Description

This sample shows how to use the HAL's Audio Output Unit (AUHAL) for device input and output. The code demonstrates how to use Audio Unit and Audio Unit Graph APIs to handle the 'simplest' case of device input and output. The 'simple case' case in this example is when there is a single audio device that has both input and output. Apple's Built-in Audio device is an example of a device with input and output. Please note that this sample does not implement play thru with different input and output devices where the case is much more complex.
