How It Works
Technical view
The current `Convolution Plate` does not perform impulse-response convolution. It uses the shared diffuse reverb core and then shapes the wet tail with a mid peak EQ whose gain is tied to `space`. `decay` extends the shared core, and `tone` brightens that core as usual.

Effect core
Diffuse comb-and-diffuser reverb followed by post-verb mid peak 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
- four parallel damped comb stages
- two serial diffuser stages
- post-reverb high-shelf shaping
- post-reverb mid peak EQ
- dry / wet blend
- 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 between the dry source and the wet reverb field after the reverb core.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- space: Expands the base reverb dimensions and raises the gain of the post-reverb mid peak EQ.
- decay: Raises the feedback coefficients in the underlying diffuse reverb core.
- tone: Raises the damping cutoffs and final high-shelf brightness in the underlying core.
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 between the dry source and the wet reverb field after the reverb core.
Lower settings stay more direct; higher settings move the patch further into the ambient tail.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual reverb structure.
Expands the base reverb dimensions and raises the gain of the post-reverb mid peak EQ.
Moves the plate from more compact and neutral toward broader and more mid-forward.
Raises the feedback coefficients in the underlying diffuse reverb core.
Extends the sustain of the plate tail.
Raises the damping cutoffs and final high-shelf brightness in the underlying core.
Makes the plate darker at low settings and brighter at high settings.
Analysis
Code-derived notes
Current implementation is not performing impulse-response convolution; it uses the shared diffuse reverb core plus a post-verb mid peak EQ.
