Atmos
JimH:
Thanks, Steve, for the very helpful post. I added it to the wiki here: https://wiki.jriver.com/index.php/Atmos

Slerch,
I give you credit for the first answer which discusses the DD layer in Atmos and added data at that level. Atmos has added something to enhance the 3 dimensional structure of the soundstage.

Slerch,
Where does the secret sauce, extra data, come from? Are there 20+ microphones in the recording studio? My guess is it’s manufactured by “electronic enhancement” like turning mono into stereo of old.
I appreciate your comment about JRiver and its relationship with Dolby Labs. Gotta play nice in the sandbox.
I suppose the best explanation I can give is that the data added by Dolby is proprietary. No conspiracy necessary.
Your explanation tells me what is going on here, it’s not in the lay press. And I thank you for your candor and for your expertise.

When bitstreaming Atmos, JRiver isn't doing anything special. The audio just gets passed through untouched to your AVR. Same with any bluray player, streaming device, etc.

Just one of many articles found... "The general concept behind Dolby Atmos is that sounds are encoded as “objects.” Instead of sending an audio track to a specific channel, sound designers can assign an audio track to a location in the theater or room, including overhead."

This is starting to feel like conversing with a brick wall.

Your "guess" is incorrect. If you had read the previous posts and the provided links, you wouldn't even have to guess anything.
Dolby does not "add" or "modify" anything. There is no "electronic enhancement". It is simply a method for mixing sound. At a basic level, each sound on the track is an object that the sound engineer positions on the sound stage. For instance, the sound engineer might take "helicopter_sfx.wav" and position it above the listener. This information is then relayed to the AVR, which plays it through the height channel.
