Cepstrogram

plots the array of power cepstra computed on each partition of data.

uses partitions of length n.

uses partitions with offset d.

Cepstrogram[data,n,d,wfun]

applies a smoothing window wfun to each partition.

Cepstrogram[data,n,d,wfun,m]

pads partitions with zeros to length m prior to the computation of the transform.

Details and Options

Cepstrogram computes and plots an array of cepstra computed on partitions of data.
The power cepstrum for each partition is computed as the squared inverse Fourier transform of the log-power spectrum.
Use CepstrogramArray to get the numerical array of cepstra.
The partition length n and offset d can be expressed as an integer number (interpreted as number of samples) or as time or sample quantities.
Cepstrogram[list] uses partitions of length $n=2^Round[InterpretationBox[{log, _, DocumentationBuild`Utils`Private`Parenth[2]}, Log2, AutoDelete -> True](sqrt(m))+1]$ and offset , where m is Length[list].
In Cepstrogram[list,n,d,wfun], the smoothing window wfun can be specified using a window function that will be sampled between and or a list of length n. The default window is DirichletWindow, which effectively does no smoothing.
The data can be any of the following:
list arbitrary rank numerical array

audio an Audio or Sound object
For multichannel audio objects, the cepstrogram is computed over the sum of all channels.
Cepstrogram accepts all Graphics options with the following additions and changes:
