How It Works
Technical view
The current `Freeze Reverb` implementation does not use the shared diffuse reverb core for its wet path. Instead, it builds the effect from one long damped comb loop with relatively high feedback and a post-loop high shelf. `space` sets the loop length, `decay` raises the loop feedback, and `tone` brightens the frozen texture.

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 reverb core.

Effect core
Long damped comb loop with post-loop high-shelf 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
- long damped comb loop
- post-loop high-shelf shaping
- 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: Sets the delay length of the long comb loop used for the frozen reverb texture.
- decay: Raises the feedback coefficient of the long comb loop.
- tone: Raises the damping cutoff inside the loop and brightens the post-loop high shelf.

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.
Sets the delay length of the long comb loop used for the frozen reverb texture.
Moves the frozen ambience from a tighter resonance toward a longer suspended wash.
Raises the feedback coefficient of the long comb loop.
Makes the frozen tail sustain longer and feel closer to a held ambience.
Raises the damping cutoff inside the loop and brightens the post-loop high shelf.
Makes the frozen texture darker at low settings and brighter at high settings.
Analysis
Code-derived notes
Current implementation uses a single long comb loop for the wet path rather than freezing the shared diffuse reverb core.
