If you’ve been wondering, “how many LUFS should my master be”, then this article is for you. We will also take a look at the meaning of LUFS and a free LUFS meter you can use in your DAW.
LUFS Meaning
LUFS, which is an acronym for Loudness Units Full Scale, is the industry standard measurement of loudness. Previously, you may have seen RMS (root mean square) used to measure loudness. However, LUFS quickly superseded RMS because it accounts for how humans perceive loudness. The science behind it is quite nifty and worth a read if you are interested in understanding how it is calculated. There are many different pieces that make up LUFS. These include K-weighting, which imitates the sensitivity of the human ear to different frequencies, and also the Fletcher Munson curve.
