LUFS Meter
A plug-in to measure and adjust the loudness similar to the human perception of loudness. Compliant with EBU R 128, ATSC A/85 and more.
Provides a unique and fast way to create initial faders up mixes and to compare with reference tracks on equal loudness.
Your new mix assistant
Before crafting a mix, levelling all tracks provides a great
starting point.
Save time and let the LUFS Meter do this tedious work for you.
Compare your work with reference tracks
To achieve beautiful results it's crucial to compare your work with reference tracks. Over and over again, until you reach the sound you are looking for.
A proven strategy is to bounce/export your work to an audio file and put it into a new project. Together with some reference tracks, each one on a separate audio track. Use the solo feature of your workstation to listen to the individual tracks. Take notes about possible improvements in your own work. Go back to your original project and work on these issues.
There is one catch though. A slightly louder track sounds better to the human ear (Even without knowingly noticing that it is louder). That's why it is important that all the tracks in the comparison are equally loud. Guess what? The LUFS Meter takes care of this.
Deliver loudness calibrated content
Add the LUFS Meter to the end of your processing chain. Press 'reset'.
Play from start to finish. Choose your target loudness and press 'adjust to'. Done.
Testimonials
Klangfreund's LUFS Meter is a cheap-as-chips loudness meter [...] A real boon if you reference a lot of different tracks while mixing, or if you want a whole bunch of demonstration audio files to play with equal loudness.
Mike Senior, recording engineer and author of my favourite book
Honestly, I've looked far & wide for a simple but sophisticated meter & this just does everything I want/need! Thanks for making such a fantastic tool!
William Dyar, Hills Audio Mastering
Klangfreund's LUFS Meter offers a tremendous value for anyone who is looking for a powerful and flexible metering option to add to their workflow.
Rob Stewart, Just Mastering, LUFS Meter review
If you are into the fader up technique of mixing, which I am, then you simply HAVE to get this: Three clicks and all the faders are synced and referenced for you without you having to touch any faders or adjust individual channels. Very clever and invaluable.
Eddie Bazil, author and sound designer for Emu, Roland, Akai and NI
This plug-in is quite deep and has a lot of options and advanced settings, but the basic operation is very easy... Kind of like FCP X.
