Oxford Envolution – HDX

Sonnox Oxford Envolution – HDX is a frequency-dependent envelope shaper that lets you adjust attack and decay with separate transient and sustain controls. Give drums extra definition, bring out the strike of a piano, or push percussive guitar parts further back in a mix. Broad tilt processing and a more focused, parametric-style mode let you target the frequencies you want to reshape rather than treating the whole signal equally. Raise sustain to reveal room sound and ambience, or reduce it for tight, gate-like control. For more adventurous production, the DIFF button isolates the effect and opens up negative-ratio compression textures. A Warmth control adds harmonic saturation and tonal character while helping contain excessive output levels. With phase-safe parallel use and presets for starting points, it suits producers who want practical punch shaping and creative envelope manipulation on tracks, buses or the master output.
