Bloom Reverb

Diffuse reverb with a delayed second feed that blooms into a later swell.

The current bloom family uses the shared diffuse reverb core, then adds a delayed feed that re-enters the same core to create a second swell behind the first tail. `space` changes both the base dimensions and the timing of that delayed re-entry, `decay` shapes the persistence of the shared core, and `tone` brightens the resulting bloom.

Effect core

Diffuse reverb with a delayed feed that re-enters the same core for a second swell.

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
  • delayed re-entry into the same reverb core
  • 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 lengthens the added delayed send that re-enters the same reverb core.
  • decay: Raises the feedback coefficients inside the underlying diffuse reverb core.
  • tone: Raises the damping cutoffs and high-shelf brightness inside the shared reverb 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

  • 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 lengthens the added delayed send that re-enters the same reverb core.

    Moves the bloom from a tighter swell toward a later, wider secondary wash.

  • decay

    Active

    Raises the feedback coefficients inside the underlying diffuse reverb core.

    Extends the base tail that both the direct and delayed feeds excite.

  • tone

    Active

    Raises the damping cutoffs and high-shelf brightness inside the shared reverb core.

    Makes the blooming tail darker at low settings and brighter at high settings.

Analysis

Code-derived notes

Current implementation shares the same delayed-reentry bloom core across Bloom Reverb and Particle Reverb.
