How It Works
Technical view
Despite the name, the current left/right offset patch is not an LFO modulation engine. It crossfades each channel toward a separate short static delay, with `motion` setting the left delay time, `width` setting the right delay time, and `mix` controlling the wet contribution. The declared `tone` control is inactive, 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 the shared 19-sample right-channel offset before each side gets its own separate static short-delay offset.

Preview source
An internally generated picked-string phrase is widened to stereo with the shared 19-sample right-channel offset before each side gets its own separate static short-delay offset.
Effect core
Separate left and right short-delay offsets 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
- left short-delay offset
- right short-delay offset
- per-channel dry / delay 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: Sets the right-channel short-delay time.
- motion: Sets the left-channel short-delay time.
- tone: Declared in the shared control set but unused in the current preview code.

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.
Sets the right-channel short-delay time.
Higher settings move the right-side offset farther away from the dry signal.
Sets the left-channel short-delay time.
Higher settings move the left-side offset farther away from the dry signal.
Declared in the shared control set but unused in the current preview code.
Changing it currently has no effect on the sound.
Analysis
Code-derived notes
Current implementation uses static short delays with different left and right times. There is no oscillator-based modulation yet, and the declared tone control is inactive.
