log_cepstrum(data, fs, nc, p, n, w)[source]

Cepstrum of a signal.

Computes the cepstral coefficient on a logarithmic scale of the given data which can be windowed or not.

If data are windowed the analytic signal and the envelope of each window is returned.

  • data (ndarray) Data to make envelope of.
  • fs Sampling frequency in Hz.
  • nc number of cepstral coefficients.
  • p Number of filters in filterbank.
  • n Number of data windows.
