# kAudioFileStreamProperty_FormatList

To support formats such as AAC with SBR where an encoded data stream can be decoded to multiple destination formats, this property returns an array of `AudioFormatListItem` structures (declared in `AudioFormat.h`)—one for each of the destination formats. The default behavior is to return an `AudioFormatListItem` structure that has the same `AudioStreamBasicDescription` structure as that returned by the [`kAudioFileStreamProperty_DataFormat`](/documentation/AudioToolbox/kAudioFileStreamProperty_DataFormat) property.

```
var kAudioFileStreamProperty_FormatList: AudioFileStreamPropertyID { get }
```
