Capturing audio data

Once you've opened and configured a PCM capture device and prepared the PCM subchannel, you're ready to capture sound data.

For more information about this preparation, see “Handling PCM devices.”

There's a complete example of capturing audio data in the waverec.c example in the appendix. You may wish to compile and run the application now, and refer to the running code as you progress through this section.

This section includes:

• Selecting what to capture
• Capture states
• Receiving data from the PCM subchannel
• If the PCM subchannel stops during capture
• Stopping the capture
• Synchronizing with the PCM subchannel
