Meta XR Audio SDK for Unreal Overview

Updated: Apr 15, 2026

Overview

This page introduces the resources and concepts for creating a compelling VR audio experience using the Unreal Audio Engine.
The Meta XR Audio SDK integrates with the Unreal Audio Engine through the MetaXRAudio plugin to provide HRTF-based spatialization, room acoustics simulation, and ambisonic decoding. The plugin is available as a separate download from the Meta developer website and operates independently of the Meta XR Plugin.
The sections below walk you through setting up an Unreal project to use the Meta XR Audio SDK plug-in in your game.
This guide focuses on the use of the Meta XR Audio SDK plug-in for Unreal but doesn’t attempt to be an Unreal tutorial. For additional information about Unreal Engine, see the Unreal website⁠.
By the end of this document, you’ll be able to:
  • Download the Meta XR Audio SDK.
  • Set the Meta XR Audio plug-in to spatialize audio.
  • Use the Meta XR Audio Source Settings to adjust spatialization, acoustics, gain boost, and reverb send.
  • Use a Meta XR Audio reverb submix preset and the Meta XR Audio Room Acoustic Properties component to change how reverberations are generated.
  • Adjust where the room acoustic originates from, size of the room, room materials, and clutter settings.
  • Play ambisonic audio.
