How It Works
Technical view
This patch uses the same current signal path as Studio Compressor and Optical Compressor: a low-passed envelope controls a gain-scaling stage, then low- and high-shelf shaping finish the result. It already produces assertive leveling, but it is not yet a distinct FET-style attack/release or coloration model.

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 dynamics or EQ core.

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 dynamics or EQ core.
Effect core
Envelope-dependent gain reduction with post-compression low-shelf contouring and high-shelf tone shaping.
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
- envelope-following gain reduction
- low-shelf contour shaping
- post-processing high-shelf tone shaping
- 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 core effect.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- squeeze: Raises the multiplier applied to the smoothed input envelope in the denominator of the gain-scaling stage.
- tone: Adjusts the post-processing high shelf.
- contour: Raises the numerator of the gain-scaling stage and adjusts the post-processing low shelf.
Code-backed analysis
The generated description is tied to the active helper blocks and routing found in the current DSP.

Controls
Audible controls in this DSP
Blends the untouched stereo preview source with the processed path after the core effect.
Lower settings keep more dry attack and natural dynamics; higher settings push the processed behavior forward.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual dynamic or EQ structure.
Raises the multiplier applied to the smoothed input envelope in the denominator of the gain-scaling stage.
Adds firmer peak control and denser sustain.
Adjusts the post-processing high shelf.
Sets how bright or controlled the leveled top end feels.
Raises the numerator of the gain-scaling stage and adjusts the post-processing low shelf.
Shifts the leveled signal toward leaner or fuller body.
Analysis
Code-derived notes
Current implementation shares the same envelope-leveling compressor core as Studio Compressor, Optical Compressor, Sustain Compressor, Parallel Compressor, Multi-Band Compressor, and Upward Compressor.
