Spatial Audio Formats
distribute 360-degree video to virtual reality platforms and players
More and more possibilities for an immersive audio experience can be seen – or better heard.
Since different platforms sometimes require different spatial audio file formats, I want to give a brief overview of the current situation in terms of virtual reality sound.
If you want to know more details, read my article about the pros and cons.
So feel free to contact me if you have any updates or questions.
- YouTube now supports iOS devices for spatial audio playback
- YouTube also enables stereoscopic VR180 Videos
- The Desktop Version of Oculus Video for Oculus Rift now supports the "Two Big Ears" Format.
- HTC Vive Cinema supports a great variety of surround sound formats!
- GoPro VR Player (former: Kolor 360° Video Player) now supports spatial audio!
- Mach1 Spatial Audio added to SamsungVR for GearVR and Android
- VideoLAN VLC Media Player (VLC 3.0 Vetinari) now supports higher order ambisonics
- Windows Mixed Reality Headsets (e.q. Samsung Odyssey) are supported by Vive Cinema via Viveport. Credits to GRID Lab at Ohio University. Vive Cinema is also supported by Oculus.
- Samsung Gallery for GearVR claims to have "3D spacial sound". You get a feel of head-tracked sound, but even if you load a stereo, it will create two sound objects in space which will rarely correspond with the visual.
- Oculus Video Player for GearVR both Two Big Ears and ambiX
- Oculus Go added. Oculus Video Player and Oculus Gallery allow watching videos made for YouTubeVR and FacebookVR offline as mp4 before uploading. SamsungVR Video works similarly to GearVR. Thanks to Angelo Farina for testing.
- YouTube now supports an optional Head-Locked Stereo track just like Facebook
