Heya, I don't wanna belabour the point, but I decided to reamp some of my Axe III impulses loaded into Cab-Lab with MPT processing turned off and all the filters not doing anything, etc etc. So trying to get a WAV sweep of my impulses for my Egnater 4x12 cab.
Here are the level stats:

The input signal was a 48kHz 60second long frequency sweep generated in Voxengo Deconvolver. You can see the differing peak measurements, which are always a bit different with the input sweep versus a live guitar tone (it seems anyway!)
This is why I believe normalization is not a good idea. There's a lot of variation here that would be lost if I just normalized each IR to a standard arbitrary value.
