Creates a time effect audio unit with the specified description.

```
init(audioComponentDescription: AudioComponentDescription)
```

## Parameters

`audioComponentDescription`

The description of the audio unit to create.

## Return Value

## Discussion

The `componentType` field of the description structure must be `kAudioUnitType_FormatConverter` (”`aufc`”); otherwise, the method raises an exception.
