the Moving Picture Experts Group (Motion Picture Experts Group) video
and audio on the development of a set of criteria, including MP3
compressed audio signal is to design a new audio compression format
standard.
MP3 is the adoption of international standards in the third layer MPEG audio compression, audio signal compression on a grid innovation - small stone type, the Chinese also known as "network music." The third layer of MPEG audio compression than the first layer and second layer coding to be complex, but the sound quality than the first and second floors, even in comparison with CD sound quality. CD, sample rate frequency 44.1MHz, 16Bits, the amount of data to 1.4Mbps, while the corresponding Sports MP3 Players of MP3 data only 32kbps ~ 320kbps, is the raw data in 1 / 4 to 1 / 40. That is the traditional one CD can now be stored 4 to 40 times the music, but in the human ear sounds, feel the sound effects are no different. Mp3 is a kind of compression and decompression of the calculation method used to deal with a high percentage of sound information. iPod MP3 Players generated sound files sound close to CD, the file size is only one-twelfth of CD. If a disc can store about 15-20 form the first classical CD format, MP3 music, if saved as MP3 format, can store several hundred songs, which is its charm. MP3 occurs first goal is to reduce the file size to facilitate data transmission in the network, and to maintain the quality of the original close of play. disney mp3 player of the compression ratio can reach 1 / 4 to 1 / 40, but the sounds in the human ear, but no distortion, because it will exceed the range of human hearing the sound removed from the digital audio without altering the most The main voice. In addition, Hello Kitty MP3 Players can upload, download any other form of computer files, MP3 player with removable storage capabilities. MP3 player is actually a function of specific small computer. Small body in the mini dv player, the MP3 player has a memory (memory card), MP3 player displays (LCD display), MP3 player, central processing unit [MCU (microcontroller) or MP3 player decoder DSP (digital signal processor), etc..
