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

## Declaration

static let stereo: AVAudioSession.PolarPattern
```

## Discussion

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