This function computes the coefficients of an FIR or IIR gammatone digital filter [1]. Parameters: freqfloat Center frequency of the filter (expressed in the same units as fs ). ftype{‘fir’, ‘iir’} The type of filter the function generates. If ‘fir’, the function will generate an Nth order FIR gammatone filter. glob does nothing and dies https://qtproductsdirect.com
