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 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 the loudness measurements we’re used to, like the TT Dynamic Range Meter’s DR value, or good old RMS average levels.
The video above demonstrates all of this, as clearly and simply as I could make it – as well as an important complication with RMS levels that everyone needs to know about.
You can download the “pink noise” test file I use in the video to try this for yourself here.
I hope you find the video helpful, and let me know if you have any questions !
