Filterjam

AudioThing Filterjam is a multi-band resonant filter plugin for producers who want to move beyond familiar filter sweeps. It splits incoming audio into four bands, then sums or multiplies them according to the selected mode, creating unusual textures with a ring modulation-like character. The results can range from gentle tonal changes to harsh, mangled sounds. Use it to bring extra brightness or depth to synth parts, or push acoustic recordings into more experimental territory. Its lightweight CPU footprint makes it a practical choice for everyday production, while the preset system and randomizer offer starting points for exploration. Filterjam suits hobby producers and sound designers looking for an approachable way to reshape audio. It supports Windows and macOS in 64-bit VST, AU and AAX formats.
