Steve,
   This would be no problem at all. I would just take a white noise wave
file and then build a new gig file using it. Now that I know how, that
would take only 30 minutes or so, and running the recording only takes a
few seconds really, so it's no big deal at all for me.

   I can record a wave file using the white noise generator in Pro
Tools. I do not know if it qualifies as 'a very good white noise
source.' If you provided a wave file that you are happy with, then we
wouldn't have this uncertainly.

   Are you sure this noise you're seeing is *not* caused by me messing
up somehow in the way I constructed the gig file? If you provided a
well-known (to you anyway) noise source file would you be more likely to
see me making a mistake? If so, then I think it makes the most sense for
you to supply it.

Please remember, I have done very few gig files, and none of them for
'scientific' purposes! ;-)

   Sure. Get that much, make sure it's right, and then move on to the
other settings? Do you want all the filter types initially, or should we
just do the low pass and see if it is working?

   Can you put a wave file you are interested in on your web site
somewhere and point me at it? I'll download it and do it soon.

   BTW - Should i do this next set of recordings in mono?
