Yes. 4.15 is shipping with the version we are using for Robo Recall, which is a PC-only title. The other platform backends are in the works as we speak. A few of the Epic platform guys are helping me out with that effort. My goal is to have all the backend platforms working by 4.16, which includes Android. And thus, when the Android backend is implemented, it’ll have all the features. That’s exactly the point of doing our own audio renderer! And yes, Android is a perfect example as to the platform problem UE4 was facing. Not only does it not support spatialized audio (due to the limitations of the native android audio API), it also doesn’t support pitch shifting! OR any effects, etc. Just bad. Especially for GearVR.
