Cave Reverb

A massive algorithmic reverb plugin with quad-tank architecture and octave shimmer, built with JUCE.

Features

Reverb Engine

• Quad-Tank Design - Four cross-feeding delay tanks based on the Dattorro/Griesinger topology
• 8-Stage Input Diffusion - Dense diffusion network with prime-number delays for smooth smearing
• Octave Shimmer - Pitch-shifted (+12 semitones) signal blended into the feedback path
• Modulated Tanks - LFO bank (0.3–0.6 Hz) for evolving, organic texture

Main Controls

• Size - Room size scaling all tank delays (small room to massive hall)
• Decay - Reverb tail length from tight to near-infinite
• Damping - High-frequency absorption simulating air and surface absorption
• Mix - Dry/wet balance
• Shimmer - Octave-up shimmer intensity in the reverb tail

Advanced Controls

• Diffusion - Input diffusion amount for smearing early reflections
• Pre-Delay - Gap before reverb onset (0–500ms)
• Width - Stereo spread using M/S processing
• Modulation - Internal tank modulation depth
• Freeze - Infinite hold for sustained pads and drones
