| [Response](/engine/6000.5/script-reference/unityengine/audio/processorinstance/response.md) | [ProcessorInstance.Response.Handled](/engine/6000.5/script-reference/unityengine/audio/processorinstance/response/handled.md) if this [ProcessorInstance](/engine/6000.5/script-reference/unityengine/audio/processorinstance.md) acknowledged and processed the message, [ProcessorInstance.Response.Unhandled](/engine/6000.5/script-reference/unityengine/audio/processorinstance/response/unhandled.md) if not or ignored. |

### Remarks
