For Mac OS X ... I used iSpectrum, from Dog Park Software.  I used  
the free demo version.  It was a snap, taking all of ten minutes.

``iSpectrum is an easy to use audio spectrum analyzer that allows the  
user to view live audio in a standard frequency plot, a stereo  
oscilloscope view and a waterfall display. The user can adjust the  
display resolution, center frequency and save images to disk.''
