As already noted above, mp3 - the most popular audio format. Designed for a long time it was the German company Fraunhofer IIS. The emergence of this format was literally a revolution in the music industry because of its small size, while maintaining excellent sound quality. Ironically, this format could never find widespread because its creators, almost ruined the project prohibitive material needs. There has been no Nike advertising campaign, the format could only be played back on the player of the developer, the design of this player has been miserable and uncomfortable, and for the purchase of codecs developers demanded exorbitant sums. Fortunately, there were free codecs for this format of the party, and, in addition, the European corporation THOMSON take an active support and spread this format, making it one of the audio compression standards.

Mp3 format designed specifically for the Internet to streaming music files. This format uses a fairly complex algorithm coding, including both mathematical methods of compression and psychoacoustic model based on the characteristics of human hearing. This model uses the effect of lowering the sensitivity of the human ear in the perception of weak sounds, just after the high-profile, and the fact that the sounds above and below the specified range are not audible to most people. Sound when encoding in mp3 is divided into separate portions - frames. All of them are mutually independent, and each frame is encoded separately from the other. When playing these frames are decoded, and creates the effect of a continuous sound. Such file structure allows for rewinding it, which makes it possible to run the sound of a musical composition file from any location, not just the first. And besides, frame structure allows the most convenient to use such files on the Internet. After loading the first few frames, the player immediately starts to play them at the same time downloading the subsequent frames. It ensures the continuity of the sound you are listening to music on the Internet.
