pure:unmask makes short work of one of mixing’s most vital components – finding space within one track for another – with minimal setup. All you have to do is load pure:unmask on the channel that needs to make space, route a sidechain input from the prioritized channel and then select a profile that fits the sidechain signal.

The processing can be refined via four controls. Unmasking is the large central knob that lets you increase or decrease the overall effect. Resolution allows you to define the width of the spectral processing bands at work. The Speed parameter lets you either shorten or lengthen attack and release times; effectively tailoring the unmasking effect to slower, harmonic contexts (piano vs guitar) or to faster, rhythmic contexts (kick vs bass). You can even restrict the unmasking process to within a given low-frequency and high-frequency range using the Range control.
