Ok you dang geek - what kind of a "visual frequency analyzer" do you have
access to?  A slow timebase, storage oscilloscope would be my first choice
for attempting this venture.  But I'm an electronics geek, too, even though
I'm a musician.  (:`/)

Ed:

Wavelab has something they call a 3D frequency analysis plot. For a 
wave file it plots time on the X axis, frequency on Y axiz and 
amplitude (the amount of stuff at a given frequency at a given point 
in time) on the Z axis. So that allows you to track over time. It's 
really not precise enough (you can't zoom in and out, for example). I 
think it was designed for comparing one mix to another. For regular 
geeky stuff like analyzing the An1X's waveforms (e.g. what edge 
setting gets me closest to a triangle waveform?) I use this free 
software:

http://www.sonicspot.com/wavetools/wavetools.html

It's stable and easy to use. And it's got the basic oscilloscope, 
frequency plot, level meter etc. I hear some of the new commercial 
plug-ins have all kinds of esoteric tools, but I can't bring myself 
to spend money on something like this. :)

Do you use any of these kinds of tools, Ed?

Hey Jerry,
    Your response reveals my age...!  I was thinking about all of this
expensive hardware you'd need for analysis - but it's all available with the
software and processing horsepower now.  Living in the past am I!

Well, its hardly just you and it's not age I think. It's just that so 
much is possible with software. The other day, at musicplayer.com, 
somebody presented a mix for people to respond to. People liked it. 
Nice saw wave leads, warm analog sound, etc. Turns out all the sounds 
from leads to drums were done on a free drum software called stomper!

Needless to say I downloaded stomper. :)
