# AudioMixGroup

A group that manages the playback properties of multiple playing sounds.

## Declaration

```swift
struct AudioMixGroup
```

## Overview

Overview A mix group component manages the playback parameters for a collection of different AudioPlaybackController and AudioGeneratorController instances. Properties such as gain, fade(to:duration:), and speed are multiplicative with the parameters you set on the controller. You  associate audio resources to a mix group by setting the mixGroupName parameter in the resource’s configuration. For an example, see mixGroupName. Enable a mix group by adding it to an AudioMixGroupsComponent structure on an entity in the scene. The scene where the component belongs limits the scope of the mix group. var mixGroup = AudioMixGroup(name: "myMixGroup") entity.components.set(AudioMixGroupsComponent(mixGroups: [mixGroup]))
