MP4 (MPEG-4 Part 14)

MP4 is a file extension abbreviated of MPEG-4 Part 14. It is a media container format, that is, it is not in itself a coding format, but contains inside itself files of other formats.

MP4 is used to combine video and audio files, images, as well as subtitles and metadata (information about the file and its contents, such as date of creation, album names, etc.). In addition to using on individual devices, the MP4 format support broadcasting over the Internet, and therefore has gained particular popularity among various online video players.

Often, users need to get an audio track from video packed in MP4 format, which makes it necessary to convert MP4 to MP3. Technically, this process is divided into two stages: extracting audio content from the container and transferring it into MP3 format.

MP3 (MPEG-1 Audio Layer III)

MP3 is the most popular music format. The abbreviation .mp3 comes from MPEG-1/2 / 2.5 Layer 3. The format was developed in 1991, but it was published and began to gain popularity only in 1999.

The MP3 format uses a lossy audio compression algorithm. When compressing, some sound signals are removed from the file, which is practically indistinguishable by the human ear, as well as those that can be played only on high-quality equipment. The result is a file several times smaller than the original, while the sound quality is not so much reduced.

This approach led to the widespread use of portable mp3 players at the dawn of technology because made it possible to store quite a significant number of songs in a small device. In addition, at a time when the Internet speed was still low, it made it possible to exchange music much faster, which also affected the entire music industry.
