UFO Filter

UFO Filter by pica Audio is a stereo filter plugin built for movement and character. Its analog-style filter core switches between low-pass, notch, and high-pass, with resonance that reaches self-oscillation. A multi-waveform LFO modulates cutoff or resonance, either free-running or tempo-synced, for rhythmic pulses or loose organic sweeps. Drive adds saturation directly in the filter path, from subtle warmth to aggressive grit, interacting with resonance for extra bite. A Mix control blends the filtered signal with the dry path, while output trim and true bypass keep things practical. The result is expressive, evolving filtering that goes beyond static tone shaping. It suits producers working on drums, synths, guitars, vocals, or experimental soundscapes who want pulsating, otherworldly textures in FL Studio, Ableton, or Logic.
