Kamaelia docs : Kamaelia.Codec.Vorbis.AOAudioPlaybackAdaptor


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

class AOAudioPlaybackAdaptor(Axon.Component.component)

AOAudioPlaybackAdaptor() -> new AOAudioPlaybackAdaptor

Expects to recieve data from standard inbox, and plays it using libao. When it recieves a message on the control port: Sends a producerConsumed to its outbox. Then shutsdown.

Requires libao and pyao (python bindings)


A simple player:



  • control : If a message is received here, the component shutsdown
  • inbox : Any raw PCM encoded data recieved here is played through the default oss playback device


  • outbox : UNUSED
  • signal : When the component shutsdown, it sends a producerFinished message out this outbox

Methods defined here


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.


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


Performs the logic described above
