It is always nice to hear from something that does this for a living to get their perspective. In your setup(s) do you follow the Atmos Studio guidlines. Reading through them, they seem to have different/more specific guidlines. Hopefully this is related enough to this thread in regards to atmos placement…Atmos isn't a mess. Dolby has been consistent about their overhead speaker placement since Atmos was released to the public. They have been as consistent about their speaker setup as Auro has been about theirs.
That overhead spec conforms with how an Atmos studio with a 7.1.4 monitoring system is to be set up. This ensures some sort of conformity between the production and reproduction of the content.
