Implementing a gammatone filter bank
WitrynaIt implements a fitlerbank of IIR gammatone filters as described in Slaney, M., 1993, “An Efficient Implementation of the Patterson-Holdsworth Auditory Filter Bank”. Apple Computer Technical Report #35. In this example, a white noise is filtered by a gammatone filterbank and the resulting cochleogram is plotted. WitrynaThe Gammatone Filter Bank block decomposes a signal by passing it through a bank of gammatone filters equally spaced on the equivalent rectangular bandwidth (ERB) …
