August'24: Kamaelia is in maintenance mode and will recieve periodic updates, about twice a year, primarily targeted around Python 3 and ecosystem compatibility. PRs are always welcome. Latest Release: 1.14.32 (2024/3/24)

Kamaelia.Audio.PyMedia.Output

Audio Playback using PyMedia

This component plays raw audio sent to its "inbox" inbox using the pymedia library.

Example Usage

Playing 8KHz 16 bit mono raw audio from a file:

Pipeline( RateControlledFileReader("recording.raw", readmode="bytes", rate=8000*2/8,
          Output(sample_rate=8000, channels=1, format="S16_LE"),
        ).run()

How does it work?

Output uses the PyMedia library to play back audio to the current audio playback device.

Send raw binary audio data strings to its "inbox" inbox.

This component will terminate if a shutdownMicroprocess or producerFinished message is sent to the "control" inbox. The message will be forwarded on out of the "signal" outbox just before termination.


Kamaelia.Audio.PyMedia.Output.Output

class Output(Axon.ThreadedComponent.threadedcomponent)

Output([sample_rate][,channels][,format]) -> new Output component.

Outputs (plays) raw audio data sent to its "inbox" inbox using the PyMedia library.

Keyword arguments:

  • sample_rate -- Sample rate in Hz (default = 44100)
  • channels -- Number of channels (default = 2)
  • format -- Sample format (default = "S16_LE")

Methods defined here

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.

__init__(self[, sample_rate][, channels][, format][, maximumLag])

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

main(self)
