FreeMPC is a freeware, graphical and easy to use application for listening and converting MPC audio files. It can convert MPC to WAV and to MP3 (all bitrates). So if you have some MPC audio lying around you can easily convert it to MP3 and listen to it on your iPod or other MP3 player. Or you can just convert it to WAV and put it directly in a CD or MiniDisc.
