# listenerVectorOrientation

The listener’s vector orientation in the environment.

```
var listenerVectorOrientation: AVAudio3DVectorOrientation { get set }
```

## Discussion

The default orientation is with the listener looking directly along the negative z-axis (forward).

The node expresses a forward vector orientation as `(0, 0, -1)`, and an up vector as `(0, 1, 0)`.

Changing this property results in a corresponding change in the [`listenerAngularOrientation`](/documentation/AVFAudio/AVAudioEnvironmentNode/listenerAngularOrientation) property.
