Dub Filter - High Pass for iOS: Limited-Time App Store Discount

Dub Filter - High Pass for iOS is currently available at a limited-time discount, dropping from $14.99 to $7.99—a 47% savings of $7.00. This productivity app is a meticulously modeled filter plugin inspired by King Tubby’s iconic Big Knob, a passive high-pass filter that defined the sound of roots reggae and dub music. It offers eleven frequency steps from 70Hz to 7.5KHz, plus controls for Impedance (resonance), Magnetism, Character, Dynamics, and Artefacts, allowing for everything from clean cuts to gritty, analog-style filtering. Two modulation sources—LFO and Envelope Follower—add rhythmic and dynamic movement, making it a versatile tool for sound designers and music producers. As a productivity app, Dub Filter stands out in the music production niche. While many filter plugins exist, few capture the specific character of vintage hardware with such authenticity. The AUv3 and standalone support mean it integrates seamlessly with iOS DAWs like GarageBand or AUM, or can be used on its own for quick experimentation. At half price, this is an excellent opportunity for producers who want to add a touch of classic dub flavor to their toolkit without breaking the bank. If you create electronic, reggae, or experimental music, this filter offers unique sonic possibilities worth exploring during the sale.
