# applicableRenderingAlgorithms

An array of rendering algorithms applicable to the environment node.

## Declaration

```swift
var applicableRenderingAlgorithms: [NSNumber] { get }
```

## Discussion

Discussion The AVAudioEnvironmentNode class supports several rendering algorithms for each input bus as AVAudio3DMixingRenderingAlgorithm defines. Depending on the current output format of the environment node, this method returns an immutable array of the applicable rendering algorithms. This subset of applicable rendering algorithms is important when you configure the environment node to a multichannel output format because only a subset of the algorithms render to all of the channels. Retrieve the applicable algorithms after a successful connection to the destination node through one of the AVAudioEngine connect methods.
