Normalizing has a place, but in general it's bad more often than good in
common practice. Every DSP operation can potentially add noise and
degrade audio quality, and add truncation distortion if not dithered.
Also, successive DSP processes really can degrade sound quality. On the
other hand, if you are doing a small gain change and dithering correctly,
and it's the last step of the process (besides dithering of course), that
is, not going to mastering, not having any other processing done, not had
a gain change done already, then it can be OK.
