Sonnox Oxford Envolution Dynamics Plugin (Native AAX/VST/AU/RTAS)

Envolution is a frequency-dependent envelope shaper with separate transient and sustain sections to radically re-shape the sonic envelope of your instruments or audio. Use a broader tilt mode or the more parametric-style focus mode to choose which frequencies are processed. Insert on a track, bus or even master output to add presence/distance to drums, piano, guitar and any other percussive content. Boost sustain to make the ambience around a recording bloom, or cut it for quick and precise gating.

You'll love the more creative and extreme side of the plug-in too; like using the DIFF button to generate negative ratio compression effects!
