What are the best filter plugins for creating movement and modulation effects in your mix?

1 LFO Filters

One of the simplest ways to create movement and modulation with filters is to use a low-frequency oscillator (LFO) to modulate the filter cutoff or resonance. This can create rhythmic patterns, pulsing sounds, or sweeping effects that sync to the tempo of your project. Some examples of filter plugins that offer LFO modulation are FabFilter Volcano, Soundtoys FilterFreak, and Cableguys FilterShaper.

2 Envelope Filters

Another way to create movement and modulation with filters is to use an envelope follower to modulate the filter cutoff or resonance based on the input signal level. This can create dynamic effects that respond to the intensity, attack, or decay of your audio source. Some examples of filter plugins that offer envelope modulation are Waves Enigma, Sugar Bytes WOW2, and Native Instruments Driver.

3 Sequencer Filters

A more advanced way to create movement and modulation with filters is to use a sequencer or a step modulator to modulate the filter cutoff or resonance with precise control over the timing, shape, and depth of each step. This can create complex and evolving effects that add variety and interest to your audio tracks. Some examples of filter plugins that offer sequencer or step modulation are u-he Filterscape, Arturia Filter M12, and Kilohearts Multipass.

4 Resonator Filters

A unique way to create movement and modulation with filters is to use a resonator filter to add harmonic resonance to your audio source based on a tuned frequency or a note input. This can create rich and musical effects that enhance the tonality, pitch, or melody of your audio tracks. Some examples of filter plugins that offer resonator filters are Ableton Resonators, Eventide Fission, and MeldaProduction MRhythmizer.

5 Morphing Filters

A creative way to create movement and modulation with filters is to use a morphing filter to blend between different filter types, shapes, or modes. This can create smooth and seamless transitions, or abrupt and dramatic changes, depending on how you control the morphing parameter. Some examples of filter plugins that offer morphing filters are Xfer Serum, Tone2 Icarus, and Zynaptiq Morph.

6 Comb Filters

A final way to create movement and modulation with filters is to use a comb filter to create phase cancellation or reinforcement between your audio source and a delayed copy of itself. This can create flanging, phasing, or chorus effects that add depth, width, or movement to your audio tracks. Some examples of filter plugins that offer comb filters are Valhalla Freq Echo, D16 Group Syntorus, and AudioThing Phase Motion.
