Example Usage

Recording telephone quality audio to a file:

Pipeline( Input(sample_rate=8000, channels=1, format="S16_LE"),
          SimpleFileWriter("recording.raw"),
        ).run()

How does it work?

Input uses the PyMedia library to capture audio from the currently selected audio capture device.

It outputs to its "outbox" outbox raw binary audio data in strings.

This component supports sending to a size limited inbox. If the size limited inbox is full, this component will pause until it is able to send out the data.

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.

class Input(Axon.ThreadedComponent.threadedcomponent)

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

Captures audio using the PyMedia library and sends the raw audio data out of its "outbox" outbox.

Keyword arguments:

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