Umbra - Filter Bass Processor

Umbra is a comb filter bass processor built to turn plain low end into something wide, gritty and loud. Filter, distort and finish your bass in one clean window, with no menus to dig through.

WHAT'S INSIDE

FILTER

Four comb filter types with their own character:

• Razor – sharp, cutting, metallic

• Hollow – thin and resonant

• Cave – dense and layered

• Melt – smeared and unstable

Dial in cutoff, resonance, damping and drive, then add movement with speed and wobble modulation.

DISTORT

Four distortion types: Soft, Hard, Fold and Asym. Shape the sound with drive and tone, then roughen it further with sample-rate reduction and bit crushing.

LOW PROTECT

Keep your sub clean while everything above it gets destroyed. Set the crossover frequency and the low end stays solid underneath the grit.

AND MORE

• Factory presets: Nazareth, Radiator, Phantom, Malfunction, Amp and Laser, plus a clean default to start from

• Live visuals: filter response, scope, spectrum analyzer and waveform

• Three color themes: Umbra, Obsidian and Amber

• Resizable window

• Output and master mix controls

Your purchase includes both the Mac and Windows versions, so you can use whichever you need. Each zip comes with the plugin, a README with install steps, and the license.

INSTALLATION

Install steps are in the README inside each download. Umbra is not code-signed or notarized, so macOS or Windows may show a warning the first time you install or load it. The README explains the quick fix for each.
