LU Meter MK2 2.1.1 is available, this update is free for owners of the plugin and includes:

  • Fixed group name not updating correctly in some DAWs

Make sure your loudness is right

The HoRNet LU Meter MK2 is a digital loudness meter with auto gain staging and grouping functions, the redesigned and resizable GUI hides an intelligent tool that will improve your gain staging and mixing.

LU Meter MK2 is based on the concept of Loudness Units, a way of measuring audio that takes into consideration the human perception of sound so that the same level at different frequencies produces different reading on the meter.

HoRNet LU Meter MK2 implements the momentary, short term and integrated reading from the EBU R128 standard and applies the concept of “auto gain” to that measurement type, making sure that the signal never exceeds the chosen LU level. Auto gain and metering operations can be carried over using EBU standard (summing all channels in a single reading) or as separate channels in a non standard way.

Since this meter measures loudness, single peaks may exceed 0 dBFS when auto gain is applied, for this reason we added a safety “peak protection”. If the gain applied brings the peaks above the chosen safety level, it’s adjusted so that those peaks are at the chosen value at maximum.

While the default calibration of the meter is set to -18LUFS (Loudness Units Full Scale) the plugin allows you to change this reference so that you can aim for higher or lower levels depending on your needs.

Loudness metering can help you better judge the level of your master or your single tracks as it will be perceived by the ear and so mix quickly and better.

HoRNet LU Meter MK2 comes equipped with our “auto gain” algorithm, this function lets you adjust automatically the gain of the track so that it’s never louder than the chosen level.

Send parameter to group or to all

Many parameters of LU Meter MK2 can be copied across different instances of the plugin and this can be done within the same group (for example your drums) or every instance.

This option is available for: Gain, Reference, Max. peak, Target, Mode, EBU mode, Auto and Color. To change the default behaviour you can right click on the specific control and change its preferences. A green dot next to each control indicates when the control is currently “Send to group” enabled, an orange one, when is “Send to all” enabled.


We decided to not provide a demo for LUMeter MK2 because we don’t want to to cripple our product too much and limiting the capability of this plugin for a demo would mean to provide a bad testing experience.

For this reason we offer an instantaneous full refund within 15 days of your purchase if you buy LUMeter MK2 and you don’t like it

Thank you for creating this helpful & reasonable plugin! I also got mine after the VU Meter MK4.

Gotten this after got my VU, as i try to learn to understand more of how working base on LU scale.. this thing as simple to understand as it is.. a truly user friendly, yet a go to on lazy submission day, put it in 2bus after print, let it do the auto, submit to client for review 🙂 and im done for the day … love it.

Martin WWW says:

Oh i just realized i can set things at proper level as i want in little tricky way but it works. very nice plugin !

Charles Karpiuk says:

This plugin changed the way I make music. Something so simple yet so powerful should honestly probably cost more than this. I use it on nearly every channel I have in any of my tracks and sets. I don't always keep it on there, but I use it to set the gain and move. This makes gainstaging super fast and efficient and let's me get to doing what I love… making music!

So, that said, I am currently having serious stability issues, but hopefully support and I can figure out a solution.

Jerry Tobing says:

30/70 for me… sometimes it works like a charm, but more often than not, the algorithm for the autogain destroys all semblance of transience (either deletes the transience entirely, or makes it deafeningly transient). It doesn't provide much choices to combat that, so depending on what you're working with, it might not help at all.
Although it does save me a few minutes from time to time, it usually needs the original sound to already be consistent, which in turn makes it easier to gainstage in the first place.

But for how cheap it is, I feel it's worth to buy if you'd like applying it on everything, and then just giving up on it and just gainstage manually.

Rafael Belor says:

very nice plugin! can you add an option to disable the metering to save CPU? <3

Robert Ryda says:

I have had the MK1 version since 2016 and I must say it helps to set balances and save time when working with different program material that has different compression within it. Sometimes you could use the pink noise layer at the right level and to set the volumes of separate tracks accordingly, but sometimes we change the levels and have to re-do everything etc. Since we live in the 21 century its a must have to help a person really work on music and stick these things, nobody ever will say thanks for, to the AI. In MK2 we trust. Just bought this upgrade. Saverio, you are a powerful man! Word!

Errol Hunter says:

Fantastic piece of kit, number one, wouldn't be without it, hope the upgrade is seperate, would like to keep the origional
