# AudioBufferResource

An audio resource that you load from an AVAudioBuffer.

## Declaration

```

## Overview

Overview Use the resource to create an AudioPlaybackController instance by calling an entity’s prepareAudio(_:) or playAudio(_:) function. The controller plays the audio from the location in space of the entity that created the controller.
