What is Audio Normalization?

Audio Normalization is the process of adjusting the overall level of an audio signal to reach a target loudness or peak level. It is known for ensuring consistent volume across recordings.

The process typically involves analyzing an audio file and increasing or decreasing its gain so that it meets a specified level, such as a peak value (peak normalization) or an average loudness target (loudness normalization, often measured in LUFS).

Audio Normalization emphasizes consistency and balance, making different tracks or sections play back at similar perceived loudness.

It does not change the dynamic range of the audio unless combined with other processing like compression; instead, it uniformly adjusts the signal level.

Today, Audio Normalization is widely used in music production, broadcasting, and streaming platforms, valued for its role in delivering uniform and listener-friendly playback levels.
