# renderingAlgorithm

The type of rendering algorithm the mixer uses.

```
var renderingAlgorithm: AVAudio3DMixingRenderingAlgorithm { get set }
```

## Discussion

Depending on the current output format of the [`AVAudioEnvironmentNode`](/documentation/AVFAudio/AVAudioEnvironmentNode) instance, the system may only support a subset of the rendering algorithms. You can retrieve an array of valid rendering algorithms by calling the [`applicableRenderingAlgorithms`](/documentation/AVFAudio/AVAudioEnvironmentNode/applicableRenderingAlgorithms) function of the [`AVAudioEnvironmentNode`](/documentation/AVFAudio/AVAudioEnvironmentNode) instance.

The default rendering algorithm is [`AVAudio3DMixingRenderingAlgorithm.equalPowerPanning`](/documentation/AVFAudio/AVAudio3DMixingRenderingAlgorithm/equalPowerPanning). Only the [`AVAudioEnvironmentNode`](/documentation/AVFAudio/AVAudioEnvironmentNode) class implements this property.
