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 :)
