If your dBFS peak levels go higher than -3dB, you might be in trouble. As a rule of thumb, RMS readings around -18dBFS and -14dBFS should be OK. If you don’t yet own a LUFS meter, remember to pay attention to your RMS readings. 15dBFS, your results will likely hit different LUFS levels every time and might end up sounding different. The dBFS scale only measures the electrical level of the sound. ![]() When mixing to LUFS values, your mixes will sound more consistent. This is to ensure healthy sounding audio and to avoid those annoying dynamic bumps between commercials and programme audio.Ī lengthy, more technical (but fun!) explanation of these things can be found here: Especially in broadcast media (TV, radio, etc.) there are standards that require the audio to have a strictly defined integrated loudness level, most commonly -23 LUFS. an iPad with headphones on the bus), and what the intended end medium is (e.g. your home TV set or a movie theatre). What this means varies depending on how noisy the environment is (imagine in-flight entertainment), what device you are using (e.g. You will still need to use your dBFS meters to make sure your signals aren’t clipping. It’s also good to keep in mind that different meters serve different purposes. The integrated loudness can be understood as the “overall” level of your audio. RMS tells you the the average power of the signal, but LUFS integrated loudness is more accurate in terms of our perception of loudness. LUFS meters will also tell you the integrated loudness of your audio, which is similar to RMS (root mean square) but more truthful in terms of our hearing. It was developed to enable normalization of audio levels, and matches how our ears actually perceive sound. The new standard for measuring audio loudness is LUFS (loudness units relative to full scale). ![]() To judge actual loudness, our ears respond to average levels, not peak levels. These meters display audio in dBFS (decibels relative to full scale) and only tell you whether your audio signal is clipping or not. Unfortunately your basic DAW meters aren’t giving you the whole truth about your audio. Here’s a fun video explaining what the loudness war does to audio in practice:Īudio produced for a specific medium should always sound pleasant, dynamic and more or less “equal” in terms of perceived loudness. But in order to make your audio sound pleasant and meet industry requirements, you need to know a thing or two about setting your audio levels right, and how to approach loudness when creating audio. Even if you’ve been producing audio for a few years you might be thinking: “ huuuuuh…?”.īy now you’ve probably heard about the loudness war, and we all know what it sounds like when audio “peaks”, “clips” or hits the “red zone”. A customer might tell you: “ we need a track with an integrated loudness of -23 LUFS, a dynamic range of ≤ 15 LU and a true peak of max -1 dBTP”. What the heck is dBFS, true peak, RMS, integrated loudness and LUFS? Why do I need to know these strange appellations?Īs a professional sound designer you will eventually stumble across technical terms referring to audio levels and loudness. ![]()
