One of the things that few people usually notice when buying a smartphone is in its sound system , in the quality of the speakers it incorporates, in the possibilities of its audio output and whether or not it has a signal processor digital (DSP) that improves or adds effects and equalizations.
In addition, although many times we are sold phones as powerful multimedia machines, unfortunately the audio part is neglected or at least not given all the attention it deserves. This is exactly what Dolby wants to solve with his new Atmos system , which now seems willing to land on phones of higher ranges. What will it offer us? Will Atmos be the same in the mobile as in the desktop computers? Will it be worth buying a certified phone with this technology?
What is Dolby Atmos?
Atmos is the new multi-channel audio format that Dolby released a few years ago for the big movie theaters and you can get in the mobile as the dolby atmos apk and that since 2014 has started to reach the high-end home theater equipment. It is an evolution of current surround sound systems that promises to improve the realism of sound by adding new speakers on the ceiling or front that pointing to the ceiling simulate sound coming from the top of the room.
It is also the first home theater system that is not based on channels, but on audio objects (although there are also basic channels). Any sound that is heard in a movie scene (explosions, screams, shots, etc.) is an audio object.
During the editing process it is decided which audio objects will be how they will move in the scene and the DSP of the A / V receiver selects which loudspeaker and with what volume it will be played, regardless of what our speaker configuration is.
Films with Dolby Atmos sound come in Blu-ray Disc format or through streaming video services, and the current Dolby TrueHD and Dolby Digital Plus sound tracks are used to get the extra information of the new format.
How Does Atmos Reach Smart Phones?
Alright, all we’ve seen so far is Dolby Atmos for home theater equipment. But what about mobile phones? Will it be the same? No, the Atmos certification for our phones will be different , not being oriented to the reproduction in a room but on the phone itself.
Dolby Atmos arrives at smartphones as a powerful digital processing system for audio signals that, using a combination of binaural reproduction and the aforementioned audio objects, aims to offer improved surround sound in telephones. That is, Atmos wants to improve the sense of spatiality and the definition of the physical origin of the effects that surround the user in all directions. For this it will offer the following technologies :
Surround Virtualizer: Create surround sound through the headphones or the phone’s speakers.
Dialogue Enhancer: Improves the listening of the voices by intelligently increasing the volume of the dialogs on the rest of the sounds.
Volume Leveler: Maintains constant volume level in all phone applications.
Intelligent Equalizer: Dynamically adjusts the frequency response to reach the one we like the most.
Dolby Digital Pass-Through: Allows you to pass directly without touching the sound track to an A / V receiver so that it is the one that decodes it.
