MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a patented digital audio
encoding format using a form of lossy data compression. It is a common audio format for
consumer audio storage, as well as a de facto standard of digital audio compression for the
transfer and playback of music on digital audio players.
MP3 is an audio-specific format that was designed by the Moving Picture Experts Group as part
of its MPEG-1 standard. The group was formed by several teams of engineers at Fraunhofer
IIS, AT&T-Bell Labs, Thomson-Brandt, CCETT, and others. It was approved as an ISO/IEC
standard in 1991.
The use in MP3 of a lossy compression algorithm is designed to greatly reduce the amount of
data required to represent the audio recording and still sound like a faithful reproduction of the
original uncompressed audio for most listeners. An MP3 file that is created using the setting of
128 kbit/s will result in a file that is about 11 times smaller[note 1] than the CD file created from
the original audio source. An MP3 file can also be constructed at higher or lower bit rates, with
higher or lower resulting quality.
The compression works by reducing accuracy of certain parts of sound that are deemed
beyond the auditory resolution ability of most people. This method is commonly referred to as
perceptual coding. It uses psychoacoustic models to discard or reduce precision of
components less audible to human hearing, and then records the remaining information in an
This technique is often presented as relatively conceptually similar to the principles used by
JPEG, an image compression format. The specific algorithms, however, are rather different:
JPEG uses a built-in vision model that is very widely tuned (as is necessary for images), while
MP3 uses a complex, precise masking model that is much more signal dependent.
