# PHASEAssetRegistry

A central repository of audio assets.

## Declaration

```swift
class PHASEAssetRegistry
```

## Overview

Overview This class manages audio by registering two types of assets throughout the app’s life cycle: When you’re done with a sound asset, call unregisterAsset(identifier:completion:) to free up its system resources.

## Topics

### Registering Sound Assets

- [unregisterAsset(identifier:completion:)](phase/phaseassetregistry/unregisterasset(identifier:completion:).md)

### Registering Sound Event Assets
