Between the OVRLipsync and Audio Visualization plugins, perhaps some unique experiences are possible by integrating these with Nvidia’s new VR Audio Works for UE4.
This is an old thread! I suggest anyone who views this to check out the new Audio sub-forum: https://forums.unrealengine.com/forumdisplay.php?90-Audio, where discussions about the new Unreal audio engine are underway.
Cheers
