I’m not getting Oculus spatialiser linking between FMOD and UE4 on Win10.
I have regular (non-Oculus) 3D sound working fine through Rift S.
Oculus Audio Spatializer Plugin for Wwise 25.0 A Wwise plugin to let developers add HRTF-based spatialization and room modeling to applications. For more information, see the Wwise documentation Audio SDK Developer Guide. View with your headphones onThe Oculus VR Audio Spatializer in Unity 3D demo app. Compare Oculus VR Audio Spatializer with Superpowered VR Audio Spatializ. This guide describes how to install and use the Oculus Spatializer VST plugin with the Oculus Rift. For an overview of all of the audio tools offered by Oculus, see Working with Audio in Unity. For general background information on audio spatialization, see our Introduction to Virtual Reality Audio. VST Spatializer topics.
As instructed here How to Use the Oculus Spatializer in FMOD Studio: Unreal | Oculus Developers I have my OculusSpatializerFMOD.dll (with text file ‘OculusSpatializerFMOD’) sat next to my fmod.dll files in UE4.26 > Engine > Plugins > FMODStudio > Binaries > Win64 but the OculusSpatializerFMOD doesn’t appear as per this image:
In UE4 the Oculus-Spatialized event sometimes appears as ‘3D - False’ in details, other times ‘True’ with 0 min and max, not sure where it’s getting 0 from.
Quick video demo’ing my test:
Other stuff I’ve tried:
guide from - Use the Oculus Spatializer for Unreal Engine | Oculus Developers
guide from - Set Up the Oculus Spatializer Plugin (OSP) for FMOD: Unity | Oculus Developers (no idea where mysterious 'Oculus Spatializer folder > AudioSDKPluginsFMODx64 folder is, i assume it’s same x64 folder from the download ZIP in ‘ovr_audio_spatializer_fmod’ folder)
in FMOD > Oculus plugin instead of spatializer on each event master track, mono in, stereo out
mixer master bus stereo out (tried both stereo and 5.1 in) and have Oculus Spatial Reverb
in UE4 > Platforms > Win > Audio > Spatialization and Reverb Plugin > Oculus Audio, and Plugins > Oculus Audio > enable Late Reverberation, Plugins > FMOD Studio > Output Format Stereo
any help much appreciated, thanks.
In this article you will find a guide to configure the Oculus Spatializer in FMOD Studio and then use it in Unityto build amazing Virtual Reality experiences for Oculus Quest!
Why should I go through all this pain?
If you are working on a VR project you know that audio is basically very very important.
The advantages of using an audio middleware to speed up your projects are many but something setting everything up can be messy.
I’ve been using the Oculus Spatializer for quite a while now and I believe it offers one of the best HRTF out there.
I’m assuming you already have installed the latest version of FMOD and Unity.
FMOD set up
First thing we need to get the spatializer plugin inside FMOD Studio.
Go ahead and download the package from the Oculus website.
As I’m writing this article, version 12.0.0 is the latest release.
Here’s how the folder presents itself.
The interesting stuff for this step are:
- Studio
- x64
As you have this opened, look for the installation folder of FMOD in you computer.
Mine is C:Program FilesFMOD SoundSystemFMOD Studio 2.00.0x
Inside here there’s a folder named “plugins“.
You need to copy all the files from “Studio” and “x64” into that folder. So far it wasn’t so bad, wasn’t it??
You are all set up now!
If you create a new FMOD project you’ll now find the option for Oculus Spatializer in the menu.
When working with Oculus Quest, remember to build your banks for Mobile as well!
Unity set up
Now the Unity part… what we need are two things:
- Oculus Spatializer package for Unity (we’ve downloaded it already)
Go ahead and import the integration for Unity, like any other package: double click on it while you have Unity opened in the background.
Now do the same think with the package you’ll find in the Spatializer folder.
Set the project path, so that Unity knows where FMOD project is located.
Go to the FMOD menu at the top and select “Edit Settings”
Now, in the inspector, select “project” and look for the FMOD Studio project file in your computer.
Tell FMOD you are using a plugin, add the string “OculusSpatializerFMOD” in the section Plugin.
Also make sure your speaker mode matches the one you’ve set in FMOD Studio!
If you are using Ambix files set FMOD to 5.1.
I know that Oculus documentation tells us to use Stereo, but if you do so, the routing of Ambisonics files isn’t quite right, so use surround and then only use the left and right channels on the master (as suggested by Gianni Ricciardi).
How many more steps????
Don’t worry we are almost there, just need to handle a little mess with the folders.
Last step, go in the assets folder and look for “Plugins/FMOD“.
Copy and paste the file OculusSpatializerFMOD.dll from Plugins/FMOD/x86_64 to Plugins/FMOD/win/x86_64
This is something that they should fix soon, basically they’ve changed FMOD integration folder structure, and the guys from Oculus haven’t caught up yet…
Now delete the folders Plugins/FMOD/x86_64 and Plugins/FMOD/x86 and you should be done!
If you don’t do so, you’ll have problems during build time, so make sure you have your folders fixed up.
This is how in the end folders should look like:
Building an app
It’s now time to create your application for quest.
Before you do, kill Unity’s audio engine, you don’t really need it, since we are using FMOD.
Go to Edit/Project Settings/Audio and flag “Disable Unity Audio”
Now you are ready to build without errors!!! Enjoy everything working smoothly!!
Oculus Spatializer Conflict
IMPORTANT
You can always be getting errors during build time!
At least now you should be confident that if you have any problems you should be looking somewhere else than FMOD integration!
When updates come out..
When either FMOD or Oculus update their software you might want to update as well, there are often new features and bug fixes.
Oculus Spatializer Unity
To update everything follow these steps:
Oculus Spatializer Vst
- Update plugin files for FMOD Studio, build your banks.
- Delete all FMOD files from unity, as well as dll (to delete dll files is better if you close unity and work directly in the project folder)
- Reimport new packages and configure Unity like described in the article
