# AVAudio3DMixingRenderingAlgorithm

The types of rendering algorithms available per input bus of the environment node.

## Declaration

```swift
enum AVAudio3DMixingRenderingAlgorithm
```

## Overview

Overview The rendering algorithms differ in quality and CPU cost. AVAudio3DMixingRenderingAlgorithm.equalPowerPanning is the simplest panning algorithm and the least expensive computationally. When rendering to multichannel hardware, most of the rendering algorithms only render to channels 1 and 2, excluding AVAudio3DMixingRenderingAlgorithm.soundField and AVAudio3DMixingRenderingAlgorithm.auto.
