This guide describes how to install and use the Oculus Native Spatializer plugin in Unity 5.2+ and in end-user applications.

The Oculus Native Spatializer Plugin (ONSP) is an add-on plugin for Unity that allows monophonic sound sources to be spatialized in 3D relative to the user's head location.

The Native Oculus Spatializer is built on Unity’s Native Audio Plugin, which removes redundant spatialization logic and provides a first-party HRTF.

Our ability to localize audio sources in three-dimensional space is a fundamental part of how we experience sound. Spatialization is the process of modifying sounds to make them localizable, so they seem to originate from distinct locations relative to the listener. It is a key part of creating a sense of presence in virtual reality games and applications.

For a detailed discussion of audio spatialization and virtual reality audio, we recommend reviewing our Introduction to Virtual Reality Audio guide before using the Oculus Native Spatializer. If you’re unfamiliar with Unity’s audio handling, be sure to review the Unity Audio guide.

Note: The Legacy Audio Spatializer for Unity 4 has been discontinued. The final version is available with Audio SDK v1.0.4 on the Downloads page; select the Audio category and version 1.0.4 to download.

General OSP Limitations

  1. CPU usage increases when early reflections are turned on, and increases proportionately as room dimensions become larger.
