How It Works
Technical view
The current acoustic-body path is a fixed EQ contour rather than a resonant body model. It adds a low shelf, a broad 820 Hz peak, and a tone-controlled high shelf to each channel, then crossfades that contour with the dry stereo preview source through `mix`. `width` sets the low-shelf gain, `motion` drives the 820 Hz peak amount, and `tone` opens the upper shelf before the shared DC-blocking, output-gain, and soft-limiting stage.

- delay processing
- oscillator / LFO modulation
- DC blocking
Signal Path
Compiled preview chain
Preview source: An internally generated picked-string phrase is widened to stereo with the shared 19-sample right-channel offset before it is shaped by the body-style EQ contour.

Preview source
An internally generated picked-string phrase is widened to stereo with the shared 19-sample right-channel offset before it is shaped by the body-style EQ contour.
Effect core
Three-stage shelf and peak EQ contour 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
- shared stereo spread with a short right-channel delay
- low-shelf reinforcement
- 820 Hz peak contour
- high-shelf trim
- dry / EQ 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 or scales the current wet layer against the dry stereo preview source.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- width: Raises the low-shelf boost in the body-style EQ contour.
- motion: Raises the broad 820 Hz peak in the contour stage.
- tone: Sets the final high-shelf trim.

Controls
Audible controls in this DSP
Crossfades or scales the current wet layer against the dry stereo preview source.
Higher settings make the processed layer more dominant relative to 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.
Raises the low-shelf boost in the body-style EQ contour.
Higher settings add more body and low-mid weight.
Raises the broad 820 Hz peak in the contour stage.
Higher settings emphasize the middle resonance region more strongly.
Sets the final high-shelf trim.
Higher settings make the contour brighter and more open.
Analysis
Code-derived notes
Current implementation is an EQ contour rather than a more resonant physical body model.
