%description
MAD (libmad) 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.

The library is available as 32-bit and 64-bit.

%description devel
MAD (libmad) 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.

This package contains the header file needed to develop programs that
will use libmad for mpeg audio decoding.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "xlc -q64" or "gcc -maix64".
