# isMeteringEnabled

A Boolean value that indicates whether you’ve enabled the recorder to generate audio-level metering data.

## Declaration

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

## Discussion

Discussion By default, the recorder doesn’t generate audio-level metering data. Because metering uses computing resources, enable it only if you intend to use it.
