# kAudioFileGlobalInfo_AvailableStreamDescriptionsForFormat

An array of audio stream basic description structures, which contain all the formats for a particular file type and format ID.

```
var kAudioFileGlobalInfo_AvailableStreamDescriptionsForFormat: AudioFilePropertyID { get }
```

## Discussion

The audio stream basic description structures have the following fields filled in: `mFormatID`, `mFormatFlags`, and `mBitsPerChannel` for writing new files. When accessing this property, provide a pointer, in the `inSpecifier` parameter, to an audio file type and format ID structure.
