Filterstation 2 is the Audio Damage dual filter, built for sound design and performance rather than corrective EQ. It runs two resonant filters in series, in parallel, or split across the stereo field, with twelve filter algorithms and a full set of modulation tools for movement, distortion, and rhythm. FEATURES Twelve filter algorithms, including our 914 bandpass and Filterpod lowpass models, a clean state-variable filter, and an MS20-style filter, covering lowpass, highpass, bandpass, and notch. Each of the two filter slots can run a different one. Serial, parallel, and true stereo routing. Run the filters one into the next, side by side, or split hard left and right. Envelope follower with stereo sidechain. Drive the cutoff from a signal's own dynamics for auto-wah, or feed in an external source so one track opens the filter on another. LFO with twelve patterns, internal or tempo-synced. VCA mode for tremolo and gating. FSU section for extra signal hacking, for when clean is not the point. Resizable vector interface, sharp on every iPhone and iPad display. Universal preset system. XML-based presets move between iOS and the desktop versions. IN USE... Sweep the cutoff by hand for 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 to duck a pad or bassline in time. Run the two filters in series for steep 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. Filterstation 2 runs as an AUv3 plugin inside any compatible iOS host, including AUM, Cubasis, Drambo, apeMatrix, and GarageBand. It is also available for macOS, Windows, and Linux as a desktop plugin, and presets move freely between them. Requires iOS 13 or later. An AUv3 host app is recommended. Features . Twelve different filter algorithms, including MS20 emulation and our classic 914 bandpass and Filterpod lowpass models. . VCA mode for tremolo and gate effects. . LFO with twelve different patterns, and both internal and tempo sync modes. . Envelope follower for dynamic control of filter frequency. . Serial, parallel, and true stereo operating modes. . Easy-to use interface for quick programming. . Vector-based resizable GUI. Use just the filter screen, slide the controls over it, or (in hosts that allow it) open up the whole UI. . Cross-platform XML-based preset manager; copy your desktop presets to the iOS version using Handoff, or share them with your friends and in forums. . Full PDF manual available at Support link.

Filterstation2 version 2.3.0
Updated At: 2026-10-08
Changes: Version History Filterstation 2 gets a workflow overhaul in this update:
- A brand-new preset browser, now with favorites, so the patches you actually use are one tap away.
- Smooth, click-free master Bypass for clean A/B comparisons.
- New VISUAL selector: a waveform display, a spectrum analyzer, or off.
- The Filter LFO and Envelope amount sliders are now properly bipolar.
- Envelope Attack and Decay sliders give finer control at the low end.
- Doubled the available LFO and envelope modulation depth. Your existing presets are preserved.
- Refreshed About box with web, Discord, and support links. 2.3.0 Jun 16 > > SIDECHAIN INPUT
For AUv3 hosts that have sidechain capability, Filterstation 2 is now a destination. You'll see a new "SIDECHAIN" button on the Envelope panel; this switches the envelope source from the main inputs to the sidechain input. For hosts that do not have sidechain capability (which is most of them) it will effectively turn off the envelope follower.
> > NEW PRESET MANAGER
Filterstation 2 has received the new-style preset manager we created for Continua, and are rolling in to most of our products. Your user presets may be in a little bit of a funky place, if you have saved any. You may need to re-save them in a new folder.
> > BUG FIXES AND OPTIMIZATIONS
The behind-the-scenes crap you won't notice at all that is really difficult and usually the most time-consuming part of any update, but makes for a terrible bullet point. Filterstation 2 is built with all the latest SDKs, APIs, and other three-letter things we use. 2.1.0 07/23/2020 Version 2.0.5 is a maintenance update, to ensure Filterstation is fully compatible with new additions to iOS, and to maintain parity with the desktop versions. 2.0.5 07/19/2019 2.0.4 01/04/2018
