# SpatialAudioExperiences.AnchoringStrategy.scene(identifier:)

Anchor to the visual center of a particular UIScene.

## Declaration

```swift
case scene(identifier: String)
```

## Discussion

Discussion The sound tracks the center of the UIScene’s volume or window even as the user moves it around their space. Use the persistentIdentifier for a UIScene as the identifier. Configuring your sound with an unknown scene identifier causes the sound to receive a front anchoring strategy. If a sound starts with a known scene identifer but the scene becomes unknown later on, the sound remains aligned with the scene’s last-known location until the user executes a recenter gesture at which point it reverts to a front anchoring strategy. Using the UIScene identifier from an ImmersiveSpace results in the same behavior as a front anchoring strategy.
