... not yet there. The good: It's good you can bleed some of the left signal into the right ear (and vice versa) and add some reflections (keep it very low to sound realistic, so listening through your headphones sounds more like listening in a real room. The less good: head tracking through the webcam is not fluent and only works in good lightening, the bluetooth head tracker is better but only does x/y/z angles of the head, not the position in the room. The sound often seems to "flange" or combfilter (when head tracking). The models/algos are not yet advanced enough and do have not enough user defined parameters to be accurate. Hopefully they will improve these over time but for the moment it's not reliable enough to make tracking or mastering decisions... PLEASE SEE UPDATE BELOW!!!
I literally end up pulling off my headphones because I think my speakers are on. I use it with the device that attaches to the headphones to monitor head position, which works flawlessly. The camera tracking isn't quite as good, but still impressive.
