Dolby Audio exactly?
In fact, compared with TV, you may see this English more in the cinema, and this English will appear in almost all Hollywood blockbusters.
official introduction, Dolby Audio (DolbyAudio) technology is a series of powerful technologies used to provide rich, clear and exciting sound effects to theaters, homes and on the way. This technology can further enhance the infectiousness of entertainment by providing a vibrant listening experience for content used for broadcasting, downloading, streaming, playing in theaters or enjoying on CDs.
With Dolby Audio technology, it can achieve sound effects that enhance their listening experience from multiple levels for movies, TV shows, music and games. Dolby Audio technology provides surround sound sound effects with up to 7.1 channels, including virtual surround sound from any source and transmitted through headphones.
Dolby Audio technology works
Dolby Audio technology can integrate content produced in Dolby format (for example, Dolby Digital Plus technology in broadcast programs or Dolby TrueHD technology in Blu-ray disc) with auxiliary playback technology in devices such as set-top boxes, mobile phones and tablets, and home audio systems. This way, no matter where and how you enjoy entertainment, you can achieve a consistent and high-quality listening experience.
If it is corresponding to TV, Dolby Atmos has another technology.
What is Dolby Atmos (Dolby Atmos)?
In real life, sound comes from all directions, but the surround sound theater system based on traditional channel settings can only propagate sound and sound effects on the horizontal plane, including front, left, right and back directions. The reason why Dolby Atmos can achieve an incredibly realistic experience is that every slight sound in the picture is restored according to the direction of sound sound in its scene - including the vertical direction of the space. You will wander in an extremely realistic three-dimensional sound space, with various accurately positioned ambient sounds surrounding you like real situations. A new, magical and exciting listening experience, sometimes thrilling and sometimes hilarious, yet always fascinating.
Dolby Atmos Working Principle
Compared with traditional audio channel home theaters, Dolby Atmos clearly has more outstanding flexibility and adaptability. When using the AV receiver with Dolby Atmos function to play Dolby Atmos format videos, the receiver will map Dolby Atmos sound elements to the corresponding speakers, and the layered tracks are unique innovative technology. The clearer and more precise positioning of the theater sound effects truly reflect the creator's original intentions. Dolby Atmos format contains metadata records, which can automatically generate the best audio tracks for the theater. The theater system consisting of KEF speakers can enjoy the full Dolby Atmos sound effects.
Of course, not only can the sound be improved, Dolby has also made a difference in picture quality, that is: Dolby Vision!
Dolby Vision Diversion: HDR
Before we explain Dolby Vision in depth, it is worth talking about HDR first.
HDR or high dynamic range refers to images that display higher contrast than conventional images (standard dynamic range or SDR). The dynamic range of an image is the difference between its brightest and darkest areas. The higher this range, the more colors available on the screen and the higher the level of detail.
Then what is Dolby Vision?
In short, Dolby Vision can be regarded as an alternative HDR, but it is more advanced and has some obvious differences. The process starts with the initial video content and remakes the mastering, which ultimately allows people to experience the effect at home.
DolbyVision HDR comes with an additional intelligent metadata layer that contains frame-by-frame instructions to ensure image content is depicted as accurately as possible.
DolbyVision Compatible TVs use frame information from the source to improve brightness, contrast and color performance.Regular HDR will only send static images that apply to the entire TV show or movie you are watching, and is the most basic form of metadata.
DolbyVision can also be transferred over HDMI 1.4 devices, meaning that AVR with older formats can take full advantage of the technology. Dolby Visions compatible TVs can still see standard HDR content, but only display improvements in regular HDR metadata.
After reading the above content, I believe you will have a deeper understanding of Dolby.
