*** ** * ** ***

A Component that provides positional spatial audio playback for an `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity`.

It provides an `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/audio/AudioOutputProvider` which can be used to configure an `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/ExoPlayer.Builder` instance for positional audio playback.

This component can only be attached to one `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity` at a time. If the component is detached from an `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity`, the audio will become head-locked.

## Public companion functions

### create

Added in [1.0.0](https://developer.android.com/jetpack/androidx/releases/xr-scenecore#1.0.0)

```
fun create(session: Session, params: PointSourceParams): PositionalAudioComponent
```

Creates a `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/PositionalAudioComponent` for the given `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/PositionalAudioComponent.Companion#create(androidx.xr.runtime.Session,androidx.xr.scenecore.PointSourceParams)` and initializes it with the provided `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/PositionalAudioComponent.Companion#create(androidx.xr.runtime.Session,androidx.xr.scenecore.PointSourceParams)`.

## Protected functions

### onAttach

```
protected open fun onAttach(entity: Entity): Boolean
```

Called by the framework when this component is being added to an `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity`.

This method is triggered when `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity#addComponent(androidx.xr.scenecore.Component)` is invoked. Implementations should override this method to perform setup logic or to validate if the component is compatible with the provided `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Component#onAttach(androidx.xr.scenecore.Entity)`.

| Parameters |
|---|---|
| `entity: https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity` | The `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity` to which this component is being attached. |

| Returns |
|---|---|
| `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-boolean/index.html` | `true` if the component was successfully attached; `false` if the `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Component#onAttach(androidx.xr.scenecore.Entity)` does not support this component or if attachment failed. |

### onDetach

```
protected open fun onDetach(entity: Entity): Unit
```

Called by the framework when this component is being removed from an `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity`.

This method is triggered when `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity#removeComponent(androidx.xr.scenecore.Component)` is invoked. Implementations should override this method to release resources or undo any changes made during `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Component#onAttach(androidx.xr.scenecore.Entity)`.

| Parameters |
|---|---|
| `entity: https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity` | The `https://developer.android.com/reference/kotlin/androidx/xr/scenecore/Entity` from which this component is being detached. |

## Public properties

### audioOutputProvider

Added in [1.0.0](https://developer.android.com/jetpack/androidx/releases/xr-scenecore#1.0.0)

```
val audioOutputProvider: AudioOutputProvider
```

An `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/audio/AudioOutputProvider` that can be used to configure an `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/ExoPlayer.Builder` for positional audio playback. An `https://developer.android.com/reference/kotlin/androidx/media3/exoplayer/audio/AudioOutputProvider` can only be bound with one Exoplayer instance and should not be re-used with other instances.

### pointSourceParams

Added in [1.0.0](https://developer.android.com/jetpack/androidx/releases/xr-scenecore#1.0.0)

```
var pointSourceParams: PointSourceParams
```
