# EffectInstance.CreationParameters

> Additional parameters and initialization state for creating an EffectInstance.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine.Audio](/engine/6000.7/script-reference/unityengine/audio.md)
* **Assembly:** UnityEngine.AudioModule

```csharp
public struct EffectInstance.CreationParameters
```

## Remarks

Currently mirrors the fields on [ProcessorInstance.CreationParameters](/engine/6000.7/script-reference/unityengine/audio/processorinstance/creationparameters.md), but exists as its own type so effect-only parameters, for example sidechain wiring, can be added later without touching the shared processor type.
