Last Updated on January 4, 2021.

Good mastering plugins can be hard to come by, and they can definitely be expensive!

This is why I created this list of the best free mastering plugins which should help you get your mixes to a new level while not spending anything!

let’s start things off with a bundle of free plugins that will already cover all your needs;

Noiz-Lab LE is a collection of five free mastering plugins developed by homestudiomastering.com.

Youlean Loudness Meter 2

Youlean Loudness Meter 2 is a free loudness metering plugin that features four metering modes; LUFS, LRA, DR and true peak.

It’s one of the most accurate loudness metering plugins out there, even when compared to other premium ones, and a vast number of producers use it during the mastering phase.

Even though you can get it for free, it does have a Pro version which comes with additional features.

This is an essential tool for any producer, especially if budget is an issue, since it will help you determine the proper amount of loudness without sacrificing quality or dynamics.

Because of it’s exceptionally visual interface, you can not only hear- but see what is going on, which can help beginners to better understand what is going on in the mix.

Not only this, but it includes loads of presets so you can make sure to sound great on all the streaming platforms like Spotify, YouTube, etc.

SPAN by Voxengo

SPAN is a free spectrum analyzer plugin that is absolutely essential to have for mastering if you want your mixes to end up sounding loud but not crushed.

It has a fairly simple Interface, which makes it easy to use, and it’s very accurate and useful, plus it’s compatible with almost any DAW available right now.

Not only is Span a spectrum analyzer plugin, but it can also do K-system metering.

It comes loaded with features such as being able to route multiple tracks into SPAN and then comparing their frequency content.

LoudMax by Thomas Mundt

LoudMax is a Loudness Maximizer Plugin that is designed to retain the original character of the music as much as possible, even at high compression levels.

It’s a very simple yet powerful tool that has two sliders, which are: Threshold and output.

LoudMax is a plugin that I’d recommend to beginners since its simplicity will better help you understand how to properly use a limiter.

But, even though it’s extremely simple, it’s still a great plugin!

Limiter №6 by Vladg Sound

Remember I said that LoudMax is a very simple plugin with just two controls? Well, Limiter №6 is far more complicated to use, with the advantage of being a lot more versatile as well.

It offers more control than LoudMax, meaning that it allows you to do more detailed tweaking, and it has five modules which include: RMS compressor, peak limiter, high-frequency limiter, clipper, true peak limiter.

And just as a note, even some premium plugins don’t come with such features included.

So, definitely give it a try!

TDR Nova EQ (Windows, Mac)

Nova is a parallel dynamic EQ that offers four bands which also include a fully-featured dynamic section each, and this means that the EQ can cover a huge variety of applications.

It may look intimidating and hard to use at first, but in reality, its interface and layout are quite intuitive and easy to navigate, which is why it’s easy to recommend even for beginners.

The interface provides an easy drag and drop display paired with a classic “knob” interface which allows for quick and smooth access to the various parameters that Nova EQ offers.

Additionally, it also comes with an additional high-pass and low-pass filter sections.

All in all, Nova EQ is very easy to recommend since it could easily be a premium plugin.

Voxengo Marvel GEQ

Having a good EQ is essential for any mixing and mastering engineer, especially one like the Marvel GEQ since it comes with a “undo/redo” function, which is something that not many plugins offer, especially free ones.

Marvel GEQ offers extensive internal channel routing capabilities, and supports mid/side channel processing.

Supporting mid/side channels is a fantastic feature since it allows you to treat the information in the center channel in a different way than the information on the sides, and this can end up yielding a much cleaner stereo spread.

The Marvel GEQ deserves a spot on this list not just for it’s great sound quality, but mainly because it can treat the mid and side channels differently, and because of the redo/undo function, which will prevent a lot of headaches!

Related: Looking for free compression plugins? Then here’s a list I wrote just about that topic.

TDR Kotelnikov (Windows, Mac)

Contrary to most compressor plugins in existence, this one doesn’t try to emulate any existing hardware compressors, quite the opposite in fact.

Named in honor of Vladimir Kotelnikov, who was a pioneer of digital sampling techniques, this plugin is purely digital and uses complex algorithms to provide the best control possible over the dynamics with minimum added color.

You have access to two different versions of the plugin; the free one and the “Gentlemen’s Edition”, which costs $44.

What sets Kotelnikov apart from most other compressors is its “Frequency Dependent Ratio”, which allows you to set a different compression ratio depending on the frequency (not available in the free version).

A similar feature is the “Low Freq Relax” that allows you to configure a high-pass filter for the side chain, which makes the compressor react less to those lower frequencies such as kick and bass, and this one can be found both on the free and premium versions of the plugin.

In other words, when using the “Low Freq Relax” feature, you are effectively lowering the threshold on the lower frequencies.

Another feature are the Ying and Yang controls, which add harmonics to the lower and higher frequencies respectively.

Lastly, when processing stereo channels, you also have the option to only process the Sum or Difference channels, otherwise known as the Middle or Side, and you can even use two instances of this plugin to compress the Mid and Side independently.

This plugin clearly does a hell of a lot of things, but it does them right, and for only $44, or even free, I honestly don’t find a reason not to recommend it.

Stereo Buss by Minimal System Group

This is a free compression plugin designed specifically for Master Bus compression.

Compression helps glue all the tracks together to create that sense of congruency in the mix, and this plugin does a great job at that!

Basically, if you’re looking to add some finishing touches to your mixes, then Stereo Buss might be the compression plugin you need!

Tip: Try introducing the Stereo Buss Compressor early in the mixing process, some people find this to be a better way of doing things.

You can download it here.

Stereo Tool v3 by Flux

StereoTool is a free plugin that offers precise control over the input gain and individual pan for left and right channels.

It also comes with an accurate visual feedback, reflecting the content with;

A vector scope, PPM meters for inputs/outputs, phase correlation meter permanently monitoring the signal and individual left and right polarity reversal.

Stereo Tool v3 is a fantastic plugin if you need to solve some problems with the balance of your stereo image, or if you’re having phase issues.

You can download it here.

A1Stereo Control by Alex Hilton

Often times you’d want to give your mixes a wider and expansive sound, and this is where A1Stereo Control comes in.

Not only is this plugin great at enhancing the stereo field, but it also features the “Safe Bass” algorithm which centers everything below a user-configurable value.

This gives your tracks the solidity and definition you want while preserving maximum transparency and sharpness.

Simply turn on “Safe Bass” and adjust the frequency if needed and that’s it.

You can download it here.

Wider by Polyverse Music

This is a simple free plugin that widens your stereo signal without causing any phasing issues because the widened signal will always remain in phase.

It’s extremely easy to use because you can only control one parameter; the width.

And that’s it!

It creates a much wider stereo feel and it doesn’t mess with the phase at all!

This is an excellent plugin that I absolutely recommend!

IVGI by Klanghelm

I love Klanghelm plugins; I use a couple of their compressors and they all work amazingly well!

So, it’s no surprise that this saturation and distortion plugin is also worth mentioning!

Adding a bit of saturation to your final mix can completely change the way it sounds, and this is where IVGI comes in;

Not only can IVGI add warmth, but it can also be used to completely distort tracks, as well as letting you alter the frequency dependency of the saturation with the RESPONSE control.

If your mix is lacking warmth, use IVGI to subtlety add some!

You can download it here.

Conclusion

I hope I was able to provide the information you needed here.

I believe that all of the plugins on this list are absolutely amazing considering that they are free!

Wider is fantastic, and I also love Youlean Loudness Meter and mvMeter 2.

Give them a try and see how you like them!

Have a great day!
