Dolby brought Atmos to home theaters two years later. The theaters installed new arrays of overhead speakers for the debut of Pixar’s animated feature film Brave, which earned critical acclaim for the way it made you feel like you were in a space as part of the movie. This immersive audio technology was implemented in select commercial cinemas in 2012. Dolby Atmosĭolby Labs was first out of the gate with Dolby Atmos. Here’s how each company is approaching object-based sound. This is a really big deal for home theater’s future. The decoder in your A/V receiver assembles this information from the source-such as Blu-ray player or home-theater PC-and calculates which combination of speakers should work together to reproduce that sound in your room. Įach sound object is accompanied by descriptive information-metadata-that describes aspects of that sound, such as where the sound object is located in a room, or in what direction the sound should move along the sound field and at what speed. When sound is treated as an object, it becomes a real game-changer. Unlike traditional audio mixing, which associates a sound with a particular speaker on a 2D plane, object-based audio technology treats each sound (the roar of an airplane, bullets flying through the air, raindrops hitting leaves, birds chirping, and so on) as an individual object. OnkyoĬonventional surround-sound systems, such as this 7.1-channel setup, operate on a single horizontal plane.īoth Dolby Atmos and DTS:X are object-based audio formats. Sure, you could mount speakers high on the wall or even in the ceiling, but your playback equipment had no way of taking those placements into consideration. Fidelity and resolution have increased over the years, but recording engineers have never had the tools to deliver a truly three-dimensional audio experience in which sounds come from above you as well as around you. The audio for movies and music has always been mastered for 2D presentations only.

As a result, movie soundtracks and music encoded in these formats sound more realistic, more natural, more true-to-life. The immersive audio formats of Dolby Atmos and DTS:X add a third dimension-height-to immerse you in sound. You were surrounded by sound, but it was limited to a single plane. The low-frequency effects from a subwoofer are non-directional.

Early home theater audio gear delivered sound in just two dimensions: Audio events could be played only in the front left, right, and front center, and in the rear left and right of a room.
