Dolby Atmos, the channelless positional sound technology

The common person is normally reticent in terms of believing sure audio and video applied sciences, and absolutely they don’t seem to be going flawed. Many promise to enhance what’s already sophisticated, and saving digital positioning and determination, audio and video haven’t improved a lot in recent times. Does this technology do it?

Dolby Atmos, a mature technology that’s little exploited


As we might nicely have guessed, Dolby Atmos is a encompass sound technology for cinemas and likewise for house programs that was created by Dolby laboratories again in April of the 12 months. 2012. And though there was time and it was launched as a revolutionary technology in that 12 months, its implementation has been actually gradual worldwide, particularly in film theaters, however in recent times it has taken off exponentially.

But what does it add to the applied sciences that have been already on the market and the way is it completely different? The goal was clear: to supply a fascinating sound, to print actions to stated sound, to convey the influence of what’s being seen on the display screen and to encourage feelings.


On paper the whole lot is nice, in fact, with the finest intentions little question, however what about actuality and the way do they obtain “magic”? Based on what they’ve referred to as “audio objects.” In a typical multi-speaker system, let 2.1, 5.1 or 7.1, the total sound is moved from speaker to speaker, however with Dolby Atmos every sound is an object, so it may be moved independently throughout the audio system creating a way more real looking really feel.

No limitations by way of audio system to make use of


Another benefit is that content material creators, whether or not they’re filmmakers or any studio, do not need to encode the audio for 7.1 or 5.1 for instance, however the extra audio system the richer the expertise and the extra detailed it is going to be. Dolby Atmos additionally provides the peak impact to the audio system, because it not solely works the horizontal axis, but in addition the vertical one, one thing completely new in the business.

The technology is due to this fact the identical each in the cinema and in our house, the distinction lies in the variety of audio system, strategic positioning and high quality of the identical, however as a technology in itself it’s provided each in a single place and in one other, not modifications.


But sure, the studio has to adapt the content material of the cinema movie to the movie at house utilizing a sequence of house creation instruments, since the encoding strategies should not the identical. The benefit is that there is no such thing as a loss after encoding, so the high quality and positioning will probably be similar and can adapt to the variety of audio system we now have.

Given this, the most evident query can also be the most pertinent, what do we have to get pleasure from this technology in our house? First of all, a system that may play Dolby Atmos, that’s, a participant Blu-ray (together with sport consoles and streaming media) with a film in that format, a TV or monitor with HDMI 1.four or increased.

Dolby Atmos

The most speaker configuration is as much as 34, in a 24.1.10 configuration, that’s, 24 audio system on the ground or at the peak of our ears and 10 on the ceiling, however let’s keep in mind that there is no such thing as a optimum, most, or minimal configuration. It all depends upon the room the place we’re. Yes it’s true that Dolby as such specifies 34 speaker positions, however they’re suggestions based mostly in your checks and measurements, they don’t seem to be topic to be adopted as such.
