pure:unmask: Sidechain-Driven Mix Clarity Plugin by sonible Free Download

The plugin sits on the channel you want to sculpt, the background track, and takes a sidechain input from the channel you want to unmask, the prioritized track. Once the routing is connected, pure:unmask analyzes both signals and applies its processing to create separation between them.

Setup is light. You load the plugin, route the sidechain, and select a profile that fits the sidechain signal. The developer states that the processing aims to avoid pumping artifacts.

The Unmasking control is the large central knob and sets the overall strength of the effect. Resolution sets the width of the spectral processing bands. Speed changes the attack and release times, so you can tailor the effect to slower, harmonic sources such as piano against guitar, or to faster, rhythmic pairs such as kick against bass.

The Range control limits the unmasking to a chosen low and high frequency window, which helps when the overlap sits in a specific part of the spectrum.
