Dolby Atmos creates an amazing mobile entertainment experience with breathtaking, moving audio—sound that flows all around you.
Dolby atmos is the name given to the proprietary surround sound technology by Dolby labs introduced in 2012.
Dolby atmos takes the user into a 3 dimensional sound space by individually addressing up to 64 unique speaker tracks. Dolby achieved this by adding height-speakers and ceiling speakers therby placing the user in centre of all the three axis.
The Dolby Atmos technology allows up to 128 audio tracks plus associated pan metadata to be distributed to theaters for optimal, dynamic rendering to loudspeakers based on the theater capabilities. Sounds that are not dynamically moving, such as ambient sounds and center dialogues, are still separately pre-mixed in a traditional multichannel format.
During playback, each theater’s Dolby Atmos system renders all dynamic sounds, from the pan metadata, in real-time to make it seem like each sound is coming from its designated spot, with respect to the speakers present in the target theater. By way of contrast, traditional multichannel technology essentially burns the audio tracks into a fixed number of channels during post-production. This has traditionally forced the re-recording mixer to make up-front assumptions about the playback environment that may not apply very well to a particular theater (to the extent its capabilities differ from the mixing stage where the mixer was working).
Dolby atmos for commercial cinema – The first generation cinema hardware, the “Dolby Atmos Cinema Processor” supports up to 128 discrete audio tracks and up to 64 unique speaker feeds.
The grey speakers give the existing surround speakers and the coloured speakers represent the additional Dolby atmos speakers.
Dolby atmos for home – In addition to playing back a standard 5.1 or 7.1 mix using loudspeakers grouped into arrays, the Dolby Atmos system can also give each loudspeaker its own unique feed based on its exact location, thereby enabling many new front, surround, and even ceiling-mounted height channels for the precise panning of select sounds such as a helicopter or rain.
The configurations adapted for home include:
This is a spatial coding where the first digit is the no. of speakers in the X&Y axis.
Second digit is the no. of subwoofers.
Third digit is the no. of ceiling speakers/ height speakers.
Here’s how the Dolby atmos differentiates from the traditional surround.
Traditional – 5.1 surround.
Dolby atmos 7.1.4 surround.
By adding height/presence speakers the bullet actually goes through your body and the helicopter seems to fly right over your head.
Dolby atmos is by far the most breathtaking surround sound experience.
Dolby Atmos Benefits:
Dolby Atmos transforms mobile entertainment. Over built-in speakers or headphones, sound seems to come from all directions, including overhead, with astonishing clarity, richness, power, and depth.
It’s sound that excites your senses and inspires your emotions to deliver the full impact of entertainment.
When you put on your headphones, the sounds of people, places, things, and music seem to move all around and above you, so you feel like you’re inside the action.
