"The BX True Peak Limiter sounds the way it looks: A slick design, easy to use, and the ability to go into more detail of control when tweaks are needed. The access to various monitoring options of the stereo signal is an awesome bonus."
. Mastering Engineer (Faith No More, Yes, Sepultura)
"I've always wanted to enjoy using a true peak limiter in my mastering work, but have had trouble finding one I really loved using, until now. The bx_limiter True Peak sounds as good as the best conventional limiters while making sure I avoid oversample peaks. I also love the unique tonal control found in the Foundation and XL saturation knobs, and have found myself using them so much more than I ever anticipated."
. Mastering Engineer (Yoke Lore, Brothertiger, Joshua Lee Turner)
"I am absolutely BLOWN AWAY at how great this new bx_limiter True Peak sounds. You can go super loud and super clean with this bad boy! Easy to navigate, easy to use... This a game-changer!"
. 15 Grammy Awards, 32 Grammy nominations

The first true peak limiter you will love listening to

bx_limiter TP (True Peak) from Brainworx is a completely new design, crafted to avoid the shortcomings of existing true peak limiters. Use it to confidently hit your loudness targets without leaving behind any distortion-inducing inter-sample peaks, and without compromising on the sound quality of your masters.

Designed from the ground up to be the ideal true peak limiter

Until now, most digital limiters that include a true peak mode have simply added it on as an afterthought. This has left a lot to be desired, with users complaining about unstable low end, compromised stereo imaging, harsh artefacts, and smeared transients. But with the bx_limiter TP, Brainworx has taken a new approach, designing the TP algorithm from scratch to make it perform and sound better than other digital limiters - while also eliminating troublesome inter-sample peaks for even cleaner results.

Selective Oversampling - two years in development!

With input and feedback from top mastering engineers around the world, Dirk Ulrich and the Brainworx engineers packed bx_limiter TP with new technology and new controls. It relies on “Selective Oversampling” (SOS), to employ oversampling only where it actually improves the signal, and to avoid it where it has been found to compromise the sound. Coupled with its “Advanced Look-Ahead” design and its incredible speed, it is able to deliver tighter, more accurate low end and better stereo imaging than any other true peak limiter around, even at extreme settings. And it is a true rockstar in preserving transients while increasing density and loudness. Punchy, loud & clear!

A complement of extra controls for enhanced final sweetening

The bx_limiter TP does more than just limiting peaks. It also includes simple yet powerful tools to add the finishing touches of sweetening, for a more perfect master. Onboard low and high pass filters help control the extremes, while proprietary “XL” saturation and “Foundation” filters can be used to add subtle degrees of heft, weight, tightness, or clarity to fine-tune the sound of your master. This is particularly important as it allows you to constantly adjust the vibe of your master while you’re turning up the volume to get to a competitive loudness. Even small details like a negative gain control have been implemented, which comes in handy when you have to correct mixes that suffer from less-than-ideal gain staging quickly and efficiently.

More metering than your average limiter

Also included is a suite of essential metering and monitoring options to help you better understand what’s going on within your audio. In addition to the traditional level and gain reduction meters, the bx_limiter True Peak includes a customizable loudness meter for hitting specific loudness targets, a correlation meter for checking phase coherence, and the ability to monitor the centre, sides, and L/R channels separately – even soloed in place.


  • Two different styles/sounds of limiting: Modern and Classic
