Being able to normalize audio to a given subjective loudness level is an important part of modern technique. This video shows how.

In this tutorial we will normalize an audio clip to a defined LUFS level.

The audio clip could be anything, but we will use a short poem, recorded at Abbey Road Studio 2. Firstly we will hear it and see it in the edit screen and mix screen of the digital audio workstation, which in this case is Pro Tools but the same principles apply in any DAW.

As you can see in the video just below the fader in the mix screen, the peak level is -2.5 dBFS, but this isn't a good measure of how loud the audio sounds subjectively.

For this, we need to measure the level of the signal in LUFS, meaning Loudness Units, relative to Full Scale.
