So what’s is Dolby Atmos fuss all about? – Say you have a screen door banging in the wind. In Dolby 5.1, if a mixer wanted to send that banging noise to the right surrounds, it went to every speaker in the array. In effect, it wouldn’t sound like a single door, but rather several doors banging in unison. In Atmos, however, if a mixer wants to position that banging sound in a particular part of the auditorium, he can treat it in a manner analogous to the way it would be heard in the real world. The sound is emitted from a single point of origin and is heard as a punctual effect rather than as aural ambience emanating from a broader area of the theatre.
