For examples and more explanations, see the module level docs.


class RawAudioMixer(Axon.ThreadedComponent.threadedcomponent)

RawAudioMixer([sample_rate][,channels][,format][,readThreshold][,bufferingLimit][,readInterval]) -> new RawAudioMixer component.

Mixes raw audio data from an unknown number of sources, that can change at any time. Audio data from each source is buffered until a minimum threshold amount, before it is included in the mix. The mixing operation is a simple addition. Values are not scaled down.

Send (uniqueSourceIdentifier, audioData) tuples to the "inbox" inbox and mixed audio data will be sent out of the "outbox" outbox.

Keyword arguments:

  • sample_rate -- The sample rate of the audio in Hz (default=8000)
  • channels -- Number of channels in the audio (default=1)
  • format -- Sample format of the audio (default="S16_LE")
  • readThreshold -- Duration to buffer audio before it starts being used in seconds (default=1.0)
  • bufferingLimit -- Maximum buffer size for each audio source in seconds (default=2.0)
  • readInterval -- Time between each output chunk in seconds (default=0.1)
