Sounds very cool.

In A/V reproduction accuracy, there IS no concept of "accounting for personal taste/preference". As art consumers we don't "pick" the level of bass, nor the tint/brightness of a scene's sky, any more than we pick the ending of a novel or Mona Lisa's type of smile. "High fidelity" means "high truthfulness", faithful to the original artist's intent: an unmodified, neutral, accurate copy of the original master, ideally being exact and with no discernable alterations, aka "transparency".

Yes, they have Atmos for PC and Xbox One. (surprisingly not PS4 yet. Some developers say that Sony just needs to do a firmware update to implement it)

Also, videogame soundtracks are object based by their very nature. The sounds have to exist in individual sound files that the game pulls out and mixes into the soundtrack in real-time. If the game includes sounds of footsteps, the game doesn't know WHEN you are going to move your character. But when you do, it needs to mix the footstep sound into the soundtrack. Then it has to calculate the 3d positioning of the sound, its origin and the orientation to the camera. Then it sends the sound to the proper channel(s) in a surround configuration.

What a lot of people don't understand about Atmos and DTSX, is that this is how they work in movies. They have a standard channel based bed, but any sounds embedded as "sound objects" are mixed into the soundtrack in real-time by your receivers processing. The metadata on the disc tells your receiver that "this sound has to start in this x,y,z coordinate and end at this x,y,z coordinate. But the disc doesn't know how many speakers you have or where they are. It doesn't care. Your receiver takes care of all that and decides where the sounds come from and mixes it dynamically. Brilliant stuff. Sound designers really need to start experimenting with it and taking advantage of its capabilities.

Stand tall and shake the heavens...
