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

Eventide says Sheen Machine analyzes each incoming signal and divides it into a transient layer, which covers noise, pops, plosives, vocal sibilance and attacks, and a tonal layer, which covers sustained notes, harmonics and ambience.

EQ curves are then applied to each layer separately. The tonal layer receives the added air, while the transient layer is treated differently, so high-frequency energy is not boosted across the whole signal. The developer presents this as the reason the plugin can add sheen to vocals or dull recordings without the sibilance a traditional high-shelf boost can bring out.

Because the process is built on the same technology as SplitEQ and Physion, the developer describes Sheen Machine as a focused version of those tools.

Sheen Machine uses a single dial. Turning it adds tonal sheen to the incoming audio, so you can hear the result immediately without working through several band controls.

The interface also includes undo and redo, input gain and a built-in bypass, which makes it quick to compare the processed and unprocessed sound while setting the amount.

The design suits producers who want a fast brightening step on vocals, synths and other instruments during mixing rather than detailed surgical EQ.
