MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a popular digital audio encoding and lossy compression format, designed to greatly reduce the amount of data required to represent audio, yet still sound like a faithful reproduction of the original uncompressed audio to most listeners. It was invented by a team of European engineers who worked in the framework of the EUREKA 147 DAB digital radio research program, and it became an ISO/IEC standard in 1991.
Overview
MP3 is an audio-specific compression format. It provides a representation of pulse-code modulation-encoded audio in much less space than straightforward methods, by using psychoacoustic models to discard components less audible to human hearing, and recoding the remaining information in an efficient manner. Similar principles are used by JPEG, a lossy image compression format.
The MP3 format uses a hybrid transformation to transform a time domain signal into a frequency domain signal:
- 32-band polyphase quadrature filter
- 36 or 12 tap MDCT; size can be selected independent for sub-band 0...1 and 2...31
- Aliasing reduction postprocessing
