Loudness normalisation and permitted maximum level of audio signals

The EBU has studied the needs of audio signal levels in production, distribution and transmission of broadcast programmes. It is of the opinion that an audio-levelling paradigm based on loudness is needed. The EBU recommends the measurement of the average loudness of a programme (‘Programme Loudness’) for the normalisation of audio signals. The ‘Ma

What Are LUFS?
LUFS stands for Loudness Units relative to Full Scale. It’s a standardized measurement of audio loudness that factors human perception and electrical signal intensity together. LUFS are used to set targets for audio normalization in broadcast systems for cinema, TV, radio and music streaming. If that sounds complicated, it just means that LUFS are ...
Why Do We Use LUFS?
You may not realize it, but most of the audio you hear in your daily life is tightly produced to sound great in the environment where you experience it. Movies, TV, radio and streaming services all feature audio meticulously designed to work perfectly on each platform. But how did we get there? Someone had to decide on the audio standards for each ...
Loudness in Music Production
The biggest obstacle for consistent sound across mediums is loudness. It seems like an easy problem, but making everything the same volume for every different playback system out there is pretty tough. For starters, what even is loudness? In your DAW you might think of the dB levels on your track meters. That’s a good start, but it doesn’t tell the...
How to Use LUFS
Metering audio with LUFS is a little different from the other loudness measures you’re used to. First off, there are a few different ways to use it. Here are the most important ones.
Why Do LUFS Matter?
At some point in the history of audio engineering, the music industry decided that recordings should be loud. The idea was that listeners would subconsciously prefer the CD that sounded loudest on their CD player. The evidence to support the theory was thin, but it set off a boundary-pushing race called “the loudness war.” Eventually the trend wore...

What are LUFS and how do you use them?

LUFS are loudness units that present one of the most accurate ways of measuring loudness for audio played on streaming services, film, and TV. But what are LUFS exactly? And how can we use them to accurately measure loudness while mixing and mastering?

What is LUFS metering?

LUFS stands for Loudness Unit Full Scale, which references Loudness Units to full scale (i.e., the maximum level a system can handle). Steinberg Cubase, PreSonus Studio One Professional, Magix Samplitude, iZotope Insight, and other programs now include this type of metering.

What is the difference between LUFS and scale?

The scale refers to the amplitude of a signal compared with the maximum which a device can handle before clipping occurs. LUFS – Loudness units relative to Full Scale. This is a loudness standard designed to enable normalization of audio levels. Loudness Units (or LU) is an additional unit.

What is dBFS & LUFS?

dBFS – Decibels relative to Full Scale. This scale is used for amplitude levels in digital systems (e.g. your DAW). 0 dB FS is the maximum level. The scale refers to the amplitude of a signal compared with the maximum which a device can handle before clipping occurs. LUFS – Loudness units relative to Full Scale.

What is LUFS and how does it work?

Many loudness metering plugins still use RMS, and many DAWs still use it as a metering tool.
. But LUFS will allow you to get much more accurate data, and can help you understand why your mix sounds the way it does.
. Why is this? LUFS takes into account ‘loudness perception’, and this is based on what is known as the Fletcher-Munson Curve.

What is the difference between LUFS and LKFS?

The measurement for LUFS is ‘Loudness Units’, and the ‘full scale’ refers to the comparison to 0dB being the loudest point along that spectrum before clipping.
. In some circumstances, it is referred to LKFS, which just means that the LUFS measurement is K-weighted – but they are essentially the same measurement.

What are the LUFS loudness targets?

Here are the LUFS loudness targets for each platform.
. Bearing all this in mind, depending on the purpose of the music you’re making, you might still want to go above the recommended average of -14 LUFS.

What is the difference between short-term and integrated LUFS?

Short-term vs.
. Integrated LUFS Short-term LUFS looks at a shorter window of time and is great for identifying the loudness of a particular section.
. The window of time that different plugins use for the short-term varies.
. In comparison, Integrated LUFS continues taking new loudness information into account over time and updates the average value.
