Details and Options
- Cepstrogram is an array of power cepstra computed on partitions of data.
- Power cepstrum for each partition is computed as the squared inverse Fourier transform of the log-power spectrum.
- Use Cepstrogram to directly plot the 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.
- CepstrogramArray [list] uses partitions of length and offset , where m is Length [list].
- In CepstrogramArray [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 1D numerical arrayvideo a Video object
- For multichannel audio objects, the cepstrogram is computed over the sum of all channels.
- The following options can be given:
-
