Dolby Atmos is a 3D surround sound technology launched in 2012 that places audio devices and speakers overhead to produce sound that comes from all directions. It analyzes which sounds should come from which speakers placed around the cinema, including on the ceiling above the audience. Last year, many home cinema manufacturers announced products to bring Dolby Atmos to home theaters, with receivers and speakers from brands like Denon, Onkyo, and Yamaha. While commercial theaters use many more speakers, home versions can add 2-4 ceiling speakers to create the 3D effect with help from Dolby Atmos decoding receivers.
