How It Works
Technical view
The current vocal-family wet path is not a carrier/modulator analysis chain. It first builds a separately triggered synth phrase, then splits that phrase across three fixed band-pass formant bands where `motion` retunes the low and high bands and `color` retunes the middle band. `mix` crossfades the dry stereo preview source toward that formant layer, `blend` scales the wet contribution, and the result then passes through the shared DC-blocking, output-gain, and soft-limiting stage.

Signal Path
Compiled preview chain
Preview source: An internally generated picked-string phrase is widened to stereo with a 19-sample right-channel delay. The wet side is a separately synthesized carrier phrase filtered through fixed formant bands rather than a true live modulator/carrier analysis stage.

Effect core
Three-band formant-filtered synth layer crossfaded against the dry preview phrase.
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
- separately synthesized carrier phrase
- three moving band-pass formant bands
- dry / formant-layer crossfade
- 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: Crossfades the dry stereo preview source toward the current wet layer.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- color: Retunes the center frequency of the middle band-pass formant band.
- motion: Retunes the lower and upper band-pass formant bands.
- blend: Scales the level of the formant-filtered synth layer inside the wet path.

Controls
Audible controls in this DSP
Crossfades the dry stereo preview source toward the current wet layer.
Higher settings put more of the synthesized or resonant effect layer in front of the dry phrase.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the underlying effect structure.
Retunes the center frequency of the middle band-pass formant band.
Shifts the vocal focus toward a boxier or brighter vowel center.
Retunes the lower and upper band-pass formant bands.
Moves the vowel-like emphasis and articulation shape.
Scales the level of the formant-filtered synth layer inside the wet path.
Higher settings make the vocalized layer more pronounced.
Analysis
Code-derived notes
Current implementation shares the same three-band formant architecture with Talkbox-Style Formant. It does not analyze one signal as a modulator against another carrier yet.
