Resonator Reverb

Diffuse reverb tail with an added short resonant comb that imposes a pitched overtone on the ambience.

The current `Resonator Reverb` uses the shared diffuse reverb core and adds a very short comb branch whose delay is set directly in samples, creating a resonant overtone on top of the ambience. `space` changes both the main reverb dimensions and the resonator period, `decay` extends both the tail and the resonant ring, and `tone` brightens both sections.

Effect core

Diffuse reverb core plus a short resonator comb branch mixed into the wet tail.

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
  • added short resonator comb branch
  • 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 also increases the sample delay of the added short resonator comb.
  • decay: Raises the feedback of both the base diffuse reverb and the added resonator comb.
  • tone: Raises the damping cutoffs in both the base reverb core and the added resonator branch.

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

  • mix

    Active

    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.

  • output_gain_db

    Active

    Applies final post-effect level trim after DC blocking and before the output limiter.

    Matches loudness without changing the actual reverb structure.

  • space

    Active

    Expands the base reverb dimensions and also increases the sample delay of the added short resonator comb.

    Moves the resonant overtone from tighter, higher ringing toward a looser, lower resonance.

  • decay

    Active

    Raises the feedback of both the base diffuse reverb and the added resonator comb.

    Extends the ambience and lets the resonant ring persist longer.

  • tone

    Active

    Raises the damping cutoffs in both the base reverb core and the added resonator branch.

    Makes the reverb and the resonant overtone darker at low settings and brighter at high settings.

Analysis

Code-derived notes

Current implementation adds a very short comb resonator on top of the shared diffuse reverb core rather than using a separate bank of tuned resonators.
