How It Works
Technical view
The current gate measures signal level with a low-passed absolute-value follower, subtracts an effective threshold, multiplies the result, and clamps it into a 0-to-1 control signal that gates the audio. `squeeze` acts as the threshold side of that equation through the internal `shape` alias, while `contour` increases the gate steepness rather than boosting lows.

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.

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
- smoothed envelope follower
- clamp-style gate / expansion stage
- 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: Aliases into the internal threshold term used by the clamp gate.
- tone: Adjusts the post-gate high shelf.
- contour: Raises the multiplier that steepens the clamp gate response.

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.
Aliases into the internal threshold term used by the clamp gate.
Higher settings effectively lower the gate threshold so more signal passes before the clamp shuts down.
Adjusts the post-gate high shelf.
Changes how bright the gated output feels once the signal is open.
Raises the multiplier that steepens the clamp gate response.
Makes the gate clamp harder and switch more abruptly between open and closed states.
Analysis
Code-derived notes
Current implementation shares the same clamp-style gate core as Intelligent Noise Suppressor, Downward Expander, and Resonance Suppressor.
