# downmix

A Boolean value that indicates whether the framework mixes the channels instead of remapping.

## Declaration

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

## Discussion

Discussion This property defaults to false, indicating that the framework remaps the channels. When true, and channel remapping is necessary, the framework mixes the channels.
