# capabilities

The control capabilities this device supports.

## Declaration

```swift
let capabilities: [MediaDevice.Capability]
```

## Discussion

Discussion Each value in the array describes one operation the device supports, built from a MediaDevice.Capability, such as absoluteVolume(_:onChange:) or relativeVolume(onIncrement:onDecrement:). Pass an empty array if the device exposes no controllable capabilities.
