# MLSoundClassifier.ModelParameters.FeatureExtractorType.audioFeaturePrint(type:revision:)

Represents the Audio Feature Print extractor.

```
case audioFeaturePrint(type: MLSoundClassifier.ModelParameters.FeaturePrintType = .sound, revision: Int = 1)
```

## Parameters

`type`

An Audio Feature Print extractor type.

`revision`

A version of the extractor you pass to `type`.

## Discussion

The case uses the newest version of [`MLSoundClassifier.ModelParameters.FeaturePrintType.sound`](/documentation/CreateML/MLSoundClassifier/ModelParameters-swift.struct/FeaturePrintType/sound)
if you don’t provide associated values for `type` and `revision`.
