Erf. Yeah, what you said. :-)

I have been through reading a good amount of Martin's
site and looked at the designs but I have to depend on text
rather than formulas for any understanding.

I am also curious as to why the software by Augspurgher
that's available from _audioXpress_ is not explored or reviewed
in the forums. Hell, I have not even seen it reviewed by
_aX_ itself.

I will take a closer look at your work and come back with
q's in a bit. I used the spreadsheet a couple years back
but I even have to refamiliarize myself with the syntax.
