# multichannelAudioMode

The multichannel audio mode to apply when recording audio.

```
var multichannelAudioMode: AVCaptureMultichannelAudioMode { get set }
```

## Discussion

This property only takes effect when the system routes audio through the built-in microphone. The system ignores the value when an external microphone is in use.

The default value is [`AVCaptureMultichannelAudioMode.none`](/documentation/AVFoundation/AVCaptureMultichannelAudioMode/none), which indicates to use single channel audio recording.
