Normalize
Normalizing increases the level of the entire sound file so that the loudest part of the sound is at the maximum playback level before distortion; it then increases the rest of the sound proportionality.

Most sound editors have a function called normalize and the program automatically normalizes your sound files.

When you normalize a sound file, you first chose the level you'd like to raise your sound to—it could be the maximum level, which is 0db, or a percentage of the maximum level. Many audio experts believe it's a good idea to normalize a file to 96% of it's maximum level. Doing this compensates for other people's computers that may not respond to sound levels the same way your computer does. In theory, normalizing a file to 100% should allow the sound to be played back at the highest possible level without distortion. In reality, normalizing a file over 96% of the maximum level creates distortion on some people's computers.



A drawback to normalizing files is that by normalizing sound, you increase background noise. Professional sound masters equalize their sound files before normalizing them, to eliminate as much background noise as possible before normalizing.
