Cepstrum is an auto-configurable DataProcessor which is used to compute a
specific cepstrum (for a target acoustic model) given the spectrum. The
Cepstrum is computed using a pipeline of front end components which are
selected, customized or ignored depending on the feat.params file which
characterizes the target acoustic model for which this cepstrum is computed.
A typical legacy MFCC Cepstrum will use a MelFrequencyFilterBank, followed
by a DiscreteCosineTransform. A typical denoised MFCC Cepstrum will use a
MelFrequencyFilterBank, followed by a Denoise component, followed by a
DiscreteCosineTransform2, followed by a Lifter component. The
MelFrequencyFilterBank parameters (numberFilters, minimumFrequency and
maximumFrequency) are auto-configured based on the values found in
feat.params.
