# stereo

A polar pattern that captures a stereo image of an audio source.

```
static let stereo: AVAudioSession.PolarPattern
```

## Discussion

If you select a data source with this polar pattern, call [`setPreferredInputOrientation(_:)`](/documentation/AVFAudio/AVAudioSession/setPreferredInputOrientation(_:)) on your audio session to ensure that left and right are correctly oriented in the captured audio.
