SteeringVector or derived object. Defaults to SteeringVector object.

numchannels = Delegate('grid', 'size')

Number of channels in output (=number of grid points).

weights = Trait('none', possible_weights, …

Spatial weighting function.

result(num=2048)

Python generator that yields the beamformer output block-wise.

Parameters
numinteger, defaults to 2048

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 (num, numchannels).

numchannels is usually very large. The last block may be shorter than num.
