manual. I understand it does morphing by morphing pitch, amp and formant envelopes from one sound to the other. But is there any FFT analysis / resynthesis happening behind that?
Same question with Morph1DGrainCloud: is the morphing process a linear interpolation between grains of one sound to another?
More generally, what's your experience and successes with morphing?.. Tau vs. Spectral analysis vs. graincloud morphing.
