Just out of curiosity: Is there some way for consumers to "open" a Atmos soundtrack and see what speakers are outputting sound? I remember seeing some tool that visualizes the speakers as the soundtrack is playing. Is it also possible to edit this and re-compile it back into a finished atmos soundtrack? I ask because I have this 2010s film that was "re-released" in atmos that has a missing sound effect in a specific scene and despite my attempts to reach out to the studio and director, I cannot seem to get ahold of them. My next thing would be to try and re-add the sound effect back into the atmos soundtrack. Is this possible?
