Sheen Machine

Sheen Machine is an audio effect plugin from Eventide that adds smooth, airy high-end to any signal 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 tailored EQ curves to each. This lets you enhance dull recordings, add vocal sheen, or bring vibrance to synths and instruments while keeping transients and sibilance under control. With a single, powerful knob, Sheen Machine delivers the core benefit of SplitEQ in a focused, easy-to-use tool. It’s ideal for hobby producers and mixing engineers who want to repair, rebalance, or enhance high-frequency content musically. Whether you’re brightening a vocal, adding air to a mix, or making dull signals shine, Sheen Machine offers a smooth, surgical solution for tonal sheen without the side effects.
