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.
