# AudioFileRegionFlags

Flags that specify a playback direction for an audio file region structure.

```
struct AudioFileRegionFlags
```

## Overview

You can set one or more of these flags. For example, if both `kAudioFileRegionFlag_LoopEnable` and `kAudioFileRegionFlag_PlayForward` are set, the region plays as a forward loop. If only  `kAudioFileRegionFlag_PlayForward` is set, the region is played forward once. if both `kAudioFileRegionFlag_PlayForward` and `kAudioFileRegionFlag_PlayBackward` are set, the region plays forward then backward, then forward.
