Best 8 Mastering Plugins for Pro Tools (Free & Paid) – Blog

For many, mastering can be a particularly nebulous step of audio production.

This final act of polishing and preparing your track for worldwide ears is crucial, but can be confusing or challenging to even excellent mixing engineers. You might be an absolute pro at producing music in the DAW of your choice, but without a quality master, your hard work might not be heard the way you intend.

For those new to the concept of mastering, keep that last idea in mind. While not the sole focus, part of mastering is ensuring your track is exported at an appropriate loudness to the standards of other music we hear, and that your vision can be realized across car speakers, club PA systems, and the worst headphones you can imagine.

Fortunately, mastering plugins are improving and innovating each day, whether you prefer to take full control or allow tech to provide input. In this guide, we’ll explore the best mastering plugins for Pro Tools, including powerful free options as well as industry-standard paid tools, and also include some practical mastering tips to help you build the perfect Pro Tools mastering chain.

Feel free to use the table of contents below to quickly navigate to a specific section.

What you’ll learn:

Let’s get started!


Top free mastering plugins to consider

First, don’t fall into the trap of thinking that you need to spend hundreds to get started with mastering in Pro Tools. While there are certainly advantages to the top paid plugins, it’s important to always follow this rule of thumb when considering new software: before you buy, thoroughly understand, experiment with, and practically test what you already have and readily have access to. If you’re a Pro Tools Artist or Pro subscriber, for example, there are two excellent stock plugins which we’ve already overviewed.

There are also several free mastering plugins from third-party developers that I highly recommend that are compatible with Pro Tools. The more you save here, the more you can spend on other tools, your marketing, or most importantly, your cost of living as an artist.

1. Brainworx bx_masterdesk Classic

Brainworx comes in as a top recommendation, as they offer multiple free mastering tools. Within their collection, the plugin to prioritize trying out is the bx_masterdesk Classic. By boiling down the complexity of mastering to the three key categories of volume, foundation, and tone, it enables professional mastering results for beginners while professionals may also use it to save time.

If you want more control within the same interface, an expanded option is available in bx_masterdesk.

2. Voxengo SPAN

Similar to Brainworx, Voxengo boasts numerous free plugins, with the option to move up their product line if you become a superfan or just need something more. Between the Elephant Limiter, the TEOTE Automatic Master, and the SPAN Spectrum Analyzer, you can’t go wrong. The latter, however, deserves emphasis for its visualization of your balance across an entire track, giving you a real-time look at the FFT (fast Fourier transform) crucial to shaping your listeners’ experience.

3. TDR Nova

TDR Nova is a parallel dynamic equalizer with a sleek interface that doesn’t sacrifice precision. Designed with the look of a classic parametric equalizer, this plugin offers elegant answers to your key mastering needs.

Notably, TDR Nova also still offers a number of their legacy products that are no longer receiving updates. If you do a bit of searching around, you might also find articles similar to this one recommending the Limiter №6 by vladg/sound. This is one of such products Tokyo Dawn Records still offers for free, and if your system supports it, I highly recommend also giving this limiter a try.

4. Youlean Loudness Meter 2

While a number of mastering plugins will include a loudness meter as one of their features, Youlean proves the importance of giving it your full attention with this free analyzer plugin. Providing another highly visual experience like SPAN, this plugin is specifically designed for preparing your audio for streaming, television, and other uses connected with video.


Best paid mastering plugins for Pro Tools

With paid plugins, whether they’re standalone tools or upgraded versions like those available with Brainworx and SPAN, you can step up into truly professional-grade mastering.

If you take what you’ve learned from the free plugins, your skills as a producer will only be further unleashed with the magnitude of control provided by the following tools. Fortunately, paid mastering plugins don’t need to break the bank, either. You can take advantage of programs like Splice’s Rent-To-Own to try out a plugin for free and only start making payments towards the full price once you know that it’s for you.

With that, here are some of the top choices trusted by mastering engineers worldwide.

1. FabFilter Pro-Q 3

FabFilter’s Pro-Q 3 is an industry mainstay for a reason—with an intuitive interface and dynamic EQ bands, this plugin provides you with surgical abilities to shape your tone and experiment with transparency and curiosity for moments of magic. Pair this with their Pro-L 2 limiter for even more fun.

2. Isotope Ozone 11

Some will be surprised that it took us this long to bring up iZotope, given there are also a number of free options useful in the mastering process offered by them. There’s intention here, as there’s really no beating the behemoth that’s Ozone, which is also available via Rent-to-Own.

While many of our suggestions have been for individual components of a full mastering chain, Ozone is a premier all-in-one suite. If it’s in budget for you, including just the monthly cost as you try it out, there may be no reason to look elsewhere.

3. Waves L2 Ultramaximizer, Vitamin, and more

If you don’t opt for an all-in-one product like Ozone, Waves can provide you with a wide array of individual solutions that can suit your mastering needs.

For starters, I would recommend any combination of the L2 Ultramaximizer, the Kramer Master Tape Saturator, and the Vitamin Sonic Enhancer, though the list could go on. If you’re finding specific gaps in your mastering chain, consider looking through Waves’ extensive collection.

4. Manley Massive Passive EQ

Where are the hardware heads? Universal Audio touts some of the best software products mirroring pieces of hardware—in this case one which would cost you over $6,000. For less than 3% of that, you can use Manley Massive Passive EQ to expertly shape your masters with the punch, air, and sizzle of tube-powered hardware. For those eager to be given the flexibility and responsibility that comes with dozens of controls for tonal shaping, look no further.


How to use mastering plugins for optimal sound

Without the ability to use your plugins effectively, it doesn’t matter how many licenses you have. To truly excel as a mastering engineer, whether you’re pursuing it as a career or learning the skills for self-production, you need to know how to get the most out of each and every plugin. As a guitarist obsesses over pedals and strings, you must obsess over knobs and visualizers.

Creating the perfect mastering chain in Pro Tools

A mastering chain is the sequence of plugins you use on your stereo bus to prepare your final mix. As each effect works with the source material it’s given, it does in fact matter which plugin you choose to use first, so be intentional and lean on your fundamentals of sound.

Mastering is a culmination of numerous, intentional steps, some of which you’ll already be familiar with from the mixing process—but it’s how we apply each alongside the other parts of the chain that’s unique.

Here’s a simple yet effective mastering chain to try out with the plugins above and any others you want to experiment with Pro Tools:

  1. EQ: For corrective and tonal shaping. Here, you gently attenuate problematic frequencies like muddy lows and harsh highs to shape the tone of your track.
  2. Compression: For controlling dynamics. Not sure what compressing means? Read up here.
  3. Saturation: If you’re eager to use a plugin like Waves Kramer, this is where you can add some subtle warmth and brightness to your nearly-ready track.
  4. Stereo imaging: For widening or narrowing the stereo field without sacrificing the frequencies at the edges of your track. iZotope Ozone Imager or brainworx bx_digital V3 are great options here.
  5. Limiting: For ensuring your track doesn’t require a listener to turn the volume up or down based on the track before it on their listening platform—that is, unless they turn it up just because they want it to be louder!
  6. Metering: This represents your final check. Often highly visualized, this is where you conduct your final pass before export.

Now, it’s time to get to work in the DAW. With the right setup, your Pro Tools mastering workflow can deliver the polish, clarity, and impact that sets your music apart. So, take your time and remember that it’s just as important to identify the plugins that don’t serve your sound as it is to discover those that contribute to your sonic signature. Happy mastering!
