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
so-called MPEG 2.5 format. 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) 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
