Official effect
Short-delay comb filter with LFO-modulated delay time for metallic, resonant flutter.
The core feeds the input through a low-passed feedback comb whose delay time is moved by a sine LFO. `focus` sets the base delay and post-filter high shelf, `motion` increases both delay modulation depth and feedback, and `rate` sets sweep speed, so the result behaves like a resonant flanger-like comb texture rather than a conventional filter bank.
Static peaks come from the compiled FAUST preview render. The live scope is drawn from the browser playback output in real time.
How It Works
The core feeds the input through a low-passed feedback comb whose delay time is moved by a sine LFO. `focus` sets the base delay and post-filter high shelf, `motion` increases both delay modulation depth and feedback, and `rate` sets sweep speed, so the result behaves like a resonant flanger-like comb texture rather than a conventional filter bank.
Signal Path
Preview source: An internally generated picked-string phrase is widened to stereo with a 19-sample right-channel delay and slight left/right shelf-EQ offsets before it hits the filter core.

Feedback comb filter with LFO-modulated delay time and post-filter high-shelf tone shaping.
The static waveform and the live player both reflect this compiled signal chain.
These are the currently active controls detected in the FAUST source for this effect.
The generated description is tied to the active helper blocks and routing found in the current DSP.
Controls
Blends the untouched stereo preview source with the filtered path after the effect core.
Lower settings preserve more dry attack and full-band tone; higher settings emphasize the filter treatment.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the filter behavior itself.
Sets the base comb delay time and the post-filter high shelf.
Moves the comb spacing and changes how bright the comb texture feels.
Increases delay-time modulation depth and comb feedback.
Makes the comb more animated and more resonant.
Sets the speed of the internal LFO that modulates the comb delay time.
Changes how fast the metallic sweep moves.
Analysis
Current implementation is a distinct comb-filter path using delayed feedback rather than a band-pass or resonant filter core.
No current warnings are attached to this effect.
