I believed this guy until it got to the end. I know my way around audio enough to know that there is no reason to virtually recreate the ear (and head) shape for audio unless you are using headphones. Otherwise, it's redundant, so long as you still have ears and a head. This is 100% for personalized binaural audio recreation. You cannot map your ears to a dedicated stereo or surround sound receiver and speakers or TV, nor should you. Creative (the company) has a new chip that does this, and goes between the headphones and the source, and they also have an app that scans your ears. I wonder if they license this tech from them... I've read that the results are extremely convincing, though. This will be AMAZING for PSVR2, actually! It's just that this guy makes it sound like he knows all of the answers, and he left that very vital part out. Others have also mentioned that he was wrong about Xbox not having a dedicated audio processor, which I was pretty sure of, too. Now I have to question this guy's judgement on some of the other things, as well. He's not bad to listen to, though. I wonder if he'll admit he was wrong.
Honestly, I haven't watched a lot of YouTube vids on these consoles because so many seem to not have a complete grasp on both consoles yet. Seems like a bunch of half-truths everywhere.
