This is the beginning of "Iron Man" Trailer, listen closely to the distortion in the Center channel when ffdshow normalize.
when AC3Filter's One-Pass Norm is used, it is distortion-free. (2.6db gain ultimately)

MPC has One-Pass Normalization implemented as well,
under the Audio settings tab, it has a "Regain Volume" check box, which is exactly what I suggest for ffdshow, in order to implement the requested feature ("Regain Volume" unchecked) as well as keeping existing functionality. ("Regain Volume" checked)
clsid, albain, I would love to hear your thoughts about this requested feature.
do you agree that ffdshow has a place for such a feature?
do you think you can spare some time to implement this future? (I would greatly appreciate it)
I must stress again that the current normalization implementation is of low value. (no offence)
Thanks,
