Beats and oscilloscopes

[Joan Gladwyn]

Have you tried it using the free software, Audacity from sourceforge? 
(http://audacity.sourceforge.net/)  You ditch the CRO and record the 
sound straight onto the computer then you can see the waveform.  I 
haven't tried it for beats but it works for every other sound 
experiment I've tried.
