Oculus Audio Loudness Meter Overview
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The Oculus Spatializer Plugin has been replaced by the Meta XR Audio SDK and is now in end-of-life stage.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This documentation is no longer being updated and is subject for removal.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 measures the overall loudness of your app’s audio mix.
Loudness goes beyond simple peak level measurements, using integral functions and gates to measure loudness over time in LUFS units according to ITU standards (BS.1770-2).
Target LUFS ranges
In the interest of providing a consistent audio volume experience across all Meta Quest VR experiences, we ask that you set a target of -18 LUFS for Rift apps and -16 LUFS for standalone apps. If the loudness profile of your app exceeds these thresholds, adjust your audio mix until your app no longer exceeds them.
This guide describes how to use the Meta Audio Loudness Meter to profile the overall loudness of your app.
Additional Topics
  • Setup
  • Measuring Loudness The Loudness Meter continuously monitors the selected audio interface to compile an overall loudness profile for your app.
