Hey phasespace,
Welcome to QQ generally, and thanks for joining this conversation specifically (and thoughtfully). If you spend some time here--and I hope you do--I think you'll find that this place isn't populated with the bands of trolls, hotheads, egomaniacs and know-nothings that can drive people away from other, similar sites. If people occasionally get exercised here, it's precisely out of the passion for the music you spoke of, but also out of a deep knowledge of what's entailed in surround mixing of all kinds. We do in fact express our appreciation for good work, and we support--and sometimes even incite--efforts to get good mixes out onto the market. That's not to say we haven't been hard on the occasional industry insider who has now and again dropped by for a cup of coffee, only to run away after being bombarded with a thousand questions and complaints. But I think that's because it's otherwise so hard to figure out how to actually get any good information from behind corporate walls, let alone identify and get through to the people who are making what we might feel are bad decisions or engaging in questionable practices. (That's what's so infuriating about "customer relations" in general these days, right? Not only is it impossible to figure out who's responsible for anything, it's even more impossible to reach them--and that's all by design. At best you get to talk with an underpaid flak-catcher halfway around the world who can only dutifully follow their script and promise vaguely, and unconvincingly, that they will send your feedback up the ladder. As you say: no point in taking out your ire on them!)
That said: most of us here are broadly, painfully aware of the economics around Atmos mixing, including the fact that artists and mixers mostly don't have much say in what the big guys ultimately decide to do. Like
@fredblue, I don't have a lot of sympathy for the argument that said big guys are on a budget: Sony, WEA, and UMG aren't hurting, and if they feel they can't afford to pay for a "proper" Atmos mix, then rather than plead poverty they shouldn't do one at all. Doing otherwise will just sully the Atmos "brand." At any rate, in this thread we're not concerned primarily with merely-mediocre mixes by current artists. What we're trying to figure out in this instance is why Warners seems to be encouraging--or at least countenancing--the wholesale "upmixing" of tracks by legacy artists from their back catalog.
If only these tracks had what you describe as a "basic Atmos mix, where elements of the music [are] placed in different, stationary areas of the spatial field [with] surround reverbs, delays and effects panned around you." Instead, what we're getting is a gloried version of "all-channel stereo." That's just insulting--to fans, to Dolby, and to the streaming services--even more so in cases where perfectly good 4.0 or 5.1 channel mixes already exist, and Warners could simply convert those to Apple's "Dolby Audio" format (as Sony has done with some of its historical quad and 5.1 mixes).
So...yeah. I think the excitement over piecing together the likely mixer of many of these tracks has to do with at last identifying an actual human, rather than a faceless unaccountable corporation, who was involved in this. For my part, I don't want to pile on this guy or pillory him. Assuming he's not bound by an NDA (which he probably is), I just want to get some good information so that, hopefully, we can constructively intervene, correct the situation, and praise everybody concerned for Doing the Right Thing.
