Audio Type: PCM, 16 bit

Audio Channels: 1

To minimize latency, pre-enable the apps audio session and request very short buffer durations. Start the RemoteIO Audio Unit output running with the output callback polling a circular buffer, otherwise playing a bit of silence. Then format (resample if needed) and store samples of the wave file, as any portions of the wave file are received, in the circular buffer.
