'''MPEG Audio Decoder''' (MAD) is a [[GPL]] [[Library (computer science)|library]] for decoding files that have been encoded with an [[MPEG]] [[audio codec]].<ref name="linux-sound mpeg players encoders">{{cite web | url=http://www.linux-sound.org/mpeg.html | title=MPEG Players & Encoders | publisher=linux-sound.org | accessdate=November 3, 2011 | quote=MAD Robert Leslie's GPL'd MPEG audio decoder}}</ref> It was written by Robert Leslie and produced by Underbit Technologies.

It consists of libmad, a software library, and madplay, a command-line program for MP3 playback. libmad is notable for using only [[fixed-point arithmetic]]<ref name="freecode mad" /><ref name="mp3-tech mpeg source codes">{{cite web | url=http://www.mp3-tech.org/programmer/decoding.html | title=MPEG source codes | publisher=mp3-tech.org | accessdate=November 3, 2011 | quote=MAD is an mpeg-1 decoder using only integer computation.}}</ref><ref name="manpages.ubuntu.com madplay">{{cite web | url=http://manpages.ubuntu.com/manpages/oneiric/man1/madplay.1.html | title=madplay | publisher=Ubuntu Manpage Repository | accessdate=November 3, 2011 | quote=Among the special features of MAD are 24-bit PCM resolution and 100% fixed-point (integer) computation. |
