MPEG Audio Decoder
MPEG Audio Decoder (MAD) is a GPL library for decoding files that have been encoded with an MPEG audio codec. It was written by Robert Leslie and produced by Underbit Technologies. It was developed as a new implementation, on the ISO/IEC standards. 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 while madplay is notable for its ReplayGain support. Development ended decades ago, and vulnerabilities identified since then have gone unpatched.

MPEG Audio Decoder (MAD) is a GPL library for decoding files that have been encoded with an MPEG audio codec.[2] It was written by Robert Leslie and produced by Underbit Technologies. It was developed as a new implementation, on the ISO/IEC standards.[3]
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[3][4][5] while madplay is notable for its ReplayGain support.
Development ended decades ago, and vulnerabilities identified since then have gone unpatched.[6][7][8]

MAD is a high-quality MPEG audio decoder capable of 24-bit output. All computations are performed with fixed-point integer arithmetic, making it ideal for systems without a floating-point unit. The implementation is entirely new, based on the ISO/IEC standards.

Among the special features of MAD are 24-bit PCM resolution and 100% fixed-point (integer) computation.
