MAD ~ MPEG Audio Decoder


MAD is a high-quality MPEG audio decoder. It currently supports MPEG-1 and the MPEG-2 extension to lower sampling frequencies, as well as the de facto MPEG 2.5 format. All three audio layers — Layer I, Layer II, and Layer III (i.e. MP3) — are fully implemented.

MAD does not yet support MPEG-2 multichannel audio (although it should be backward compatible with such streams) nor does it currently support AAC.

MAD has the following special features:

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