Version: 1.0 mppenc and mppdec in the same RPM.

Musepack or MPC is an open source lossy audio codec. It was formerly known as MPEGplus, MPEG+ or MP+. 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. This program handles encoding and decoding of the MPC format, which is an audio compression format with a strong emphasis on high quality. 
File version: mppenc 1.16, mppdec 1.95e.
