In Audio Industry, Dolby Atmos is set to be the next big thing in surround sound technology that has been generating a 3D aural experience in theatres since June 2012. Initially, surround sound are designed for only theatres but now the technology has ventured its way by bringing inside our homes, laptops, and smartphones. As of now, there are several devices which start supporting the Dolby Atmos Sound technology.
Dolby Atmos films are The Croods, Turbo, Planes, Inside Out, The Peanuts Movie, How to Train Your Dragon 2, The Good Dinosaur, Kung Fu Panda 3, Finding Dory, The Emoji Movie, Monster Trucks, The Secret Life of Pets, Trolls, Captain Underpants: The First Epic Movie, Cars 3, Despicable Me 3, and Coco, among other Atmos releases.
What is Dolby Atmos?
Dolby Atmos is the audio technology which concentrates on delivering it dynamically to our ears. It is a 3D system for audio. While watching the movie or video which supports Dolby Atmos on a compatible hardware, the sound will spread around in 3-dimensional space. A viewer will experience like they are in the middle of the action. Now, let us compare Standard sound technology and surround sound technology,
The sound will be delivered to you in channels while watching a video in a normal mode and a video supporting stereo; the sound will be pushed using two channels, one for each of your ears. When we turn to surround sound technology, it will push the sound and deliver the audio by using multiple channels.
Depending on your setup, the number of channels can be range from 5 to 9. This makes surround sound technology to deliver the audio dynamically to our ears.
In real life, the sound which you hear is not delivered in a linear motion. You will be capturing sounds from all around you. Dolby Atmos gives you that natural audio experience in every video and movies. It does not deliver the sound in linear channels rather than it pushes the sound by using multiple channels and spread around in a precisely placed 3-dimensional space.
How Does Dolby Atmos Work?
Speakers that requires Dolby Atmos can be fitted above and behind the audience instead of fixing it around and in front of an audience. Even some surround sound systems utilize the similar speaker systems by fixing it around. However, You will experience the difference between both the method. However, in Dolby Atmos, the sound is pushed towards a certain point in the 3D space and not pushed to a particular speaker.
By using 3D trajectory, the sound engineer will pinpoint the sound, volume, diffusion and even the size of the audio coming out of the speaker on a moving object.
Dolby Atmos Technology in Theatres
Initially, theatres are the first place to utilize the Dolby Atmos sound technology. To experience the real Dolby Atmos sound system, a theatre is the best place because it has big empty spaces which can contain the required number of speakers and there will be no interference from outside. To feel the precise Dolby Atmos, a set of 64 speakers is needed, and the only large budget movie could afford it due to high cost.
The base idea used in technology is by joining the sounds to a 3D plane which matches to the actual objects and persons in the movie. Then, the sound technology in Dolby software will merge those sounds to their corresponding set of speakers. Depending upon the object’s movement in the movie, the sound will move between speakers. You have to watch a movie which supports Dolby Atmos audio inside a compatible theatre to get the hang of it. It will be similar to watching 4K content in 3D.
Dolby Atmos at Home
To experience the Dolby Atmos sound system in a home, you need only 7 set of speakers, and for an optimal experience, Dolby itself suggests using a maximum of 14 speakers. But if your cost could afford, you can fit the full 34 speakers package to get the possible audio experience in the home.
Also, If you want a cheaper alternative, you can install Dolby enabled sound bars. Along with normal speakers, these sound bars pack upward with exciting speakers. These sound bars are required along with a set of 2-4 normal speakers to get a basic Dolby Atmos experience. Basic Dolby Atmos setup will be far better when compared to normal surround sound setup at home.
Dolby Atmos in Smartphones and Laptops
When comparing with Theatre and Home, Smartphones have become the head of content consumption. Because there are more people to consume content with their smartphones. So the smartphone manufacturers are ready to include 2K and 4K screens in their phones. But one key missing feature has always been audio quality. The speakers in the smartphones are an average audiophile and not powerful enough to deliver sounds.
Dolby Atmos processor is used in smartphones by inserting it inside; this processor renders the audio in virtual 3-dimensional space in both speakers and headphones. The effect is more dynamic when you are using headphones than on speakers. It also gives the best experience of Atmos-enabled content like games, and songs. Similarly, the same operation is taking place in Laptops too.
