# changeReverb(to:duration:)

Creates an action that changes an audio node’s reverb to a new value.

```
class func changeReverb(to v: Float, duration: TimeInterval) -> SKAction
```

## Parameters

`v`

The new value for the reverb. The value should be between `0.0` and `1.0`, inclusive.

`duration`

The duration of the animation, in seconds.

## Return Value

A new action object.

## Discussion

When the action executes, the audio node’s reverb animates from its current value to its new value. For more information, see <doc://com.apple.documentation/documentation/AVFAudio/AVAudio3DMixing>.

This action is not reversible.
