Content mastered for home reproduction includes all the audio objects from the original film, placed in three-dimensional space, just as in the cinema. These include stationary sounds that are reproduced through all the speakers, such as a music background or ambient effects. You will experience a soundtrack as you would in a real-world environment.ĭolby Atmos supports up to 128 simultaneous audio objects. Audio objects originate and move anywhere in three-dimensional space, including anywhere overhead. With Dolby Atmos, filmmakers simply determine where the sound should be located within a scene, and the system intelligently makes the speaker-assignment decisions. For channel-based audio, filmmakers must determine which speakers should reproduce which sounds, an approach that could compromise the artistic intent. This approach allows the filmmakers to focus on the story. A child shouting, a helicopter lifting off, a blaring car horn-the filmmaker can decide exactly where the sound should originate and where it should move as the scene develops. Any sound can be mixed as a single audio element, an object, that's independently placed in three-dimensional space. How Dolby Atmos Works Its Magic Audio Objects Take Flightĭolby Atmos is based on the concept of audio objects. You'll feel like you're inside the action, in ways you've never before experienced. Through the use of audio objects, overhead sound, and all the richness, clarity, and power of Dolby sound, Dolby Atmos turns your room into an amazing place for entertainment. They can be precisely placed and moved anywhere in your room, including overhead, to flow above and around you in three-dimensional space.

In Dolby Atmos, any sound-the helicopter, a car screeching around a corner, a melodic bird call-can exist as an independent audio object, free of channel restrictions. It's the first cinematic audio format in which sounds exist as individual entities, called audio objects. You hear it only from the small number of predetermined locations defined by the speaker setup, not as you'd hear it in real life.ĭolby Atmos, by contrast, frees sound from channels. While that helicopter can move across channels, it can't go above you. If a scene requires, say, a helicopter taking off, that sound has to be assigned to specific channels and mixed together with other sounds. Traditional surround soundtracks must confine all sounds to the 5.1 or 7.1 channels of a typical home theater setup.
