For mac, I can usually manipulate the sonogram the variables in
Amadeus to obtain very detailed sonograms.
http://www.hairersoft.com/Amadeus.html . Its real-time displays can
be insightful and its the best wave form editor for $30 I know of.
Another, free (and unusual) sinusoidal analysis and resynthesis tool
for studying what is going on is:  http://www.klingbeil.com/spear/.
Analyze a mono sound file first and then open it in the display
window. Rob D.
