WebNov 4, 2024 · A gammatone filter has an impulse response that is a sine wave multiplied by a gamma distribution function. It is a common approach to modelling the auditory system. The gammatone filterbank approach can be considered analogous (but not equivalent) to a discrete Fourier transform where the frequency axis is logarithmic.
