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.
