None of the sonogram tools I've used have come very close. Maybe I'm
not using them to their full abilities or using the right tools.  It
not unusual for me to discern differences of 1/2 dB and 1/24th of an
octave while making adjustments by ear. The sonogram apps I routinely
use have a minimum amplitude range of 20dB.  Are there sonogram apps
that can distinguish fractions of a dB while only examining a 1/4 of
an octave? This would be a very useful tool if it could also display
these factors in real time. Rob D.
