Cinema Surround Sound: What Is the Dolby Atmos Standard?
Dolby Atmos is a surround sound technology that lets sound be positioned in three-dimensional space, including height, rather than only being played from speakers placed around the auditorium as in traditional 5.1/7.1 systems.
To take advantage of Atmos, a film’s mix needs to be done in a certified Atmos mixing stage from the start — which is why choosing a post-production sound partner with the right equipment and mixing experience directly affects the audience’s final experience in the theater.
