Comb Filter
Kilohearts
The Comb Filter hollows out the sound by carving out frequencies at each multiple of the base frequency, like the teeth of a comb.
The Comb Filter will mix the signal with a delayed version of itself, creating a filter with repeated troughs and peaks across the spectrum.
Snapins are isolated audio effect modules, each performing a specific task. The Kilohearts product lineup will allow you to combine these snapins in different ways in order to create interesting and unique combinations of effects.
Snapins can be loaded into your DAW as a standard VST or Audio Unit plugin, as well as into other Kilohearts plugins that can act as snapin hosts, for example Multipass.
The Comb Filter hollows out the sound by carving out frequencies at each multiple of the base frequency, like the teeth of a comb.
The Comb Filter will mix the signal with a delayed version of itself, creating a filter with repeated troughs and peaks across the spectrum. It’s also possible to process left and right differently in a way that not only gives a wide stereo effect, but also collapses right back to the original signal when mixed to mono. Nifty!
Cutoff display
Cutoff setting for the filter, the distance between each peak.
Polarity
The polarity setting swaps troughs for peaks and vice versa, with the plus setting having a peak at 0 Hz, and the minus setting a trough at 0 Hz.
Stereo
The stereo setting flips the polarity setting for the right channel, allowing the the comb filter to be used for mono compatible stereo widening.
Mix knob
The dry/wet mix of this effect. A lower value will let some of the unmodified signal through.
Settings panel
Whenever you have your mouse cursor over a snapin theree is a small arrow at the top right corner (not visible in screenshot). It opens a settings panel where you handle presets. It also has a “randomize” button that can be useful. I guess…
Enabled checkbox
The small checkbox to the left of the plugin name is a checkbox that bypasses the effect when disabled.
Resize handle
The bottom right corner of all Kilohearts plugins is a resize handle for scaling the UI to any size. This allows you to get a good view of the controls whatever the screen resolution, and also comes in handy if you need big controls, e.g. when using Comb Filter as a real-time effect on a touchscreen monitor during a live set. (This is not available when the snapin is used inside a snapin host.)

If you use a lot of snapins at the same time in your patch the CPU usage will increase accordingly. Thus, we cannot guarantee that the snapins will work flawlessly in all use cases even if your system does meet the minimum recommended system requirements.
