SourceMixer¶

class acoular.sources.SourceMixer¶

Bases: 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.
