TuneLab Pro measures and graphs the amplitudes of the first 12 partials,
but does not measure dwell time, which CyberTuner does.  However,
only TuneLab shows a spectrum display that is continuous, not
just a bar graph of the partials.  This allows you to see separate peaks
for each string of a mistuned unison.
