Technically, you can in fact change the normalisation while it's in .MP3, but that requires decoding it, scaling all the coefficients, then recoding. This doesn't involve conversion to .WAV at any point, so it's lossless. And no, I have never seen anything that does this :)

I wonder if patents allow for such a program, even. Anyone a qualified patent lawyer? :)
