Hi,

How do you compare measurements from the same MLP, same room, same furnitures before and after creating IR filters and applying filters with CamillaDSP? Does it takes a separate computer with REW?

I'm asking because I took a new set of measurements and made certain by monitoring with helvum and Camillagui that the measurement signals from REW were routed through the speaker filters. I compared that with my initial measurements I made 1 day earlier without any DSP treatment.

I expected to see what should have been corrected (A/B). Since I can hear the diffference, and it's hige, I imagine I would see it too. To my surprise, the curves were identical. Once smoothed to 1/6, they were still perfectly superimposed!

Am I missing something?
