This is the version of the IIR gammatone used in Slaney's Auditory toolbox. The original verison as described in Apple Tech. Report #35 has a problem with the high-order coefficients at low centre frequencies and high sample rates. Since it is important that AIM-C can deal with these cases (for example for the Gaussian features), I've reiplemeted Slaney's alternative version which uses a cascade of four second-order filters in place of the eighth-order filter.
The original source code for these functions in AIM-C can be found at: http://code.google.com/p/aimc/
