Motion Filter by Denise Audio

Bringing static tracks to life and injecting organic movement into your mixes is remarkably straightforward with Motion Filter by Denise Audio. Re-imagining their cult-classic Sweeper plugin, this state-of-the-art filter processor is designed to animate any sound source without requiring tedious automation lanes or complex routing setups. Whether you want to add subtle, breath-like motion to acoustic elements or craft dramatic, rhythmic sweeps across electronic drops, Motion Filter delivers pristine audio quality and an obstacle-free workflow.

Dual Modulation Modes for Sweeper and LFO Movement

At the heart of the plugin are two flexible modulation engines tailored for different creative needs. Sweeper mode utilizes an advanced envelope follower that links filter movement directly to the dynamic peaks and valleys of your incoming audio, allowing percussion, loops, and vocals to drive their own rhythmic filtering naturally. Alternatively, LFO mode applies pre-programmed waveforms that sync directly to your DAW's host BPM, letting you craft recurring cinematic sweeps, smooth undulating pulses, or sharp rhythmic chops with complete precision.

Precision Filtering and Flexible Slopes

Motion Filter goes far beyond basic EQ cuts by offering a complete suite of professional filter shapes, including low-pass, high-pass, band-pass, and notch configurations. You can dial in exact frequency boundaries using start and end points, flip the direction of the sweep, and select filter slopes ranging from a gentle 12 dB per octave all the way up to a surgical 96 dB per octave. For added character, engage the dynamic resonance feature to make the filter resonance evolve dynamically alongside the movement.

External Sidechaining and Streamlined Integration

Designed to fit seamlessly into fast-paced studio sessions, the plugin features built-in external sidechaining capabilities so you can trigger filter motion from independent sources like a kick drum or snare. Coupled with dry-mix blending, adjustable attack and release timings, and native compatibility across major plugin formats on macOS and Windows, Motion Filter offers a frictionless way to add professional depth, excitement, and character to your entire mix.
