# globalMetaParameters

A dictionary of metaparameters that all sound event assets share.

## Declaration

```swift
var globalMetaParameters: [String : PHASEMetaParameter] { get }
```

## Discussion

Discussion When you change a value for a metaparameter in this dictionary, every sound event attached to the metaparameter observes the change. The dictionary key is the identifier of the PHASEMetaParameterDefinition you pass into registerGlobalMetaParameter(metaParameterDefinition:). tip: To adjust a value for a single sound event, access the metaparameter through the metaParameters property instead.
