log_spaced_filterbank_matrix(p, n, fs, w)[source]

Matrix for a log-spaced filterbank.

Computes a matrix containing the filterbank amplitudes for a log-spaced filterbank.

  • p Number of filters in filterbank.
  • n Length of fft.
  • fs Sampling frequency in Hz.
  • w Window function.

xx, yy, zz - Matrix containing the filterbank amplitudes, Lowest fft bin with a non-zero coefficient, Highest fft bin with a non-zero coefficient.
