For those who are interested in binaural rendering of B-format and HOA with head tracking (VR, 3D Audio headphones, ...), we have started to made available our SDK in which we have included capability to do that (we are strong supporters of the HOA paradigm!). PS: please do not see that as advertising, but mere information sharing ...

I haven't found any doc on how to make a youtube 360 video with spatial audio, but that might be there too. I have plugged their audio widgets into my Unity demo in place of my own audio widgets and after a couple of tweaks it all seems to work. I don't see a way to play a B-format file directly. Also, it looks like this is targeted only at headphones. I have always thought that one of the beauties of using ambisonic processing is that one can switch from headphones to speakers. My audio sources can be direct binaural, ambisonic to binaural, or pure ambisonic just by flicking a couple of switches. Also, even when in direct binaural mode, I built my spatializer to fade from binaural to ambisonic as you get more distant since once you are awash in reverb the CPU cost of the direct binaural isn't worth it. You can still do binaural for the whole ambisonic bus and reverb returns. I haven't figured out how to get 5.1 out of Unity, but I think it's possible. Also, as someone mentioned back there, having non-rotated streams can be useful. Not only do I have a B-format clip player, but you can switch it to a second ambisonic bus that is not rotated for things like background music that shouldn't track with head movements. If I remember right, MPEG-H supports two ambisonic streams for just such reasons.
