does the new Audio2Expression feature only work with audio from the microphone? I didn't find a way to feed in some other kind of audio stream. Not sure what the use case would be just using the mic, besides the existing demo? The more obvious use case would be to use it like OVRLipSync to sync any character / NPC lip movement with audio, but this does not seem possible right now?
*bump* I can not be the only one wanting to use this feature, so would like to know if this is just a showcase for now or if it's anyhow usable without direct mic input? I mean, what would be the use case of reacting to mic input anyway? Seeing yourself in a mirror as a speaking character? I cannot imagine any reasonable use case with current integration.
