# audioEnvironmentNode

The 3D audio mixing node SceneKit uses for positional audio effects.

```
var audioEnvironmentNode: AVAudioEnvironmentNode { get }
```

## Discussion

SceneKit uses this audio node to spatialize sounds from [`SCNAudioPlayer`](/documentation/SceneKit/SCNAudioPlayer) objects attached to nodes in the scene. You can use this object in conjunction with the [`audioEngine`](/documentation/SceneKit/SCNSceneRenderer/audioEngine) property to rearrange the audio graph to add other, non-spatialized audio sources or mix in audio processing effects.
