# supportedPolarPatterns

The set of directivity configurations supported by the data source.

```
var supportedPolarPatterns: [AVAudioSession.PolarPattern]? { get }
```

## Discussion

This property returns an array of one or more polar patterns, or <doc://com.apple.documentation/documentation/ObjectiveC/nil-227m0> if the data source doesn’t support directivity configuration. This feature is available only on the built-in microphone port for certain devices.
