What is Dolby ?

Dolby Labrates, Inc., Named Dolby in everyday life, is an American company founded in 1965 by Ray Dolby. It specializes in reducing background noise and audio encoding and compression. Since its creation, its technologies have equipped both the tools of music and cinema professionals as well as those of the general public-the Dolby NR-B system teams from 1968 casserole recorders, for example.

What are its flagship products ?

Let’s start with Dolby Stereo – quickly renamed Dolby Surround. This has designated, since 1975, one of the features offered by Dolby and presented as a revolution in the experience of the cinema spectator. At the time, in addition to the noise reduction, the Dolby Stereo promised to reproduce the “enveloping” (surround) effect of sound from only two audio tracks. As it works with mono spotlights as stereo and that it is relatively simple to set up, the system is quickly adopted by cinemas.

As long as you have the sufficient number of speakers and positioned them correctly, it allows you to return the sound of a passing car or a jungle full of animal rustles behind the spectator. The feeling of being immersed in the film is accentuated.

Wait, what is this multi -channel audio story ?

Since the beginnings of sound recording, technologies have greatly evolved to provide an ever greater immersion of the auditor or the auditor in the sound he listens. In practice, we went from recording on a single track (its mono, one channel) to the possibility of recording it on several tracks.

Here is the nomenclature that differentiates the different types of recording ::

• 1.0: recording on a channel (monophonic, mono for intimate);
• 2.0: recording on two channels placed against the listener (stereo);
• 2.1: two front channels and a channel for the bass;
• 5.1: three front channels (right, center and left), a right back, a left back and a channel dedicated to the bass;
• 7.1: Three front channels, two side, a right back, a left back and a channel dedicated to the bass.

At the broadcast, in the cinema, for example, each track is broadcast by a speaker placed in a different location compared to the auditor or the auditor. This makes it possible to spatialize the sound, therefore to give a greater impression of reality.

What is Dolby Digital ?

Dolby Stereo was developed at the analog era. With the advent of digital technology, we had to change the sound management tools: Thus was born Dolby Digital, a name that includes a series of technologies dedicated to digital audio, in particular subject to sound compressions with losses.

The common point of the various Dolby Digital technologies (Dolby Digital 5.1, Dolby Digital Ex 6.1, Dolby Digital Live, etc.) is that they allow to encode a multiplicity of audio channels (up to six) to reproduce the horizontal spatialization of sound. If we draw an imaginary circle and place the listener in the center, the Dolby Digital 5.1 breaks into several channels. A channel dedicated to encoding the sound that will come from left, one that will come from the center, one for the right, one for the side surround and rear left and one for the side rear side surround. Not to mention the additional and optional channel dedicated to low frequencies.

What is the difference between Dolby Atmos and Dolby Digital ?

Last born in the company’s technologies, Dolby Atmos adds a new layer to the sound weaving that allows you to dive the spectator into the film or the series it watches: to the multiplication of points broadcast horizontally, the system Dolby Atmos allows you to add vertical variations in sound. Succinctly, if all the variations in the Dolby Surround then Dolby Digital made it possible to place the sound on a two -dimensional card, the Dolby Atmos allows it to be deployed in three dimensions, in a “bubble”. We then go from 5.1 to 5.1.2, the ” .2 »Designating 3D channels (we can go even further, depending on its configuration).

For your ears, it is as if you are in the middle of the concert or the action scene of your film or your video game. The level of realism is increased tenfold, with a spectacle allowing you, for example, to hear the cars which spin right and to the left, but also the possible helicopter that flies over you or the beast that spins you between your legs. Additional speakers also make listening more precise, with more nuances in the effects reproduced and finer acoustic benefits. Dolby offers demos on its site.

Of course, it is a little more complicated to be equipped properly at home than in a movie theater. Nevertheless, the Dolby Atmos processors of Home-Cinema amplifiers and bars of its adapt. Bose, LG, Samsung and Philips have also developed small additional speakers to add to its installation to reproduce the vertical effects.

Today, there are more and more devices compatible with Dolby Atmos, whether it is televisions, sound bars, video game consoles, TV boxes, helmets … Note however that it is necessary that each element of the installation is compatible so that everything works. Also note that the more you multiply the speakers, the more the rendering will gain in quality. Be careful, moreover, to marketing promises: if a television, even a smartphone, claims to be able to return Dolby Atmos, it will not do it as well as a real installation with a high -end sound bar (example: the Sonos Arc) or, better, an amplifier connected to speakers. What to remember: Dolby Atmos is more and more accessible.
