Musepack is an audio compression format with a strong
emphasis on high quality. It's not lossless, but it is
designed for transparency, so that you won't be able
to hear differences between the original wave file
and the much smaller MPC file.
It is based on the MPEG-1 Layer-2 / MP2 algorithms, but since 1997
it has rapidly developed and vastly improved and is now at an
advanced stage in which it contains heavily optimized and patentless code.
This is the latest StreamVersion8 encoder.
It's needed to encode Wave files to MPC.
