# kAudioFormatFlagIsNonInterleaved

A flag that indicates whether the samples for each channel or frame are continguously located, and whether the layout of the channels or frames is end-to-end.

```
var kAudioFormatFlagIsNonInterleaved: AudioFormatFlags { get }
```

## Discussion

This flag affects the use of the [`AudioStreamBasicDescription`](/documentation/CoreAudioTypes/AudioStreamBasicDescription) and [`AudioBufferList`](/documentation/CoreAudioTypes/AudioBufferList) structures.

Set this flag to indicate the samples for each channel are continguously located and the layout of the channels is end-to-end. Clear this flag to indicate the samples for each frame are continguously located and the layout of the frames is end-to-end.
