Over the years, the screens of our mobiles and their speakers have gained so much quality that they can now be compared without fear to those of our televisions. And we are not only talking about the screen hardware itself, but also about all the software and algorithms that exist to get the most out of them, such as Dolby Atmos and Dolby Vision .
With a model of consumption of visual and sound content completely different from the one we had five years ago, our mobiles have dramatically improved the two basic aspects to enjoy them, such as image and sound, that is where they come into play these two technologies for image and sound optimization.
Why do our mobiles need these technologies?
This is the first thing we must ask ourselves when we talk about the Dolby systems, which have garnered so much fame over the years in theaters around the world. The existence of these technologies makes great sense, because they allow us to fully squeeze the possibilities of our mobile screens, as well as the audio section. Although a mobile has first-rate hardware in both directions, if they do not have software and a specific chip compatible with Dolby, they will not be able to give everything they are capable of.
Therefore, that a mobile is compatible with these systems gives us an extra quality of image and sound . And that may not matter to you if you use your mobile to chat or surf on social networks. But if what you like is to see a lot of visual content and listen to quality audio, you will have to go to mobile phones that are compatible with this technology, which is even superior to other more common mobile phones such as HDR. Therefore our mobiles need these technologies as long as the consumer demands the best image and sound quality for the content they enjoy.
How do you improve the mobile with Dolby Vision?
The vast majority of mobile phones hit the market with imaging technologies like HDR10 +, at its best. Although this technology is the most widespread, it is not the best, because if we compare some data we can understand that with Dolby Vision we will be able to enjoy an even better image . The first thing we must know is that a mobile must have a specific chip in order to take advantage of this technology. The big difference with HDR is that while in it the image information is linear, with Dolby Vision it is modified based on what is appearing on the screen, to always show image quality.
Something that has changed with the arrival of HDR10 +, which does put aside that linear evolution and offers us an image that adapts in real time to the scene. In addition, Dolby Vision can provide much more brightness, up to 4,000 cd / m2 , four times more than HDR, although logically it may not be as much on a mobile screen, due to obvious limitations, but the proportion in the end will be the same , these values are mostly for televisions. The color depth is 12 bits compared to 10 in HDR, and there are also up to 4096 RGB tones compared to 1024 in HDR 10.
Of the three display technologies, HDR, HDR10 +, and Dolby Vision, the latter is undoubtedly the best of the three . But it is also the one that is currently present in fewer mobiles, which in general have opted for HDR so far. In this way If you find a mobile with a Dolby Vision screen and your thing is to see content on its screen, do not doubt that you will have the best image quality. An image that we will notice more contrasted, more colorful, and without losing detail with respect to a mobile that does not have this Dolby technology.
And with Dolby Atmos?
The concept is similar to that of Dolby Vision, only in this case instead of improving the image of the phone, it improves its capabilities to reproduce quality sound. But we are not only talking about more quality, but about an ability to wrap ourselves that we do not find in the usual sound systems.
The main difference is that whoever creates sound content, especially if we are talking about a movie or series with a high dynamic audio load, can locate certain sounds in a specific area at a spatial level . This sound technology can therefore place any specific sound in an immersive audio environment, in order to make the experience more realistic and those sounds come from a 360-degree atmosphere.
And that is what it offers if we are watching content on our mobile phone, a surround sound that brings greater richness to them. It is possible since this system can offer up to 128 sound tracks and up to 118 sound objects that can be recreated at different points in that surround audio. Therefore with Dolby Atmos we go from accessing a flat sound, at most with a stereo effect, to one with many more tones, and sounds that can appear in specific places. Logically, as in the case of Dolby Vision, the content we listen to must be compatible with this technology.
In this way with Dolby Atmos on the mobile we will be able to enjoy, for example, the sound of a mosquito, a ball, an airplane, a car, or someone talking as if we were placing it around us, in a 360-degree atmosphere in a three-dimensional space . That is the great value of this technology, providing a spatialized sound, like the one we have always enjoyed in cinemas or in Home Cinema systems. Logically this is something that we will notice more with quality helmets than with the phone’s speakers, even if they are stereo.
Therefore, if what you are looking for is to get a mobile capable of reproducing image and sound with the best quality, you will have to have both systems, both Dolby Atmos and Dolby Vision. While the former technology is available even in affordable mid-range mobiles, the latter is not so easy to find on a mobile. Which also shows that it is an exclusive technology and within the reach of few.
