# kAudioFormatFlagIsSignedInteger

A flag that indicates whether the format is signed or unsigned integer.

```
var kAudioFormatFlagIsSignedInteger: AudioFormatFlags { get }
```

## Discussion

Set this flag to indicate the format is signed integer, and clear to indicate it’s unsigned integer. This flag is only valid if [`kAudioFormatFlagIsFloat`](/documentation/CoreAudioTypes/kAudioFormatFlagIsFloat) is clear.
