Re: temporal resolution

[Regis Rossi Alves Faria <regis@xxxxxxxxxx>]

 
Hello,

auditory system is much more sensitive to modulations of any order than the visual system is;
during my studies with wavelet decomposition/reconstruction of audio/musical signals, it became very clear that spectral processing done in some
subbands produces several modulations in the audio signal, which are sensed as effects in the sound;
I wonder what kind of effects different delays applied to subbands would cause to the sound, causing the reconstruction to have easily recognized
distortion/modulations even when delays are very short.

regards,
Regis

Hi, I've posted 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 original? Regards, Dave.
