# PHASEGlobalMetaParameterAsset

A reference to a registered metaparameter that the app can share with multiple sound events or sources.

## Declaration

```swift
class PHASEGlobalMetaParameterAsset
```

## Overview

Overview The engine’s registerGlobalMetaParameter(metaParameterDefinition:) function returns an instance of this class for a parameter you register. Then, you access the actual metaparameter by using this class’s identifier as the key for metaparameter dictionary, for example, a sound event’s metaParameters or the asset registry’s globalMetaParameters. As an opaque derived object, this class adds no properties to the subclass.
