# PHASESpatializationMode.automatic

A mode that indicates that the framework chooses the spatialization mode.

```
case automatic
```

## Discussion

This setting instructs the framework to automatically set a mode that determines how PHASE positions and orients sound in 3D space. The framework chooses a mode based on the output device:

- `PHASESpatializationMode.binaural`: Headphones (Bluetooth or line output) and the internal speakers of supported Mac or iOS devices.
- `PHASESpatializationMode.channelBased`: External speakers with 2 or more channels.
