Device Overview

Name/Version: Volume Compensator 3.5
Author: LAEX  
Description: This patch compensates volume after passing some plugins.

Consist of two devices Compensator send (CS) and Compensator recive (CR). CS measures RMS and CR adjusts output level to same RMS. Put some plugins between them, make tweaks and listen changes only, no loudness increase or decrease.

3.5 Fixed bug with volume strike when effects chain is heavily clipping. Small fixes.

3.3 Updated GUI for reflecting Live's colours

3.2 Added Auto and Manual setting on Receiver
Difference number between R in and S out
Matching numbers on R became green

3.1 Single file patch

3.0.1 fixed No sound when transport is inactive, fixed routing

3.0 Added LUFS metering, Routing incteased to 30 channels. Small bug fixes.

2.0 New clear GUI, now possible to bypass all processing whatever it contains (native, M4L, VST, AU), Matched RMS now becomes green on Receiver, small bugfixes.

1.1 Added 5 groups to use in one project

Added video how to use plugin as reference tool

Simple video

Such a great idea!!!!

@Crampe Thank You!

Hey Folks! Please confirm if it works on Windows 10. I have some complains, but no chance to test.

Hi there...really nice information it is very helpful to me thank u

Hi, nice but I think it's the same as except you can use as many as you wish in a given project

Now if a utility were at the end of that chain, I could use the difference between the the CS and the CR to adjust the gain and then take out the instances of the volume compensators, right?
So wouldn't it be possible to construct the CR such that it's intended purpose is to be inserted before a utility and to then takeover the gain dial of the utility from it's current position?

It might be nice to carry these tools into a studio session, or a live situation if they prove to be solid, and then not feel inclined to leave them in place. I say any chance to take a m4l device out of the equation in a performance critical situation is probably the right move....

Such an odd behavior I'm getting from the receiver. When I turn it on, it sounds EXACTLY as the pedal effect that I had on to the right of it, EVEN when the pedal device is turned OFF. In other words, it sounds like a volume jump (and not that it is maintaining the same RMS) when the CR is turned on, although the values on readout is that it is dynamically attenuating the signal AND even when the device between the CS and CR is turned off, it still sounds like the effect of the device to the right of the CR is turned on (when it isn't) when the CR is turned on...

@c2001 You right! that the same, but Im just cannot found it when decide to make my patch. and for sure if You need staging of many tracks simultaneously use it.


thx for the plugin. great idea!

I have found a minor issue if your M4L-devices are used on multiple tracks. The current behavior is that all tracks send to "rms" but The send/receive must be track specific! You have to evaluate the track number (and use it as a prefix in order to send on "rms-channels".

Then I have an amendment. It might be a good idea to have a "adjust" button. Once pressed the RMS is calculated, transferred and the adjustments are made. After switching it off the sender/receiver do not have to work anymore.

Well then... keep on going!

@broah Link replaced. Try download again.

Love it! Thanks a lot!! :D

Loudness compensator for Master channel on the way!

Hey, the compressed file cannot open, it's corrupted.
Only for me...? I'm on MacOs 10.14.16

Hi, Yes same here, I am on windows 10

yeah I can't open the file

Just checked by downloading from Gumroad. all fine. try to use another unrarer. I use Winrar

Reuploaded ZIP file. Please redownload all who have problems.

Hi, great idea for a utility. I tried it but as soon as the "receiver" is activated, it goes silent.The audio is still visible before on the Ableton FX meter but the receiver cuts everything. If I bypass the receiver (yellow button), the sound comes back but obviously the gain stage didn't happen. Is there a particular thing to do with the routing? Mine goes Sender > FX > Receiver with Route on 1.

Awesome device!!

What about other DAW's ? Something planned? I would buy it

Hello, Seems like a great tool. I just paid, downloaded the device, put it in Ableton, put it in a channel and can not get it to work. It seems something is buggy with the Receiver portion. Any ideas on how to make it work?

gpsound, i'm having the same problem here, when the compressor starts to work,it makes crackling noises as well.

Thanks for the cool device!

I'm seeing a significant delay when I enable bypass mode on the receiver. No issues in processed mode.

Looks like it might be coming from your use of plugsend~/plugreceive~ ?

I found a workaround - group the entire fx chain including the receiver into an fx rack. Then you can enable/disable the entire rack to compare to dry with no latency issues.

Gumroad purchase page says "This product is not currently for sale." when you try to buy it. is there another link? Just saw a video on Ableton and this is a tool I would very much need thank you.

Not sure about this link, but check out Volume Buddy 2 from Noir Labs. They're both great.

Not Available?

Download link is showing this product is not for sale currently. and I cant download it :(

Due to Fraud attack, Gumroad closed link.
Now it ok. Download please!

Many thanks for this great plugin. I downloaded version 3.1, but unfortunately it simply bypasses every effect I put between the send and receive device. Am I missing something or is this a bug?

yeah thank you !

Great, thanks a lot !

Really useful plugin. Is it possible to view the volume difference/delta? (Maybe in smaller font beneath the actual volume.)

I often use this during gain stage, making in/out volume of an effect the same, and seeing the delta directly would make this smoother.

Came to post what S5T has already - getting the pre-post level difference (or even peak AND rms deltas, if possible) would be a lovely addition.

This device reminds me a bit of Perception VST, which I've never actually used/dropped the money on. Considering that's $149 I find this device being free/open source very kind and generous. Thanks!

very good,
but i have crashes with the last version,live 10 is up to date.

John Tejada brought me here. Thanks for the dope device!

gr8 tool!! thanks

I can't pay via PayPal =(
processed ...?

Ok, is fine. Thank you very much for such a treasure!!!=)

Great tool!

One small comment, With the dark theme in Live 11 the some of the text / button label (like RMS, Processed, LUFS number entry etc) are hardly readable. example: lightblue button with light grey text RMS.


This is excellent.
I bought this and Perception AB and compared them.
The output was exactly the same between them.

A feature that could be added is a freeze button like Perception AB has whereby the last computed difference is stored.
Or the manual switch could have a button that stores the auto value.
This would solve the issue where when you stop playing a track and restart it, you don't have to wait for the auto computation to finish processing.
