Meta XR Audio SDK

What Meta XR Audio SDK is

Meta XR Audio SDK is a free development tool for adding spatial audio to immersive VR and MR applications. It uses HRTF-based object and ambisonic spatialization to help listeners locate sounds in three-dimensional space, and simulates room reflections and reverberation for spatialized audio. Meta documents integrations for Unity, Unreal Engine, FMOD and Wwise, with Windows and Android (Meta Quest) as runtime platforms. Its development targets include PCVR and Quest, Quest 2, Quest Pro, Quest 3 and Quest 3S. The Unreal plugin connects to the Unreal Audio Engine and runs independently of the Meta XR Plugin. Unity packages are available through the Meta Horizon Developer Center and Unity Asset Store. The SDK is free, with no free trial. Version 85.0 is the final release, and the project is on feature freeze with no further updates planned. Meta does not guarantee compatibility with future versions of supported engines or middleware. Bug reports will be acknowledged, but fixes are not guaranteed. The Wwise plugin is supported through Wwise Launcher and Audiokinetic; Meta’s Developer Center documentation for it will no longer be updated.

Who it suits

This SDK suits development teams creating immersive VR or MR experiences that need spatial audio, especially teams working with Unity, Unreal Engine, FMOD or Wwise. Its listed targets include PCVR and several Meta Quest headsets.

Getting started

1. Open the Meta XR Audio SDK page on the Meta Horizon Developer Center.
2. Choose the Unity package from the Meta Horizon Developer Center or Unity Asset Store, if using Unity.
3. Use the plugin for your documented engine or middleware integration.
4. For Wwise, use Wwise Launcher and Audiokinetic for plugin support.

Verdict

Choose Meta XR Audio SDK if your team needs spatial audio for a VR or MR project using one of its documented integrations. Look elsewhere if you need ongoing feature updates or guaranteed compatibility with future engine and middleware versions.
