class acoular.spectra.FFTSpectra¶

Bases: acoular.spectra.BaseSpectra, acoular.tprocess.TimeInOut

Provides the spectra of multichannel time data.

Returns Spectra per block over a Generator.

result()¶

Python generator that yields the output block-wise.

Parameters

numinteger

This parameter defines the size of the blocks to be yielded (i.e. the number of samples per block).

Returns

Samples in blocks of shape (numfreq, numchannels).

The last block may be shorter than num.
