BUILT-IN MATHEMATICA SYMBOL
SpectrogramArray
SpectrogramArray[list]
returns the spectrogram data of list.
SpectrogramArray[list, n]
uses partitions of length n.
SpectrogramArray[list, n, d]
uses partitions with offset d.
SpectrogramArray[list, n, d, wfun]
applies a smoothing window wfun to each partition.
Details and Options
- SpectrogramArray[list] returns the discrete Fourier transform of partitions of list.
- SpectrogramArray[list] uses partitions of length
and offset Round[
], where m is Length[list]. - If necessary, fixed padding is used on the right to make all the partitions the same size.
- In SpectrogramArray[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. - SpectrogramArray also works with SampledSoundList. For multichannel sound objects, the spectrogram is computed over the sum of all channels.
- SpectrogramArray accepts the FourierParameters option. The default setting is FourierParameters->{1, -1}.
