Thanks for an interesting discussion. I have been working with surround for many years, in large venues with live orchestra and 20+ channels surround systems, but for me the Dolby Atmos was a real game changer. Until that point music playback was a sound source playing in a room, regardless if it’s mono, stereo or multichannel. The room had to be taken into consideration, and the acoustics captured in the recording would be colored by the room you’re sitting in. Having spend my last year on Dolby Atmos tuning I really see the potential in the format for music production. In a acoustically treated room with proper tuning software (sorry, not aware of any off the shelf products) the result is astonishing. The possibility to actually create an environment where the music lives, not constrained by the listening environment, was for me is a totally new experience. Now the room captured in the recording is the you’re sitting in.
I agree that there is a lot of inconsistency regarding source material, and not everyone will have access to a properly tuned room/sound system, but I definitely believe there is potential in spartial music.
