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.

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.
