Good idea Nick - it saves dotting around between the Atmos and Auro thread, and watching the tumbles weeds in the DTS-UHD thread.
Personally I love these new immersive audio formats, even though I've only heard Auro3D so far, I just love the fact that cinema is trying to push the boundries of what is possible, both with this and 4K on the video side of things.
Sadly though, as far as I can see, given the lack of studio adoption for the home market, 3D audio seems to be teetering on the edge of the precipice that 3D video has just fallen off.
The biggest problem is that mainstream consumers don't even know what it is. I was at the cinema this Sunday, a Showcase Cinema De Lux, and they advertised their new X-Plus cinemas which have wall to wall screens and Atmos systems. But the advert just said "Wall to wall screens and immersive 3D audio" - no mention of Atmos anywhere.
When I speak to my friends, some of who have multi-channel movie systems, none (and I mean none!) have even heard of Atmos or Auro3D. Given that those of us with multi-channel systems in the home is already a fairly small niche group, the Atmos/Auro 3D enthusiast group is going to be tiny.
It's no wonder then that we're not seeing many blu-ray releases for either format. I don't know what the answer is, but unless something can be done to make 3D audio mixes ubiquitous, it might never get of the ground.
Personally I still thing that DTS hold the key - if they can package the system correctly, making it cost and workflow beneficial to the studios, and making it completely speaker system agnostic in cinemas and the home, they might just manage it.
