Set Up the Oculus Audio Loudness Meter
Updated: Sep 14, 2023
End-of-Life Notice for Oculus Spatializer Plugin
The Oculus Spatializer Plugin has been replaced by the Meta XR Audio SDK and is now in end-of-life stage. It will not receive any further support beyond v47. We strongly discourage its use. Please navigate to the Meta XR Audio SDK documentation for your specific engine:
- Meta XR Audio SDK for Unity Native
- Meta XR Audio SDK for FMOD and Unity
- Meta XR Audio SDK for Wwise and Unity
- Meta XR Audio SDK for Unreal Native
- Meta XR Audio SDK for FMOD and Unreal
- Meta XR Audio SDK for Wwise and Unreal
This documentation is no longer being updated and is subject for removal.
The Oculus Audio Loudness Meter only runs on Microsoft Windows.
Installing
Download the Oculus Audio Loudness Meter package from the Audio Packages page.
After downloading the package, extract the contents of the .zip file to the desired location.
