BoomComb VST

BoomComb is a tuneable comb filter VST2.4 plugin. Now you may ask what is a comb filter? Well a comb filter a delay based effect where it feeds back a delayed version of itself. Because of this it can create an effect similar to a flanger and can also give resonation type effects. The delay time of the comb is specified in Hz rather than time allowing the delay time to be set via MIDI input from a key press or using the pitch wheel, this allows the effect to be played like an instrument.

In the feedback loop of the effect is a damping filter which allows you to soften the sound of the comb. There is also Saturation in the feedback loop which can also be overdriven to dirty up the sound. You can also control the length of the resonation via the decay control.

Finally the output to the comb can mixed mixed with the input and is controlled by the dry/wet knob.

BoomComb can be used as like a flange like effect or can be used like a resonator with the frequency controlled by midi. It can also be used to create string like sounds via inputting noise in it. Another use is it can be used to add space to a sound and can be useful for spicing up synthetic drum sounds to make them sound a little more interesting.

The new 1.1 version has been rebuilt so that the GUI version can now support windows XP. Also there is a load of new presets provided by the talented Groove Criminals. As well as that the feedback control has been changed into a decay control to control the length of the resonation. Along with all this there are many bug fixes and optimizations.

BoomComb comes in 2 versions for download. The first version is optimized for Vista SP2 and Windows 7 using the latest drawing API, whilst the other is for targeting Windows XP SP3 and above.

    • Tuneable Comb Filter controlled via MIDI or knob.
    • Damping Filter in Feedback to reduce the harmonics or resonation
    • Decay control
    • Saturation in feedback loop for dirtying a sound or to be used subtly to add character
    • Custom GUI designed by Leonard  "paniq" Ritter
    • Uses custom GUI Framework with 2 builds one using the legacy drawing API and the other using the latest.

If you're curious as to how it sounds here is a preview made by the excellent Ronny Ragtroll using Ableton Live, the beat cutter, and BoomComb. There is also another preview from Rachel from The Flipside forums doing a Didgeridoo sound using BoomComb to manipulate it.
