Audio spatializers use physical characteristics of a scene, such as the distance and angle between an AudioListener and an AudioSource, to modify the properties of sound transmitted to the user. Spatialization can improve the perception that a sound originates from a specific location in a scene.
The Unity audio system supports spatialization through plug-ins built with the Unity Audio Spatializer SDK.
Unity doesn’t provide any built-in spatializer plug-ins itself, but several plug-in implementations are available in third-party 3D audio SDKs. These audio SDKs typically provide additional Unity components and tools for 3D audio. To learn about common audio spatializers for XR projects, refer to Audio spatializer reference.
After you have added the package containing an audio spatializer plug-in to your project, you can enable the plug-in in the project audio settings.
To enable a plug-in:
