# prepareToPlay()

Prepares the player to play the sequence by prerolling all events.

## Declaration

```swift
func prepareToPlay()
```

## Discussion

Discussion The system automatically calls this method on playback, but calling it in advance minimizes the delay between calling play(_:) and the start of sound output.
