What is MP3 file?

MP3 is short for MPEG-1 Audio Layer-3 and is probably the most popular audio data file format in the world. This compressed audio format was created in early 1990s by Moving Picture Experts Group (MPEG). MP3 file contains a header, metadata, and actual audio data in compressed binary format (most of the file content is audio data).

Header holds information about audio data, including encoding, bitrate, and sampling rate. Metadata include information about audio data and is usually stored in ID3 format, which is widely regarded as standard, and is recognized by most devices and audio players.

MP3 file audio quality

MP3 compression method offers significantly reduced file size (roughly 1/10 the size of original file) and decent sound quality. Sound quality is determined by used compression settings, such as bit rate (constant or variable) or sampling rate. Higher values provide better sound quality at the expense of increased file size. Typical settings are 128 kb/s for bit rate and 44,1 kHz for sampling rate, which generate file of size 1MB for each minute of recording.
