Libmad library (part of MAD project)

MAD is a high-quality MPEG audio decoder. It currently supports MPEG-1 as well as the MPEG-2 extension to Lower Sampling Frequencies. All three audio layers Layer I, Layer II, and Layer III a.k.a. MP3 are fully implemented.

MAD does not yet support MPEG-2 multichannel audio although it should be backward compatible with such streams or AAC, nor does it support the so-called MPEG 2.5 format.

MAD has the following special features

  • 24-bit PCM output
  • 100 fixed-point integer computation
  • completely new implementation based on the ISO/IEC standards
  • distributed under the terms of the GNU General Public License GPL

The software is distributed as a library libmad and command-line front-end madplay.
