OVR Audio Lipsync streaming format for UE4

[michela]

Re. 1.30.0, any tips on how to stream audio produced as a Sound Wave object into an array of bytes? Unclear how to use Feed Audio Blueprint node as there doesn't appear to be any native Blueprint mechanism for reformatting realtime audio.

Use case: I'm generating text-to-speech audio as a Sound Wave object and would like to feed this to the OVR Lipsync

I'm also interesting in feed audio node. is there a way to feed audio with multi input devices and one  input to control one character's morph targets
