Gammatone filters are a popular linear approximation to the filtering performed by the ear. This routine provides a simple wrapper for generating time-frequency surfaces based on a gammatone analysis, which can be used as a replacement for a conventional spectrogram. It also provides a fast approximation to this surface based on weighting the output of a conventional FFT. The underlying Gammatone filters are taken (with permission) from Malcolm Slaney's Auditory Toolbox, http://cobweb.ecn.purdue.edu/~malcolm/interval/1998-010/ .
