I believe pink noise is the way to go. Since it's contant energy, a properly adjusted eq will result in a flat curve. White noise will result in "wedge" shaped curve, ie climbing higher as frequency goes higher. I played around with the built-in pink noise generator, but I think I'm going to stick with the Autosound 2000 pink noise track as it appeared to be a bit flatter when played as a wav on my PC. My goal this weekend is to use their SpectraRTA software (the other versions appear to be overly complex and not as responsive) and the Autosound track ripped to a wav.

Cheers!
