Esteemed colleagues:

I am interested in examining modulation spectrograms of speech constructed
from the outputs of an auditory-like filter bank (y-axis: frequency; x-axis:
modulation frequency; z-axis: darkness indicating level of modulation
spectrum). Does anyone have programs for making these? Matlab scripts
especially welcome.

Thank you for may help --

Yours - Stuart Rosen
