The first is Loudness Normalization (more accurately, LUFS, Loudness Units relative to Full Scale), and the second is Peak Normalization. What Does Normalize Do?īut what does it mean to normalize audio? Precisely what does Normalize do? In fact, there exist two kinds of normalization. Sometimes you can edit an MP3’s volume using automation, clip gain, or a plug-in. There are situations where it’s best to abstain from using it simply because there are better ways to get the same result.
Of course, the Normalize effect should be used wisely. In fact, this used to be the problem about three decades ago, due to the processing algorithms. Some of them claim that normalization can degrade/change dramatically the way the audio sounds. There’s a myth about audio normalization that beginners bring up when they come across this topic.

The Audio Normalization effect has been around since the beginning of digital audio, but opinions in the music society are still contradictory.
