      Added a bank of 20 Gammetone filters, of 512 coefficients and sampling rate 44100hz, covering the frequency range 100-20000hz. Filters are windowed with the right half of a Hann window (of size 1024).

      Added a script to generate Gammatone FIR filters in .wav format, by using the library from Bingo Todd.
      Because a rectangular windowing produces ringing in the magnitude of the frequency response at low frequencies when the filter have ~512 coefficients, we apply a windowing of the filter impulse response in order to improve the filter quality. After windowing, a normalization is applied to restore the correct magnitude peak in the frequency response domain.
