Compress MP3

MP3 is short for MPEG Layer3. It is one of the streaming formats for storing and transmitting audio in digital form, developed by Fraunhofer IIS and THOMSON, and later approved as part of the MPEG1 and MPEG2 compressed video and audio standards. MP3 format is a streaming format. This means that data transmission occurs as a stream of independent separate data blocks - frames. For this, the original signal during encoding is divided into sections of equal duration, called frames and encoded separately. When decoding, the signal is formed from a sequence of decoded frames. MP3 is the most popular format for storing and transmitting information in digital form, using signal compression.

Compared to many other audio compression formats, MP3 provides the best sound quality and is now perhaps the second most popular after Audio CD. The MP3 format uses data compression algorithms that can reduce the amount of data required to play music. Compression algorithms in MP3 work with data loss. The principle of compression is to reduce the accuracy of some parts of the sound stream, which is almost indistinguishable to the hearing of most people. This method is called perceptual coding. At the same time, at the first stage, a sound diagram is built in the form of a sequence of short periods of time, then information is removed from it, which is not distinguishable by the human ear, and the remaining information is stored in a compact form.
