If you find something please let me know. I am very curious if there is one. Maybe Dolby don’t record anything in a studio and if they do does it use the same angles as a home theater setup? Studios are typically small areas. Maybe studios are only used to record music and since Dolby is a home theater provider they don’t use a studio? I have no idea I’m probably overthinking it all. I just know that the angles of Atmos and surround sound placement are very crucial and make a significant difference in your surround sound experience. I just want to do it right before I build the room.
