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.

Read full description

With up to four fully stereo chorus voices, BLEASS Chorus can create everything from subtle movement and gentle thickening to rich, complex modulations, while offering precise control over stereo width, prominence and intensity. In high-pass mode, the input filter is perfect for bringing out the space and airiness within a sound, before the advanced modulation engine makes that airiness shimmer and dance. Switching the filter to shelving mode opens up a whole new range of possibilities, from deliciously warm thickening effects to sparser, thinned-out lo-fi modulations. The detailed and colourful oscilloscope at the centre of the BLEASS Chorus interface shows you at a glance exactly what the plugin is doing. Thanks to the super-efficient BLEASS processing engine, this helpful visualisation won’t come at the expense of your system’s resources. More information and technical specifications available on https://www.bleass.com/chorus/ BLEASS Chorus can be launched as an AUv3 plugin or as a standalone app. BLEASS Chorus is also available for Windows and macOS.
