Brilliance Without Harshness
Based on Eventide’s patented Structural Split™ technology, Sheen Machine makes it easy to accentuate the “airy” quality of any signal without adding nasty sibilance or harshness.
The secret behind Sheen Machine’s magic is its ability to separate the transient and tonal parts of any audio signal. It offers a new path forward for adding tonal high-end without boosting transients. Add vocal sheen, not sibilance. Add air, not harshness. Make dull signals shine.
Eventide’s Structural Split technology lets you surgically sculpt high-frequency content in ways never before possible.
The NEW Approach to Adding Tonal Sheen
Sheen Machine is a purpose-driven tool for adding smooth and airy high-end to sound sources without introducing the high-frequency harshness often generated by a traditional high-shelf boost. Using Eventide’s patented Structural Split technology, Sheen Machine provides a simple solution for resolving complex problems often introduced when adding “sheen” to a signal, allowing for independent control over the transient and tonal layers of a signal without implicitly impacting the entire audio signal like a traditional EQ would. Power users have been doing exactly this using the full-featured SplitEQ plugin. We’ve put the power of SplitEQ in Sheen Machine and reduced it to a single, powerful, one knob gesture.
Applications

Enhance
Sheen Machine makes it easy to add tonal high-end to an otherwise dull recording or add “airiness” to vocals helping them shine brightly in a mix.
Features
Structural Split
The beating heart of Sheen Machine, built on the same ground-breaking technology found in SplitEQ and Physion. Whatever instrument you process, Sheen Machine analyzes the incoming audio and separates these components into their respective Transient (noise, pops, mic plosives, vocal sibilance, attacks) and Tonal (sustained notes, harmonics, tone, ambiance) elements.
Sheen Machine uses this information to apply specially crafted EQ curves to the transient and tonal layers of the incoming audio, adding “airiness” and “sheen” without adding harshness.
Just One Knob
A straightforward user interface focused specifically on what matters: Adding tonal sheen to incoming audio. Turn the dial, hear the added sheen. The Sheen Machine user interface also includes undo/redo, input gain and built-in bypass.
