LUFS

LUFS Definition - What is LUFS?

What does LUFS stand for?

LU is an abbreviation for the term Loudness Unit. Loudness Units differ from decibels in that decibels measure the level of air pressure generated by the sound, whereas Loudness Units are an arbitrarily established unit for audio work which allows a person to control the resulting output volume of a piece of audio. In practical terms, one Loudness Unit is equal decibel of air pressure generated by the audio. LUFS is a term for Loudness Unit Full Scale, which allows the measurement of loudness of a piece of audio without a reference, whereas a decibel measurement requires the reference of standard air pressure, against which to measure the air pressure generated by the audio.
