# AVAudio3DMixing

A collection of properties that define 3D mixing properties.

## Declaration

```swift
protocol AVAudio3DMixing : NSObjectProtocol, Sendable
```

## Overview

Overview Only the AVAudioEnvironmentNode class implements these properties. important: The AVAudioMixing protocol adopts these properties. As a result, many classes inherit this protocol by adopting AVAudioMixing.
