We’re currently living in the age of digital audio, and in-the-box mixing within a digital audio workstation is commonplace. Plugins are, therefore, invaluable assets for the modern audio engineer. Limiters are also an important tool in the audio engineer’s toolbox. With so many limiter plugins on the market, 10 stand out as being top performers.
What is audio limiting? Limiting is a type of hard compression whereby the signal is not allowed above a certain threshold. Rather than attenuating the signal (above the threshold) by a ratio, the limiter will cut off the signal at the threshold. We can think of a limiter as a compressor with an infinite ratio.

In this article, we’ll discuss the top 10 best limiter plugins.
The top 10 best limiter plugins for digital audio workstations are:
- FabFilter Pro-L 2
- Waves L3 Multimaximizer
- Softube Weiss MM-1
- iZotope Ozone 9 Maximizer
- Sonnox Oxford Limiter V3
- Nugen ISL 2
- IK Multimedia T-RackS Brickwall Limiter
- Tokyo Dawn Labs Limiter 6 GE
- Brainworx bx_limiter
- Universal Audio Precision Limiter
It should go without saying that any “top X” article is subject to bias. I would expect the next person’s top 10 to be different than mine but hope that there would be plenty of overlap.
That being said, I believe these plugins to be the best limiter plugin options today. The criteria I used to judge these plugins include the following:
- Sonic performance: how does the limiter plugin sound subjectively/objectively?
- Graphic user interface (GUI): how does the limiter plugin look when loaded in the DAW?
- Ease-of-use: how user-friendly is the distortion plugin?
- Functionality: how many different functions does it serve and/or how many parameters are available for the limiter effect?
- Accessibility/compatibility: how easy is it to acquire the limiter plugin and what are the system requirements?
Let’s discuss each of the top 10 best limiter plugins in greater detail to learn why they made this list.
FabFilter Pro-L 2
The FabFilter Pro-L 2 (link to check the price at Plugin Boutique) is a feature-rich limiter plugin that outperforms the competition in practically all applications.

The Nugen ISL 2 (link to check the price at Plugin Boutique) a transparent lookahead peak limiter with a straightforward design and superior sonic performance.
The Nugen ISL 2 is compatible with Mac OS and Windows OS and comes in AAX, AU and VST formats.
The True Peak algorithms of the ISL 2 meet various standards (including ITU-R B.S. 1770 and Apple ‘afclip’). From transparent limiting to dithering, this plugin does a fantastic job transparently boosting the perceived loudness of the signal while protecting from digital overloading/clipping.
Unlike traditional limiters, Nugen Audio’s ISL 3 provides a TPlim control, which automatically adjusts the transfer curve parameters for minimally invasive brick-wall limiting protection. Whether we’re keeping broadcast levels safe or mastering the next big musical hit, this plugin is ready for the job. The ISL 2 even offers Surround compatibility up to 7.1.2.
Low-frequency content is managed easily with auto-release monitors, ensuring low-end transients don’t cause overt pumping in the signal.

Tokyo Dawn Labs Limiter 6 GE
The Tokyo Dawn Labs Limiter 6 GE (link to check the price at Plugin Boutique) is a modern dynamics compression and limiting toolkit with 6 specialized modules, all involved with the process of compression/limiting.
The Tokyo Dawn Labs Limiter 6 GE is compatible with Mac OS and Windows OS and comes in AAX, AU and VST formats.
I almost left this “limiter” off the list. However, since the multi-module plugin is so focused on providing flexible limiting, I decided to add it after all.
Set the 6 modules of the Tokyo Dawn Labs Limiter 6 GE in any order to achieve a wide range of results, spanning from subtle loudness control to brickwall limiting to creative mix bus compression. These 6 modules include:
- Dynamics Compressor
- High-Frequency Limiter
- Peak Limiter
- Output Protection Limiter
- True Peak and EBU Loudness Meter
Each of the modules works together to provide an incredibly flexible and versatile mastering tool. Looking at the plugin as a whole, it’s certainly deserving of a spot on the best limiter plugins list. Dial in each module to the need of the project and enjoy maximized loudness with superior musical fidelity, punch, and excitement.
For more information on system requirements and authorization instructions, check out the Limiter 6 GE user manual.
The Brainworx bx_limiter (link to check the price at Plugin Alliance) is a finely crafted limiter algorithm designed for master chains, mix buses, and individual tracks alike. From super-transparent master limiting to beautiful saturation/compression, you can depend on this plugin across multiple instances in your DAW.
The Brainworx bx_limiter is compatible with Mac OS and Windows OS and comes in AAX DSP, AAX Native, AAX AudioSuite, AU and VST formats.
Brainworx developed this superb plugin to use on multiple mix buses to really glue the mix together before the master channel. Multi-stage parallel and series compressions will help increase the overall loudness of a mix, and multi-stage limiting will do so, perhaps even more efficiently.
To facilitate the use of multiple instances, the bx_limiter is extremely CPU-friendly. The accurate limiting can be used on mono, stereo and multi-channel/Surround signals. Though Brainworx itself suggests the bx_XL V2 or bx_masterdesk limiters on the master channel, the low-latency bx_limiter also works amazingly well as the final mastering limiter.
Powerful features of the bx_limiter include a Channel Link knob, which seamlessly blends between unlinked and linked peak detection and a Mix control for parallel processing.
For more information on system requirements and authorization instructions, check out the bx_brainworx user manual.
Brainworx is featured in My New Microphone’s Top 11 Best Audio Plugin (VST/AU/AAX) Brands In The World.
Universal Audio Precision Limiter
The Universal Audio Precision Limiter (link to check the price at Universal Audio) is a premium performance brickwall limiter from none other than UAD.
The Universal Audio Precision Limiter, like all UAD plugins, requires UAD hardware to function with your DAW. UAD hardware is compatible with Mac OS and Windows OS, and the plugins are available in AAX, AU and VST formats.
This single-band brickwall limiter is designed for colourless, transparent mastering. It features superb lookahead control to ensure no peak exceeds the set output limit, making it perfect as a protection tool and a loudness maximizer.
The Precision Limiter works its magic with any upsampling or filters. If it has to compress, the audio, it does so with precision and clarity. If not, then the audio is passed completely unaffected.
The character can be altered slightly with the Contour Mode, which adjusts the attack, shape, and character of a limiting process. However, in terms of timbre, this limiter is about as clean as they come.
For more information on system requirements and authorization instructions, check out the UAD Plug-Ins Manual.
