Definition of Gammatone filter
A gammatone filter is a linear filter described by an impulse response that is the product of a gamma distribution and sinusoidal tone. It is a widely used model of auditory filters in the auditory system.
A gammatone response was originally proposed in 1972 as a description of revcor functions measured in the cochlear nucleus of cats.
