Computes the averaged cepstrum smoothed amplitude spectrum, via the inverse transform of the lowpass filtered cepstrum.
- coefs.
- Number of cepstrum coefficients which should be used to compute the smoothed spectrum. If this value is set to zero the number of cepstrum coefficients is set to: lfrm0.5 (with: lfrm = frame length in samples).
- offset
- Amplitude offset to be added to the smoothed spectrum.
- sp – cp (LOFAR)
- Compute and display the difference "spectrum – smoothed spectrum".
