EQ & clipping madness -Sound Forge - PC - MAGIX Community Forums Archive

I'm working with some audio in Sound Forge 5 and have been mainly focused on the paragraphic eq. All I'm doing is enabling the high shelf and cutting all frequencies above 500Hz or so. I notice that when I process my audio this way parts of it now clip. I don't understand why. I have my "Dry out" set to -Inf dB and my "wet out" at 0.0 dB. In other words, there's no gain applied. If all I'm doing is REMOVING the high frequency components and not boosting any frequencies one should reason that I'd actually be making my audio quieter. For the most part this is true except in some particularly bass heavy parts of my audio where the sound actually begins to clip. How can this be? Why would some frequencies actually wind up clipping if all I'm doing is essentially applying a low pass filter with no gain? Thanks for any help. I'm really wanting to know what's causing this. I've also noticed this behaviour when I use the paragraphic preset to cut frequencies below 20hz.
