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.
REAMP
This audio effect processor simulates the sonic characteristics of various analog gear, offering seven distinct models. It's designed for high CPU efficiency and low latency, allowing for subtle or pronounced saturation across different audio sources and genres.
- Seven analog gear models
- Spectral saturation
- Low latency processing
- Dry/Wet mix control
- Factory presets
- Optional 8x oversampling

This effect is a complex spectral saturation processor simulating a set of different analog gear in a new and unique way. Benefits of this algorithm is that it is highly CPU efficient and adds (almost) no latency. The 7 models available are based on real analog gear individually measured in two dimensions; gain responses (-inf dB to +6 dB) at the frequency spectrum 20Hz to 20kHz. This data is used to transform input audio to output audio. Models: Cassette Deck A consumer cassette deck produced in the mid 80’s. This profile adds some nice grit in the lower mids and rolls off the higher spectrum in a very pleasant way. 1/4” Tape Reel A high quality tape reel machine was used for this profile. Set to one channel mode, there was plenty of dynamic bandwidth to capture on this one. Adds some subtle tape saturation that oozes mid 70’s. Preamp Tube Clean / Preamp Tube Drive These two profiles are captured from a high end tube microphone preamp with two different input gain levels (normal gain on the Clean version and a boosted level on the Drive version). Used on only one channel, this profile is very subtle, but the impact adds up when several channels are used simultaneously. Guitar Tube Clean / Guitar Tube Drive The guitar amp used is a well known pro amp used by several pro guitar players, and Just like the Preamp Tube profiles, these are recorded with two different input gain levels. Tube Bass Amp One of the developers friends dad had an old bass amplifier that we borrowed and profiled. Tip: Run a Fender Jazz bass through it and your neo soul licks will sound just like they’re supposed to. Usage: Since there are several models available, this one can be used on almost any type of audio in any genre. The output can span from lo-fi to high-end hifi. One approach is to put it on several tracks with a more subtle setting which makes the essence of the gear simulated add upp. Another is to put it on the mix, or a bus. Since we’re in the digital domain there can be some added aliasing when distorting the signal too much, resulting in an unpleasant high frequency boost. To prevent this, set the HARMONICS switch to SOME or FEW. Feature list • Seven handpicked profiles based on gear we love available. • Spectral drive (four bands) • Dry / Wet mix • Plenty of factory presets • Ultra low latency • Optional 8x oversampling Full documentation available inside the app or at https://klevgrand.se/downloads/reamp-docs/ REAMP works both as a standalone app and as an AUv3 plugin.
