# enableRate

A Boolean value that indicates whether you can adjust the playback rate of the audio player.

## Declaration

```swift
var enableRate: Bool { get set }
```

## Discussion

Discussion To enable modifying the player’s rate, set this property to true after you create the player, but before you call prepareToPlay().
