The best sounding True Peak Limiter available
The bx_limiter True Peak from Brainworx is a completely new design, crafted to avoid all the shortcomings of other true peak limiters. Use it to confidently hit your loudness targets without leaving behind any distortion-inducing intersample peaks, and without compromising on the sound quality of your limiter.

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 of unstable low end, compromised stereo imaging, harsh artifacts and more. But with the bx_limiter True Peak, Brainworx has taken a new approach, designing the plugin from scratch to perform as well or better than any conventional digital limiter while also eliminating troublesome intersample peaks for even cleaner results.

Two years in development, tested and approved by mastering professionals
With input from top mastering engineers around the world, Dirk Ulrich and the engineers of Brainworx packed bx_limiter True Peak with new technologies 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.

A complement of extra controls for enhanced final sweetening
The bx_limiter True Peak does more than just limit 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.

More metering than your average limiter
Also included are a suite of essential metering and monitoring options to help you better understand what’s going on with 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 center, sides, and L/R channels separately or solo’d in place.

    There was a noticeable difference between this limiter and all the other limiters I was using. Completely transformed the sound. Also using it oversampled makes it even better. Highly recommended.
