# anechoic

A reverb instance that applies no reverberation to spatial audio sources.

```
static let anechoic: Reverb
```

## Discussion> Warning: ``doc://com.apple.RealityKit/documentation/RealityKit/Reverb/anechoic`` will cause spatial audio sources to lose externalization,
> or the sense that an audio source is in a person’s space. Only use this case when when the immersive
> environment is abstract or otherwise unrealistic.
