What Dub Filter does
The filter is based on the Altec 9069B High Pass Filter, a passive inductor-based T-network filter launched by Altec in the 60s that provided 18 dB/oct attenuation across 10 positions and became known as King Tubby’s Big Knob. AudioThing replicated the original behavior of the filter and expanded it with additional controls and modulation. The plugin is offered as VST3, VST2, AU, AAX and CLAP for Windows and macOS, with native support for Apple Silicon listed.
The main stepped Frequency knob sets the cutoff, and the Impedance and resonance controls shape the filter behavior. Three controls adjust behavior in depth, including Magnetism, which controls the non-linear response. Two modulation sources are included, an LFO with multiple waves and an Envelope Follower. A preset system with a randomizer is included. The plugin is linked to the filter sound of King Tubby’s MCI console and Altec gear.
Key features
- Stepped high-pass filter. The main Frequency knob moves through stepped positions that follow the original 10-position Altec 9069B layout.
- Impedance and resonance. Impedance and resonance controls adjust how the filter responds, and they change the character of the cutoff.
- Magnetism and non-linearities. The Magnetism control sets the non-linear behavior of the inductance modeling, and the inductance controls shape the depth of that response.
- LFO modulation. The LFO offers multiple waveforms for modulating the filter cutoff over time.
- Envelope Follower modulation. The Envelope Follower modulates the filter from the level of the input signal.
- Brightness and contrast controls. Brightness and contrast controls adjust the tonal balance of the filtered signal.
Compatibility
Dub Filter comes as VST3, VST2, AU, AAX and CLAP for Windows 7 and later and macOS 10.13 and later in 64-bit builds, with native Apple Silicon support listed and 4 GB of RAM required.
