I use 2^octave * SR/FFTsize -> toERBscale -> * log2(FFTsize)/42 as a
scaling factor for the windows.
Means the window of the top octave is about 367 samples at 44100 SR -
does that seem right?
ok this was wrong...
it should be just windowsize = 1/bandwidthERB
but when I use windowsize = 1/bandwitdhERB I get windows that are too
the phase vocoder, for instance for the lowest band I get
bandwidthERB (~10Hz) ~= 26 Hz bandwidth, ~ 1705 samples window length
This gives too much modulation or too much bandwidth by the window, even
if I double this.
(I know that ERB does not go to 10 Hz but the same is true for all bands.)
So, what am I doing wrong here?
