# AVAudioEnvironmentOutputType

The output types for using with the automatic 3D mixing rendering algorithm.

## Declaration

```swift
enum AVAudioEnvironmentOutputType
```

## Overview

Overview The output type determines the rendering method for any input bus using AVAudio3DMixingRenderingAlgorithm.auto. To configure the output type, set outputType on AVAudioEnvironmentNode.
