# factoryPresets

A collection of presets provided by the audio unit’s developer.

```
var factoryPresets: [AUAudioUnitPreset]? { get }
```

## Discussion

A preset provides audio unit users with an easily-selectable, fine-tuned set of parameters defined by the developer.

This version 3 property is bridged to the version 2 `kAudioUnitProperty_FactoryPresets` API.
