Filterjam
Key Features
- Divides incoming audio into four resonant bands that can be summed or multiplied for complex filter interactions.
- Creates sounds from subtle brightness and depth through to metallic, ring-mod-like textures.
- Offers up to 16x oversampling for the creative filtering engine.
- Uses a lightweight CPU design for fast experimentation across tracks and effects chains.
- Includes a preset system and randomizer for discovering unpredictable variations quickly.
- Provides 64-bit VST2, VST3, AU, AAX, and CLAP support where those formats apply to the platform.
Description
Filterjam is a four-band resonant filter for turning ordinary audio into moving, metallic, and ring-mod-like textures. It splits the input into four bands, then sums or multiplies them in the selected mode, so the result can range from gentle brightness and depth to deliberately mangled sound.
A large frequency control, emphasis, gain, mix, and a mode switch keep the core workflow immediate instead of surgical. The included randomizer and preset system make it useful for quickly finding unusual variations on synths, drum loops, guitars, vocals, and sampled material.
Its 16x oversampling option and lightweight CPU design make it practical to audition as a parallel color effect, where the Mix control can preserve the source while adding resonant detail. The character is intentionally strong, so it is best treated as a creative transformation for a section, transition, or sound-design layer rather than as a corrective mix filter.
Filterjam supports current 64-bit desktop hosts on Windows, macOS, and Ubuntu, including VST2, VST3, AU where applicable, AAX where applicable, and CLAP. AudioThing also provides an iOS/iPadOS edition separately, but this entry covers the desktop plug-in download supplied through the developer's email form.

Frequently Asked Questions
What does Filterjam do differently from a standard filter?
Filterjam processes the input through four resonant bands rather than a single conventional cutoff path. Its sum and multiply modes can create complex interactions that lean toward metallic or ring-mod-like color instead of straightforward tonal cleanup.
Is Filterjam suitable for precise corrective EQ work?
No. Its controls and band interactions are intended for character, movement, and transformation rather than surgical frequency correction. It works especially well as a parallel effect or for an intentional transition or texture layer.
How do I get the desktop download?
AudioThing provides the desktop download links through the named email form on the exact Filterjam product page. The page identifies Filterjam as freeware and states that no internet connection is required to activate the plug-in after download.
Which desktop systems and plug-in formats does it support?
The official page lists Windows, macOS, and Ubuntu 20.04 LTS support. Format availability is platform-specific: VST2, VST3, AU, AAX, and CLAP are listed across the supported desktop systems.
