analysis of multimedia software:
MP3 uses audio compression technology to compress sound into files with a compression ratio of 1: 1 or even 1: 12, which can maintain good sound quality. Because the full name of this compression method is Mpeg GaudioLayer 3, people call it MP3 for short. Music stored in the form of MP3 is called MP3 music, and devices that can play MP3 sounds
are called MP3 players.
MP3 is the most popular music format on Inter, which originated from the EU147 digital transmission plan of a German company in 1987. It uses the technology of Mpeg GaudioLayer 3 to compress sound files into music files with a compression ratio of about 1∶12, which makes transmission and storage more convenient, and is more beneficial for Internet users to listen online or download to personal computers.
at the same time, the popularity of MP3 format music has also led to the emergence of MP3 dedicated playback devices, which have developed rapidly in recent years. At present, the popular MP3 devices in the market have gone far beyond the original "player" category in terms of function and performance, and gradually developed into multimedia handheld devices integrating audio playback (including music formats other than MP3), recording and rereading, text reading, mobile storage, FM radio and other functions. Some high-end MP3 devices even integrate audio editing, movie playing and other functions.
Advantages of MP3
There are many advantages of MP3, mainly including three points: First, because the file size is greatly reduced, more information can be stored in the same space; Second, because there are no mechanical components, all of them are electronic components, so there is no shock problem, which is more suitable for listening to music during exercise; Third, you can edit your favorite songs at will.
Disadvantages of MP3
There are advantages and disadvantages, and MP3 also has some disadvantages. MP3 audio compression technology is a kind of distortion compression, because the human ear can only hear the sound in a certain frequency band, and other sounds with higher or lower frequencies are useless to the human ear, so MP3 technology removes this part of the sound, thus greatly reducing the file size. Although it sounds like MP3 music still has the sound quality close to that of CD, it is a little worse than CD after all.
