Re: temporal resolution
Title: Re: temporal resolution
Arai & Greenberg (1998) studied speech intelligibility in
samples in which spectral slices had undergone temporal jitter of this
general kind. My recollection is that asynchronies up to (and
sometimes exceeding) 200 ms could support 50%-correct word
recognition. "Correct word recognition" is, of course,
not the same thing as "perceptual equivalence". My
point is only that the Arai & Greenberg article might be a good
place to start looking for the evidence you need. I hope that
this helps. All good wishes,

intelligibility in the presence of cross-channel spectral asynchrony.

this message to the music-dsp list so apologies to anyone who
recieves it twice (should have posted it here in the first place since
its more appropriate).
Consider the case where an audio signal
is filtered into subbands and each subband is passed through a delay
(of different duration for each subband) before recombination of
subbands to produce a new signal. What would be the maximum
permissible difference between the maximum and minimum delays so that
the new signal is perceptually equivalent to the
