TV common sense daily new knowledge: color audio sound technology analysis

When most consumers buy flat-panel TVs, they tend to focus on the appearance, panel, digital interface, etc. In fact, the so-called "watching" TV is of course not only "seeing", but also with sound coordination; especially when watching When a movie is a blockbuster or a live concert, if the sound system of the TV is not good enough to affect the effect, even if the picture quality is clear and realistic, it will inevitably be greatly discounted, and it is difficult to realize the feeling of being truly “immersive”.

Therefore, when we buy TV, in addition to "high definition", we should pay more attention to and understanding of its audio system. An LCD TV with high quality bass effect is more for music lovers and movie enthusiasts. The irresistible temptation, clear and realistic picture and shocking eardrum sound will undoubtedly make you completely immersed in the dreamy world of audiovisual. Today, we have come to sort out some common audio technologies in the current TV market. Let’s take a look.
What is SRS technology?
The SRS (Sound Retrieval System) is the most representative 3D stereo technology developed by the SRS Institute. At the heart of the technology is the ability to get surround sound with 2 speakers. More specifically, sound waves have their specific volume amplitude, propagation speed, and positional parameters at various spatial points in the surrounding area. The human ear can analyze these data very sensitively, capturing the strength, direction of movement, and position of the sound. There is a lag and break of the sound (the phenomenon of chaotic reflection after the sound wave hits the outer ear). After the sound wave delay is properly processed in the ordinary speaker, the technology of the output is the SRS technology.
SRS recovers the spatial information masked by traditional recording and playback technology. After decomposing the stereo signal, it can separate and recover the spatial curve and environmental information of the original sound, and then superimpose them into the correct spatial relationship. on. These spatial curves are processed through a patented frequency response correction curve that brings the reproduced sound closer to the musician's original intended and live effects.
