How It Works
Technical view
The current wobble filter drives left and right resonant low-pass centers from two slow offset LFOs and mixes those filtered branches back with the dry source. `depth` widens the sweep range, `rate` controls the motion speed, and `tone` raises the filter resonance, so `Mod Filter` is presently the same code path as `Stereo Wobble`.

Signal Path
Compiled preview chain
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 modulation core.

Preview source

Effect core
Stereo resonant low-pass wobble with independently modulated filter centers.
Signal path
The static waveform and the live player both reflect this compiled signal chain.
- internal picked-string demo phrase
- stereo spread with a short right-channel delay
- dual modulated resonant low-pass filters
- dry / wet mix
- DC blocker
- output gain trim
- final tanh limiter
Controls that matter
These are the currently active controls detected in the FAUST source for this effect.
- mix: Blends the untouched stereo preview source with the processed path after the modulation core.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- depth: Widens the sweep range of the left and right resonant low-pass centers.
- rate: Sets the speeds of the slow offset LFOs that move the filter centers.
- tone: Raises the resonance of the low-pass filters.

Controls
Audible controls in this DSP
Blends the untouched stereo preview source with the processed path after the modulation core.
Lower settings keep more direct attack and body; higher settings push the effected motion further forward.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual modulation or filtering structure.
Widens the sweep range of the left and right resonant low-pass centers.
Makes the wobble travel farther and sound more exaggerated.
Sets the speeds of the slow offset LFOs that move the filter centers.
Changes how quickly the wobble evolves.
Raises the resonance of the low-pass filters.
Makes the sweep rounder and more vocal as it increases.
Analysis
Code-derived notes
Current implementation shares the same resonant low-pass wobble core between Stereo Wobble and Mod Filter.
