DubFilter is a dual low-pass/high-pass filter effect with resonance and an exclusive Overlap parameter, designed for real-time audio processing. It operates as an AUv3 plugin and standalone app on iPhone and iPad, focusing on dub-style filtering for electronic music. For iPhone and iPad music making, it integrates into DAWs via AUv3, allowing users to modulate cutoff and resonance with LFOs or envelopes for dynamic effects.
The app’s simple interface supports MIDI learn and preset management, making it suitable for live performances and studio mixing. Its iOS-exclusive design provides low-latency filtering for mobile producers.
