Sheen Machine Crossgrade from Anthology XII, SplitEQ or Physion Mk II

Sheen Machine is an effects plugin from Eventide that adds smooth, airy high-end to vocals, synths, and other instruments without the harshness or sibilance of a traditional high-shelf boost. Built on Eventide’s patented Structural Split technology, it separates incoming audio into transient and tonal layers, then applies specially crafted EQ curves to each independently. This lets you enhance dull recordings, rebalance mixes with surgical precision, or add vocal sheen that helps a track shine. The single-knob workflow distills the power of SplitEQ into one simple gesture. It suits hobby producers and mixing engineers working in FL Studio, Ableton, or Logic who want a fast, musical way to brighten sources while keeping transients and sibilance under control. Use it for repair, enhancement, or creative rebalancing on any signal that needs more brilliance without edge.
