# availableCompatibleAudioFormats

The audio formats that this module is able to analyze, given its configuration.

## Declaration

```swift
var availableCompatibleAudioFormats: [AVAudioFormat] { get async }
```

## Discussion

Discussion If the audio format doesn’t matter, then there will be one format listed with a sample rate of kAudioStreamAnyRate and other values 0. If assets are necessary yet not installed on device, then the list will be empty. This property may be accessed before the module is added to the analyzer.
