Epica Audio UFO Filter II

UFO Filter is a powerful stereo filter plugin built around advanced LFO modulation Its multi-waveform LFO modulates cutoff, resonance, and even morphs seamlessly between low-pass and high-pass filters, unlocking expressive and evolving sonic movement.

With organic, tape-like saturation, tempo-synced rhythmic control, and wide stereo processing, it goes far beyond traditional filter plugins - delivering everything from subtle rhythmic modulation to aggressive, pulsating effects.

From drums, synths, and guitars to vocals and experimental soundscapes, UFO Filter transforms ordinary sounds into expressive, extraterrestrial textures in seconds.

The truth is out there, and it sounds otherworldly.

Features

• At its heart is a versatile analog-style filter switchable between Low-Pass, Notch, and High-Pass, with resonance to emphasize the cutoff point up to the edge of self-oscillation. Simple, musical, and the foundation everything else in UFO Filter builds on.
• A flexible LFO engine modulates Cutoff or Resonance (Q) with five selectable waveforms, from smooth sine motion to stepped Sample & Hold. Sync it to the host tempo for rhythmic filter movement, or run it free for something looser and more organic.
• Drive adds saturation directly into the signal as it passes through the filter, layering in extra harmonic content and grit alongside the frequency shaping. Push it lightly for warmth, or hard for a dirtier, more aggressive character.
• A Mix control blends the filtered signal with the untouched dry path, keeping the effect as subtle or as extreme as the moment calls for. Output trim handles final gain staging, and a true bypass makes for a clean, fair comparison.
