A common sequence of operations in the early stages of most sensory systems is a multiscale transform followed by a compressive nonlinearity. The authors explore the contribution of these operations to the formation of robust and perceptually significant representation in the early auditory system. It is shown that auditory representation of the acoustic spectrum is effectively a self-normalized spectral analysis, i.e., the auditory system computes a spectrum divided by a smoothed version of… CONTINUE READING
