The mel-cepstrum is defined on the warped frequency scale which
is given as the phase response of the first-order all-pass
function. Note that we set the frequency warping parameter
"alpha" in such a way that the phase response provides a good
approximation to the auditory frequency scale, e.g., mel-scale.
