In response to the above, SAM only works below 200 hertz. This is only part of the story though. I and many others have noticed unexpected things when using SAM, such as improved stereo imigary, cleaner mids and highs and so on. Some kind of strange effect, where cleaning up the bass gives improvements elsewhere.
And as to precisely what those SAM graphs represent, I have no idea, they look nice though.
