public struct AudioFormat
```

## Remarks

An [AudioFormat](/engine/6000.7/script-reference/unityengine/audio/audioformat.md) provides information such as sample rate, speaker setup, and buffer size. It is used by types such as [ControlContext](/engine/6000.7/script-reference/unityengine/audio/controlcontext.md) and [ProcessorInstance](/engine/6000.7/script-reference/unityengine/audio/processorinstance.md).
