Here's a pretty standard shot of the program that shows the ControlStrip. There's a log frequency scale, and the amplitude and frequency scales are zoomed all the way out. There is a peak plot and an average plot showing.

This shot shows the "ControlBar", which is easier to use at the beginning, because all of the controls are right there in front of you. There is a linear frequency scale.

A black background is the standard, but a white background is very useful for printing.

Here's how you add a plot to the overlay menu. Only the type of plots showing are available to load. There are 4 slots, and you can save and load plots to and from disk.

Once a plot is loaded, this is what the menu looks like. You can show or hide that plot, clear it from the overlay slot, change the color that its written with, or load a different plot.

Here are the 4 pages from the options window. You click on the tabs at the top to select each page.
