I'll take a crack at it.
This program looks for room modes that are close together, which is not desirable.
The most important columns are:
Mode Frequency & Group weighting -
Group weighting tells you if the mode is isolated from others (iso) which is desirable. It Also tells you by color how close adjacent modes are spaced. If it finds room modes closer than 5%, it starts to change color. 0% is red.
What it doesn't tell you explicitly is how strong the modes will be. Generally watch for the axial modes as they are the strongest.
Ideally you will be able to choose room dimensions that spread out all the modes. The room ratio in the default entry fields is a known good one, so everything is green.
Try entering 20' x 20' x 8' to see what happens. You get two coincident axial modes at 56.5 Hz. This will be a problem!
The keyboard shows you where the room modes fall on the musical scale.
The text field contains a wealth of info - I can cover that once you've had a chance to play around and absorb everything above.
