Query: A Many to One Discrete Auditory Transform   A many to one discrete auditory transform is presented to map a sound signal
to a perceptually meaningful spectrum on the scale of human auditory filter
band widths (critical bands). A generalized inverse is constructed in closed
analytical form, preserving the band energy and band signal to noise ratio of
the input sound signal. The forward and inverse transforms can be implemented
in real time. Experiments on speech and music segments show that the inversion
gives a perceptually equivalent though mathematically different sound from the
input.
