Filterstation 2 is a dual resonant filter plugin by Audio Damage for macOS, Windows, Linux, and iOS. It runs two filters in series, in parallel, or split across the stereo field, with twelve filter algorithms covering lowpass, highpass, bandpass, and notch responses, including our 914 bandpass and Filterpod lowpass models, a clean state-variable filter, and an MS20-style filter. An envelope follower with stereo sidechain input drives the cutoff for auto-wah and ducking, an LFO with twelve patterns adds tempo-synced or free-running movement, a VCA mode handles tremolo and gating, and the FSU section is there for when clean is not the point. It is the Audio Damage take on the serial/parallel/stereo dual-filter topology the Sherman Filterbank made famous, rebuilt from the ground up with a resizable vector UI and a cross-platform preset system. Available as VST3, AU, AAX, and CLAP for desktop, and AUv3 for iPhone and iPad. Priced at $39 USD with no DRM, no subscription, and a perpetual license.

Features
-
Twelve filter algorithms — A clean state-variable filter, our 914 bandpass and Filterpod lowpass models, an MS20-style filter, and more, covering lowpass, highpass, bandpass, and notch. Load a different algorithm into each of the two filter slots.
-
Serial, parallel, and true stereo routing — Run the two filters one into the next, side by side, or split hard left and right. Same two filters, three very different jobs.
-
Envelope follower with stereo sidechain — Drive the cutoff from a signal's own dynamics for auto-wah, or feed an external source into the sidechain so one track opens the filter on another.
-
LFO with twelve patterns — Internal or tempo-synced. Ramps, steps, random, and a few shapes that do not have polite names.
-
VCA mode — Turns the filter section into a tremolo and gate for rhythmic chopping and amplitude tricks.
-
FSU section — Extra signal hacking for when clean is not the point. Push a sound until it stops behaving.
-
Resizable vector UI — HiDPI and Retina aware, scales cleanly from a laptop panel to a large display.
-
Universal preset system — Cross-platform XML-based presets compatible across all plugin formats and operating systems.
Sound Design Ideas
Sweep the cutoff by hand for classic filter rises and drops. Set the envelope follower to track the input for an auto-wah that moves with your playing. Patch a kick into the sidechain and let it duck a pad or bassline in time. Run the two filters in series for steep, vocal formant shapes, or in parallel for wide dual-band sweeps. Tempo-sync the LFO for rhythmic gating, then bring in the FSU section when the part needs to fall apart. Drop it on a drum bus for movement, or across a full mix for a filtered breakdown.
Frequently Asked Questions
What is Filterstation 2?
Filterstation 2 is a dual resonant filter plugin: two filters you can run in series, in parallel, or split across the stereo field. It includes twelve filter algorithms, an envelope follower with stereo sidechain input, an LFO with twelve patterns, a VCA mode for tremolo and gating, and an FSU section for signal mangling. It is built for sound design and performance filtering rather than corrective EQ. It is the Audio Damage take on the serial/parallel/stereo dual-filter topology the Sherman Filterbank made famous.
What filter algorithms does Filterstation 2 include?
Twelve in total, covering lowpass, highpass, bandpass, and notch responses across several models. These include our 914 bandpass and Filterpod lowpass models, a clean state-variable filter, and an MS20-style filter. Each of the two filter slots can run a different algorithm, so you can mix and match across the routing modes.
What do the envelope follower and sidechain do?
The envelope follower reads the dynamics of a signal and uses them to move the filter cutoff. Point it at the track's own audio for an auto-wah that follows your playing, or feed an external source into the stereo sidechain input so one track controls the filter on another. It is the same idea as sidechain ducking, applied to the filter instead of a compressor.
Does Filterstation 2 work on Linux?
Yes. Filterstation 2 is available as CLAP, VST3, and LV2 for Ubuntu 20 and later. macOS, iOS, and Windows builds are also available. All Audio Damage plugins are released for Linux alongside macOS, iOS, and Windows.
What plugin formats does Filterstation 2 support?
CLAP, VST3, and AAX on Windows 10 or newer. CLAP, VST3, AAX, and AudioUnit on Intel and Apple Silicon macOS 10.13 or newer. CLAP, VST3, and LV2 on Ubuntu 20 or later. AUv3 on iOS 12 or later. All desktop builds are 64-bit.
What makes Filterstation 2 different from a standard filter plugin?
A channel filter or EQ band gives you one filter for shaping or correction. Filterstation 2 gives you two filters with flexible routing, twelve algorithms, an envelope follower with sidechain, an LFO, and a VCA mode, so the filter becomes a sound-design and performance tool. It is the filter you reach for to add movement, distortion, and rhythm, not to fix a frequency problem.
Does Filterstation 2 use copy protection, require a subscription, or need iLok?
No. Like all Audio Damage products, Filterstation 2 uses no copy protection of any kind. You can install your purchase on every machine you own. It is a perpetual license, not a subscription, and there is no online activation requirement after install.
