Thanks heaps Eric

$ mplayer -ao pcm test.mp3

produced an output file generically called <audiodump.wav> which then
opened in audacity.

Reading <man mplayer> is like reading the tax act. You know it's doing
you good... but.....  I never did figure out the right options from the
man page.

Based on your email I googled and found:

which was also a big help.
