'''MP3''' is short for '''MPEG-1 Audio Layer 3''' and it is the preferred audio format at The Mixing Bowl due to its compatibility and high quality when used at high bitrates.
The MP3 algorithm development started in 1987, with a joint cooperation of [http://www.iis.fraunhofer.de/ Fraunhofer IIS-A] and the University of Erlangen. It is standardised as ISO-MPEG Audio Layer-3 (IS 11172-3 and IS 13818-3).
 
  
It soon became the de facto standard for lossy audio encoding, due to the high compression rates (1/11 of the original size, still retaining considerable quality), the high availability of decoders and the low CPU requirements for playback. (486 DX2-100 is enough for real-time decoding)

It supports multichannel files (Although there's no implementation yet), sampling rates from 16kHz to 24kHz (MPEG2 Layer 3) and 32kHz to 48kHz (MPEG1 Layer 3)

[[LAME]] is the recommeded MP3 encoder at The Mixing Bowl. Some benefits of using LAME:
