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 this wo work but it seems to work
It seems to sound better to me, but still not as good as required:

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 and a better spectral
envelope
quality would be somewhat improved.
Unfortunately Reaktor isn't the right tool at all to test these
things, you have to hack around everything,
just changing the FFT size will probably waste a whole day, so I
probably won't investigate this further.
