pyampact.speechDescriptorsUtils.compute_spectral_spread(S, freqs)[source]

Compute spectral spread

Parameters:

  • S (ndarray) – magnitude spectrum

  • freqs (array) – frequency axis in Hz (freq_bins,)

Returns:

  • rp_ms (float) – recurrence period in ms

  • rpde (float) – normalized entropy of recurrence-period distribution
