# reverbBlend

A value that controls the blend of dry and reverb processed audio.

```
var reverbBlend: Float { get set }
```

## Discussion

This property controls the amount of the source’s audio that the [`AVAudioEnvironmentNode`](/documentation/AVFAudio/AVAudioEnvironmentNode) instance processes. A value of `0.5` results in an equal blend of dry and processed (wet) audio.

The default is `0.0`, and the range of valid values is `0.0` (completely dry) to `1.0` (completely wet). Only the [`AVAudioEnvironmentNode`](/documentation/AVFAudio/AVAudioEnvironmentNode) class implements this property.
