OK thanks to those who gave me info about audacity, which may be needed.
However, what I want is for realband to do it, rather than have to run up another app (as RHARV pointed out).

I was intending using the MP3 for karaoke, although my recent tests seem to suggest that a WAV file works too, which I wasn't aware of. I have no idea if WMA files work too, so I will try that option.

Thanks to all for the help, much appreciated.
