April 2024 - This site, and Kamaelia are being updated. There is significant work needed, and PRs are welcome.
For examples and more explanations, see the module level docs.
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)

Warning!
You should be using the inbox/outbox interface, not these methods
(except construction). This documentation is designed as a roadmap as to
their functionalilty for maintainers and new component developers.
