Verbos Electronics Bark Filter is a filter module for modular synthesizers in Eurorack format. In addition to the 12-band fixed filter bank, the module also has a voltage-controlled mixer. Since eachband has an individual envelope follower and a single output, the frequency bands can be modulated and tapped independently of each other.
12 steep-flanked bandpasses
The filters are 6th-order bandpasses with steep edges. Their respective signal level is indicated by yellow LEDs, which are also operated via the envelope follower.
Envelope follower and VC mixer
The decay time of the envelope follower is globally adjustable. A voltage-controlled mixer with sliders is available for summation, the features of which correspond to those of the Harmonic Oscillator.
