In the quarter century since Dolby first introduced home-theater surround sound, the systems have grown steadily more sophisticated: first two audio channels, then five, then seven. But the sound has always been two-dimensional, surrounding listeners in a ring, not a dome. With Atmos, Dolby and its A/V partners (Pioneer, Marantz, and Onkyo, to name a few) have added a third dimension: height, which audio engineers can use to place individual sounds anywhere in a 3-D space. Imagine watching Godzilla while helicopter rotors beat overhead.
