You're right, of course. I suppose all it does is move the unused part
of the dynamic range from above the peak level to below the quietest level.
Normalisation loses nothing, but better utilises the available bit depth.
This is a bit misleading. The signal was recorded using whatever range was
present at the time of recording. Normalisation cannot "improve" anything,
but it does mean that the peak level is at or very close to 0 dBFS, which
for many purposes (though definitely not all) is preferable. You would rarely want to normalize to 0dBFS before
using an audio recording
in a mix, for example (except that sometimes you would :)
Exceptions are good. 'Normalize' doesn't sound like something one would
want to do to music, but it's certainly useful to make compilations from
different sources easier to listen to.
