# createParameter(withIdentifier:name:address:min:max:unit:unitName:flags:valueStrings:dependentParameters:)

Creates a single parameter object.

## Declaration

```swift
class func createParameter(withIdentifier identifier: String, name: String, address: AUParameterAddress, min: AUValue, max: AUValue, unit: AudioUnitParameterUnit, unitName: String?, flags: AudioUnitParameterOptions = [], valueStrings: [String]?, dependentParameters: [NSNumber]?) -> AUParameter
```

## Parameters

- `identifier`: The parameter’s non-localized, permanent name.
- `name`: The parameter’s localized name for display.
- `address`: The parameter’s address.
- `min`: The parameter’s minimum value.
- `max`: The parameter’s maximum value.
- `unit`: The parameter’s unit of measurement.
- `unitName`: The parameter’s localized unit name.
- `flags`: The parameter’s characteristic details.
- `valueStrings`: The parameter’s localized value strings.
