## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine.Audio](/engine/6000.5/script-reference/unityengine/audio.md)
* **Assembly:** UnityEngine.AudioModule
* **Implements:** [IDisposable](https://learn.microsoft.com/dotnet/api/system.idisposable)

```csharp
public struct ControlContext.Manual : IDisposable
```

## Remarks

This allows you to drive normally automatic functionality on scriptable processors contained within this [ControlContext](/engine/6000.5/script-reference/unityengine/audio/controlcontext.md). It's currently undefined behaviour to call any APIs from different threads simultaneously, so this can currently only be used for "offline usage".
