SourceMixer¶

class acoular.sources.SourceMixer¶

Bases: acoular.tprocess.SamplesGenerator

Mixes the signals from several sources.

sources = List( Instance(SamplesGenerator, ()) )¶

List of SamplesGenerator objects to be mixed.

sample_freq = Property( depends_on=['sdigest'] )¶

Sampling frequency of the signal.

numchannels = Property( depends_on=['sdigest'] )¶

Number of channels.

numsamples = Property( depends_on=['sdigest'] )¶

Number of samples.

weights = CArray(desc="channel weights")¶

Amplitude weight(s) for the sources as array. If not set, all source signals are equally weighted. Must match the number of sources in sources.

validate_sources()¶

Validates if sources fit together.

result(num)¶

Python generator that yields the output block-wise. The outputs from the sources in the list are being added.

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 (num, numchannels).

The last block may be shorter than num.
