# parametersForOverview(withCount:)

Returns the audio unit’s most important parameters.

```
func parametersForOverview(withCount count: Int) -> [NSNumber]
```

## Parameters

`count`

The number of parameters to return.

## Return Value

An array of addresses representing the audio unit’s most important parameters.

## Discussion

This method allows a host to query an audio unit for a small number of its most important parameters, to be displayed in a compact generic view.

This version 3 method is partially bridged to the version 2 `kAudioUnitProperty_ParametersForOverview` API.
