Verbos ElectronicsBark Filter Fixed Filter Bank

The Bark Filter Processor is a 12 band fixed filter bank with individual outputs and envelope followers on each band as well as a voltage controlled mixer for blending the outputs. The filters are steep, 6th order bandpass filters with yellow LEDs indicating the level at the envelope followers’ outputs. The voltage controlled mixer has sliders and individual CV ins and draws the, “center”, “width” and “tilt” controls from the Harmonic Oscillator allow- ing the fixed filters to be scanned across blended and mixed in various ways, all at the same time. The even and odd filters can be patched in and out separately and one side’s followers can control the other side’s levels like a vocoder.

Containing 12 fixed, ultra steep 6th order bandpass filters, the Bark Filter Processor has the ability to extract a wide-array of artifacts & tones from the input signal - especially with the use of its scanning circuitry (also seen on the Harmonic Oscillator)
For this video, we put together a special 208 HP system to showcase the Bark Filter Processor generating and processing
A harmonically rich signal from the Complex Oscillator was sent to the Bark Filter which was then, further processed through the Multi-Delay Processor which was on atmospheric and complex feedback duties. Borrowed from videos like LFO control I & II, the Voltage Multistage was used as a complex LFO generator which was controlling the “center” position of the scanning section.
Further, a key focus of this patch was the use of heavy handed, manual manipulation of the panel controls, since the Bark Filter was only “allowed” to pass through a narrow band of signal, it responded well to extreme adjustments of the sounds. The end result yielding a perfect soundscape for any horror film.
