mp4 Player,high-quality MP4,China MP4 Player

Whether MP4 Player be capable of producing high-quality sound, mainly by the sound decoder chip, Sound technologies and headset.
Recently, MP4 Player is beginning to show two major trends: First, prices are no longer high, the second is the sound quality as "high-end" sign. However, individual companies have declared their own sound technology "very good, very powerful", but consumers can only hear it with normal MP4 not the same, but do not know where they are actually good , but do not know what kind of sound suited to them. Recently, the Chinese Academy of Sciences Institute of Acoustics hosted an MP4 audio technology testing, for the first time was interpreted MP4 audio.

Most of them are cheating consumers
Experts said that at present the market for a description of sound quality MP4, most are deceiving consumers, such as certain international brands MP4 promotion of "high fidelity", "stereo", etc. It is not new technology. Many chinese mp4 manufacturers have mastered these technologies. And their prices are more favorable.

In fact, MP4 whether it can produce high-quality sound, mainly by the sound decoder chip, sound and headphone technology decisions. Among them, MP4 decoder chip as the soul determines the manner in which the sound was read out; high-quality headphones directly affect the MP4's sound quality, Audio decoder chip technology, mainly for a better way out of the sound reduction, modification and embellishment, it can make the voices of the same grade produced world of difference between the effect of decoding is the MP4's "magician" and therefore often assumed that the home theater , professional audio of the selling points. Currently, BBE, SRS, DNSe three kinds of audio technology in the MP4 most widely applied. And passed these technologies, consumers buy essentially be able to ensure the sound quality MP4. Then, what are their respective advantages and disadvantages?

Comparison of the three audio technology
According to the CAS Institute of Acoustics of the test results, BBE, and DNSe have equal shares in the audio test, SRS sound is not satisfactory. Which, BBE sound in the tenor, bass performance and gives a comprehensive experience on the way ahead; DNSe sound in the treble performance, details of the reduction capacity, spaciousness and a sense of the level of outstanding performance; SRS audio tests in the six projects are deductible finishing say that it is a pity.
In all of the audio technology, BBE identity of the most legendary. The audio technology was born in 1985, developed by the United States BBESound company, after 10 years of development is already quite mature. However, due to Yan Zhizhe very strict control over the technology, only a handful of companies authorized number of products is too small is a big drawback. The digital market, with SRS audio technology, MP4 is not uncommon, compared with those who do not take audio technology, MP4, this technology may well be an option.
