Official effect
Three-band formant bank with an LFO-driven vowel position for moving voice-like color.
The current patch builds a vowel-like spectrum by summing three band-pass stages whose centers move together from a shared `vowelPos` LFO. `focus` and `motion` reshape the lower and middle bands, while `rate` sets morph speed, so the result behaves like a continuously moving formant bank rather than speech analysis or articulation tracking.
Static peaks come from the compiled FAUST preview render. The live scope is drawn from the browser playback output in real time.

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.

Three-band formant bank with shared LFO-driven vowel-position modulation.
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.
Adjusts the lower formant band placement and bandwidth of the first band-pass stage.
Changes the weight and mouth-like emphasis of the lower vowel region.
Adjusts the width of the middle formant band while contributing to the overall vowel contrast.
Changes how hollow or nasal the moving vowel shape feels.
Sets the speed of the internal vowel-position LFO that sweeps the band-pass centers.
Changes how quickly the filter morphs between vowel-like positions.
Analysis
Current implementation shares the same three-band moving formant core across Formant Filter, Talking Filter, and Vowel Morpher.
No current warnings are attached to this effect.
