# inputParameters

An array of input parameters for the mix.

## Declaration

```swift
var inputParameters: [AVAudioMixInputParameters] { get }
```

## Discussion

Discussion The array contains instances of AVAudioMixInputParameters. note: An instance of AVAudioMixInputParameters isn’t required for each audio track that contributes to the mix. Audio for those without associated AVAudioMixInputParameters objects are included in the mix and processed according to the default behavior.
