Normalization
Definition
The process of scaling the overall level of an audio file to reach a defined target. Peak normalization raises or lowers the file so its highest sample reaches a specified level (e.g., -0.1 dBFS). RMS normalization targets an average power level across the file. Neither form processes dynamics — the file is scaled uniformly, not compressed or limited.
In Simple Terms
Scaling your entire audio file's volume up or down to hit a specific level—like adjusting the overall brightness of a photo. It doesn't change the relationship between loud and quiet parts; it moves everything equally.
In Practice
A dialogue track is peak normalized to -3 dBFS before editing to ensure consistent levels across all recorded takes before the mix begins.
Common Confusion
Normalization is not the same as Loudness Normalization or mastering. It scales the file as a whole without affecting dynamics, frequency balance, or the relationship between loud and quiet moments.
