FilterFreak

The deal

$39.04 at Loot Audio (down from $149). Sale ends April 29, 2026.

What it is

FilterFreak is a resonant analog filter plugin from Soundtoys built to emulate the warmth and character of classic hardware filters. It covers everything from silky LFO sweeps and envelope-follower auto-wah to punchy rhythmic filter patterns locked to tempo, with a built-in rhythm editor that sets it apart from basic filter plugins. The bundle includes both FilterFreak 1 and FilterFreak 2, the latter adding a second filter path for stereo and parallel filtering.

Who it's for

Producers who want analog filter movement in their tracks - whether sculpting synth leads with slow resonant sweeps, adding funk to drums with envelope-follower effects, or building hypnotic filter rhythms on loops and pads.

Key features

• Built-in rhythm editor lets you draw custom filter patterns synced to your track's BPM for precise rhythmic filtering
• Envelope follower tracks the dynamics of your audio to produce auto-wah and classic funk filter sounds
• Covers low-pass, high-pass, band-pass, and band-reject filter types with resonance control modeled on classic hardware
• FilterFreak 2 adds a second filter path for dual-filter processing, stereo effects, and more complex filter chains
