LUFS, dBFS, R128, dBTP, ITU BS 1770, ATSC A/85, PLR & PSR…
There are now so many ways to measure your music these days, it’s not surprising that one of the most common questions I get asked these days is
What do all these acronyms mean ?
In particular, people want to know about the new “ITU-based” loudness meters, which use mysterious new “Loudness Units” – LU for short, or LUFS to be more technical. Especially as mainstream software like Cubase 7, Logic and Ozone Insight begin adding support for them.
You know they’re important, you know that meters using the new system are appearing in more and more places – but how do you know what they mean ?
Well the good news is, it’s not as complicated as it seems. There’s a pretty simple relationship between the new LUFS measurements and older loudness measurements we’re used to, like RMS or VU levels.
