Thanks Jeurgen. If it does the function I described, then great. I
downloaded it and it's free, but on my Win7 machine it said it
couldn't detect an imput. I'll try to correct that or move it to
another computer. It's a single .exe file and doesn't spray your drive
and system folder with hundreds of folders and files nor modify the
registry, just like in the old days when people used to know how to
write software.

And to Loscha who may have replied to me instead of the list by
mistake. Yeah, I too have been using Cool Edit. I would run a sinewave
sweep through a piece of gear for about 30 seconds, then it would
display on the screen as a big rectangle in the waveform display
outlining the freq plot. I would then open the FFT window and I could
move the pointer on whatever peak or dip in the background wave
display and read off the freq on the FFT window. But if I wanted a
more accurate visual of the plot, I would have to run the .wav file
through an app I wrote that would warp it into a linear dB scale. That
was a pain. I later learned I could run a single tick sound (file with
a single sample set to max) and that would cause me to record the
impulse response of a piece of gear. Then by just opening the FFT
display I would get a finished plot the way it should look. Something
I just remembered after I started this thread, so that second way
might be just as easy as using another piece of software specifically
for the task.
