# multichannelAudioMode

The multichannel audio mode to apply when recording audio.

## Declaration

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

## Discussion

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, which indicates to use single channel audio recording.
