# allowedAudioSpatializationFormats

The source audio channel layouts the player item supports for spatialization.

## Declaration

```swift
nonisolated var allowedAudioSpatializationFormats: AVAudioSpatializationFormats { get set }
```

## Discussion

Discussion Spatialization uses psychoacoustic methods to create a more immersive audio experience when playing content on specialized headphones and speaker arrangements. The default value for video content is monoStereoAndMultichannel, and multichannel for audio-only content. Your app can set a preferred spatialization format, but a user can change the audio spatialization behavior in Control Center. This property isn’t key-value observable. important: It’s incorrect to render binaural recordings with spatialization. Content tagged with a binaural channel layout ignores this property value.
