Many people seem to be confused about different ways of measuring loudness and also the always changing trends and opinions on the topic.   To answer the question directly, we also explain the difference between RMS and LUFS: RMS:  “Root mean square”. The average level of your audio signal, measured over a longer period of time, and close to what your ears perceive as the loudness of your audio. LUFS:  “Loudness units relative to Full Scale”. This is a loudness standard designed to enable the matching of perceived audio levels. So that different signals (or songs) will sound equally loud, no matter what the dB meter says.   Loudness Units (or LU) is a unit that describes loudness by taking into account how our hearing perceives volume. Not just pure sound pressure or amplitude, like “dB” does.   And again, “FS” means “relative to full scale”. So, for example, -18 LUFS means “18 LU away from the maximum of 0”. The difference between -23 LUFS and -18 LUFS, for example is 5 LU. Then we're sharing how we do it in our own projects:How loud do we master and why?How do we measure it?How important is it to us? And one final word of caution:Be careful about different RMS settings on your meters! AES-17 on/off makes a 3dB difference. One RMS value doesn't necessary equal another RMS value. Be careful when comparing anything, basically. There's many different ways to measure loudness and volume and it's easy to get confused and compare different things without noticing.More details on that in the episode. Let's go! -Benedikt--For full show notes go to: https://theselfrecordingband.com/155Send us Fan MailIf you have any questions, feedback, topic ideas or want to suggest a guest, email us at: [email protected]
