# preferredVolume

The track’s volume preference for playing its audible media.

## Declaration

```swift
static var preferredVolume: AVAsyncProperty<Root, Float> { get }
```

## Discussion

Discussion Use the load(_:isolation:) method to retrieve the property value. The preferred volume for an audio track is typically, but not always, 1.0. For nonaudible tracks, the value is 0.0.
