It looks like Auro3D is behind the times and already outdated at least in terms of soundtrack delivery method since it's based off piggybacking on today's channel based structure. Object based surround seems a lot more expandable with more precision because you truly can have each speaker location become an individual channel rather than each wall or ceiling array getting the same blanket information as before. I don't see how they could recreate Gravity's soundtrack, as I heard it in Atmos, with Auro3D and have the same accuracy of sound placement.
Barco ought to stop talking about their partnership with DTS and actually get on board object based surround.
Also, if you're looking at the basic Atmos configuration for the home with the least amount of speakers, you'd have 7.1 plus at least two overhead speakers for a greater sense of space. Auro3D, at least in terms of their diagrams, seems to require a lot more speakers for what they're trying to accomplish.
I could see this as a better than basic object surround speaker configuration: your typical 7.1 layout with wide front side-wall surrounds to better position sounds from on-screen to surround speaker locations plus four overhead height surrounds to create your x/y/z 3D positional points. There are bass management controlled outputs for front subs and surround subs. If you have more room, and the rendering software and soundtrack is capable (hopefully, they are) you can then start multiplying these particular speaker locations so sounds can travel in a much more pin-point accurate manner, more closely matching a commercial object based theater.
Again, I don't see how the industry can deliver this to the home without some kind of modular system of base rendering unit with a certain amount of speaker outputs and then a data-linked add-on unit to expand your speaker configuration if you so choose, especially if they continue to manufacture receivers rather than moving more towards pre-amp/processors and outboard amps.
Listen up, studios! Just say "NO" to DNR and EE!!
