Overview

Remove harshness from vocal and instrument recordings

bx_refinement is a plugin that removes harshness from your recordings without negatively impacting articulation, clarity, and detail. When you adjust the plugin’s large Damping knob, it targets and reduces unpleasant frequencies in vocals and instruments, making it an essential tool for mixing and mastering. Use this plugin to improve edgy vocals and improve the sound of harsh cymbals, spiky acoustic guitars, and resonant masters.

Add warmth to your audio with analog tube saturation

Experience a unique combination of harshness smoothing and analog tube saturation. Rather than emulating a single piece of hardware, bx_refinement combines several desirable musical characteristics of audio enhancement found in tube-based equipment. Enrich your sound with saturation, then infuse it with a sense of openness using the built-in shelving filter.

Choose between subtle or surgical enhancements

Adjust the character of the processing applied with bx_refinement by choosing between second-order filtering (Soft) or fourth-order filtering (Hard). With a gentle slope, second-order filtering preserves the natural character of your audio, making it ideal for subtle enhancements. Fourth-order filtering applies sharp frequency cuts and provides a more defined sound, best suited for severe audio issues.

Apply dynamic and groovy modulation for an organic feel

The Dynamics and Oscillator options allow you to modulate the smoothing (Damping) effect applied to your recordings. Intelligently adjust the de-harshing filter based on the input signal’s peak level using the Dynamics option. Additionally, use the Oscillator section to create rhythmic warming effects that perfectly sync with the tempo of your track.

    Since a majority of my chain consists of analog gear, I'm very selective when it comes to which plugins I use. bx_refinement has definitely been a great addition to my arsenal.

    I love this on the mix bus. I use a lot of amp sims, and I get a buildup of harshness in the upper end, typically. This plugin corrects that, and simultaneously adds some analog mojo to the mix with… Read More

    I remastered an old 4-track recording and after several treatments I had a "staircase" effect on the signal. Refinement allowed me to sweeten the signal with the "analog" charm
