Normilizing is the wrongest thing to do, it should be the last resource for increasing volume.
As Nigel said, there is other procedures for that as compressing, limiting, maximizing.
Normilizing is the worst word a engineer can hear and its a nightmare.
Try to delete that word from vocabulary and the function from the software too.
