In some computer or mobile phone manuals we can see the use of Dolby sound. In fact, Dolby sound has also become a selling point of related products, many friends have asked Xiaobian, what is Dolby sound? What are the benefits of Dolby sound? For the topics that everyone cares about, today Xiaobian will share with you what is Dolby sound, and what are its characteristics. What is Dolby Sound? Dolby sound is a kind of technology that adds and subtracts the noise reduction and boosting audio method introduced by Dolby, which can improve the sound quality. It is generally used in higher-end occasions. Dolby sound name: Dolby Pro Logic Surround Sound (English name: DolbyProLogic) is a sound surround system that makes the played audio sound more stereoscopic. It combines four-channel stereo into two channels by recording with specific encoding means, that is, the original left channel (L), right channel (R), center channel (C), surround channel ( The four signals of S) are encoded into LT and RT composite two-channel signals, and the encoded two-channel composite signals LT and RT are restored to the encoded left, right, center, and surround by the decoder during playback. The four independent signals that are not in each other are amplified and input into the left, right, center and surround speakers, thus giving an immersive feeling and being widely used in home theaters. Maybe everyone is not very familiar with reading the above content. Simply say that Dolby Sound is an excellent audio processor software designed to provide better sound effects, but the addition of Dolby sound requires speaker support in addition to the special software. Above we introduced Dolby sound effects using left, right, center and surround speakers, so the true Dolby sound effect requires a perfect combination of four speakers. Often seen on a computer or on a mobile phone with support for Dolby sound is a computer or mobile phone system integrated Dolby sound support, but as for the mobile phone "Dolby", it is just a promotional gimmick, using the phone's speaker to reach Dolby effect, but the sound quality technology may be slightly better. What are the benefits of Dolby sound? The biggest benefit of Dolby sound is believed to be self-evident, mainly to improve the sound quality. Generally speaking, the Dolby sound effect on the mobile phone or on the computer can roughly indicate that the sound quality of these devices playing music or video is better, but simple. The computer and the mobile phone can not really feel the powerful sound effect, but also need to combine the speaker system to achieve a more perfect stereo sound effect, combined with excellent surround sound, so the sound played has an immersive three-dimensional effect. Just need four speakers, and friends who know home theater may understand better. The latest Microsoft said that it will integrate Dolby sound technology into the Windows 8 system. At that time, our computer only needs to install the Windows 8 operating system to enjoy the Dolby sound technology, but without the professional speaker system, we still can't fully experience the Dolby sound effect, but There is also a certain improvement in a sound quality, and interested friends may wish to understand.
