comb()

Category

Filter / Resonator

Description

Comb filter that creates harmonic teeth or resonant body effects. It is useful for string-like tones, metallic textures, resonators, and synthetic physical-model style color.

Arguments

• input: audio/control signal to process
• delay: normalized comb delay position
• feedback: comb feedback amount

Typical Values

Use small delay values and moderate feedback for playable resonances. Higher feedback creates stronger ringing and more obvious tuned coloration.

Example

comb(noise()*attack(2000), 0.02+0.05*param(2), 0.18+0.45*param(3))

Notes

Comb filtering can become very characterful very quickly. It works well for plucks, struck objects, resonant keys, and unusual body simulations.
