This was done by some of the Field Testers during development.  And of
course, it is important to really watch the input levels or you'll display
all sorts of artifacts that aren't really there.  But you already knew that.

My version of Spectrogram is the older freeware one, so it doesn't make
wonderful plots. But, you can do a screen capture under Windows, and then
paste that into a diocument.
