class acoular.spectra.FFTSpectra¶

Bases: BaseSpectra, 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.
