Yep, I agree with JohnM. When correct, the soundcard cal will look something like a flat line until you zoom in, and then they will frequenty roll off at the low end. There won't be all that raggedy-ness.

Oh, one other thing, limit your vertical axes from 45 to 104 dB. It makes viewing easier since we use that range for most people -- more "apples to apples."

Good luck!
