Dolby Atmos is one of the most significant developments in surround sound technology over the past decade. Compared to traditional surround sound systems where you could have the left, right, center, side, and rear speakers all around you for two dimensions of surround — Dolby Atmos height speakers add overhead sound for a third dimension to your soundstage that is object-based. (118 objects to be exact!) Atmos gives movie directors, audio engineers, and now music artists (with Apple Music’s spatial audio) the ability to add a sense of “height” or “elevation” to their presentation of sound. Before, they just had a balance to play with to position sound between the channels, but now there is a complete three-dimensional field that can place sound in an exact spot.
