It is equivalent to the guy who listens to the music turning the volume
dial on the amp. It does not affect the mix at all.

If you export too soft, s/he will have to turn up the amp.


One positive side effect of normalization is that you get the best
signal/noise ratio for the exported target (usually 16bit). If the
loudest peak is at 0dBFS the whole [16bit] range is available for
dynamic range.  If the digital peak is at -6dBFS you get one less bit
dynamic range (with integer encoding).
