Oculus Go Development
On 6/23/20 Oculus announced plans to sunset Oculus Go. Information about dates and alternatives can be found in the Oculus Go introduction.
Oculus Quest Development
All Oculus Quest developers MUST PASS the concept review prior to gaining publishing access to the Quest Store and additional resources. Submit a concept document for review as early in your Quest application development cycle as possible. For additional information and context, please see Submitting Your App to the Oculus Quest Store.
Working with Audio in Unreal
Audio is crucial for creating a persuasive VR experience. Because of the key role that audio cues play in our sense of being present in an actual, physical space, any effort that development teams devote to getting it should be worth the effort, as it will contribute to the user’s sense of immersion.
Oculus provides free, easy-to-use spatializer plugins for engines and middleware including Unity, Unreal and native development. Our spatialization features support both Rift and Android development.
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 presence in virtual reality games and applications.
Audio Features
Oculus provides the following audio tools:
- Sound Spatialization Plugins - The Oculus spatialization tools and integrations transform monophonic sound sources to make them sound as though they originate from a specific desired direction. For details of our spatialization features, considerations and limitations see Spatializer Features.
- Synchronization of Avatar Lip Movements Synchronize avatar lips to speech and laughter sounds with Oculus Lipsync.
- Audio Profiling - Use the Oculus audio profiling tool to track audio issues.
- Loudness Meter - Measure the loudness of your audio mix with the Oculus Loudness Meter.
Download and Use Oculus Audio Tools
See the following documents for Oculus integrations with popular development tools.
Unreal Engine
Oculus provides an spatializer plugin and a Lipsync package for Unreal Engine.
| Tool/ Download | Documentation |
|---|---|
| Oculus Spatializer for Unreal - Plugin integrated with Unreal Engine | Oculus Spatializer for Unreal Engine 4 |
| Oculus Lipsync for Unreal | Oculus Lipsync for Unreal Engine |
UE4 offers built-in HRTF-spatialization only spatialization for Rift with and limited support for Oculus Go and Gear VR. For an example implementation, see AmbientSound Spatialize in the Unreal Audio Content Example.
Note that when Unreal PC (Rift) applications are launched, if the OculusVR plugin is enabled and the Oculus VR Runtime Service is installed, then the application will automatically override the default Windows graphics and audio devices and target the Rift. The Oculus VR Runtime Service is installed with the Oculus app.

Sound design and mixing is an art form, and VR is a new medium in which it is expressed. Whether you’re an aspiring sound designer or a veteran, VR provides many new challenges and inverts some of the common beliefs we’ve come to rely upon when creating music and sound cues for games and traditional media.

Read the Introduction to VR Audio white paper for key ideas and how to address them in VR, or see any of the additional topics:
| Topic | Description |
|---|---|
| Localization and the Human Auditory System | Describes how humans localize sound. |
| 3D Audio Spatialization | Describes spatialization and head-related transfer functions. |
| Listening Devices | Describes different listening devices and their advantages and disadvantages. |
| Environmental Modeling | Describes environmental modeling including reverberation and reflections. |
| Sound Design for Spatialization | Now that we’ve established how humans place sounds in the world and, more importantly, how we can fool people into thinking that a sound is coming from a particular point in space, we need to examine how we must change our approach to sound design to support spatialization. |
| Mixing Scenes for Virtual Reality | As with sound design, mixing a scene for VR is an art as well as a science, and the following recommendations may include caveats. |
