*** ** * ** ***

Provides spatial audio playback for a sound field associated with an `https://developer.android.com/reference/androidx/xr/scenecore/Entity`.

It provides an `https://developer.android.com/reference/androidx/media3/exoplayer/audio/AudioOutputProvider` which can be used to configure an ExoPlayer.Builder instance for sound field audio playback. The characteristics of the sound field are defined by `https://developer.android.com/reference/androidx/xr/scenecore/SoundFieldAttributes`.

This component can only be attached to one `https://developer.android.com/reference/androidx/xr/scenecore/Entity` at a time.

```
public static final @NonNull SoundFieldAudioComponent create(@NonNull Session session, @NonNull SoundFieldAttributes attributes)
```

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

### getAudioOutputProvider

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

```
public final @NonNull AudioOutputProvider getAudioOutputProvider()
```

An `https://developer.android.com/reference/androidx/media3/exoplayer/audio/AudioOutputProvider` that can be used to configure an `https://developer.android.com/reference/androidx/media3/exoplayer/ExoPlayer.Builder` for [ambisonics](https://developer.android.com/develop/xr/jetpack-xr-sdk/add-spatial-audio#ambionics_example) audio playback. An `https://developer.android.com/reference/androidx/media3/exoplayer/audio/AudioOutputProvider` can only be bound with one Exoplayer instance and should not be re-used with other instances.

## Protected methods

### onAttach

```
protected boolean onAttach(@NonNull Entity entity)
```

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

This method is triggered when `https://developer.android.com/reference/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/androidx/xr/scenecore/Component#onAttach(androidx.xr.scenecore.Entity)`.

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

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

### onDetach

```
protected void onDetach(@NonNull Entity entity)
```

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

This method is triggered when `https://developer.android.com/reference/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/androidx/xr/scenecore/Component#onAttach(androidx.xr.scenecore.Entity)`.

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