Your Sound Card should have a Mic, Line in, and line out, sockets. Your recording controls (presuming, of course, you are operating Windows) can be accessed by (double) clicking on your wee 'speaker' in the tray,/ Options/Properties/Adjust volume for recording.

There is a current thread (MP3/Mudcat Future I think) where there is more info of recording from the ra format into WAV and MP3.

Have fun.
