Granular Verb Delay

A granular delay and reverb plugin built with JUCE framework for Ableton Live and other DAWs.

Features

• Granular Delay Engine: Create textured, granular delay effects with up to 64 simultaneous grains
• Reverb Processing: Lush reverb with granular characteristics
• Stereo Width Control: Adjust the stereo field from mono to ultra-wide (0-200%)
• Visual Feedback: Real-time waveform and grain position visualization
• 8 Creative Parameters: Full control over grain size, density, pitch, and more
• Multiple Formats: VST3, AU (macOS), and Standalone

Quick Start

macOS (Recommended - No Security Warnings!)

# Easy one-line build
./build_macos.sh

# Or for universal binary (Intel + Apple Silicon)
./build_macos.sh --universal

See BUILD_MACOS.md for complete macOS build instructions including:

• How to avoid macOS Sequoia security warnings
• Code signing for distribution
• Troubleshooting Gatekeeper issues

Linux

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build . -j4

Windows

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build . --config Release

Plugin Parameters

• Delay Time: Length of the delay (10ms - 2 seconds)
• Grain Size: Size of individual grains (10ms - 500ms)
• Grain Density: Number of grains spawned per second (1-100)
• Grain Pitch: Pitch shift for grains (0.5x - 2.0x)
• Reverb Mix: Amount of reverb in the signal (0-100%)
• Stereo Width: Stereo field width (0-200%)
• Feedback: Delay regeneration amount (0-95%)
• Dry/Wet Mix: Balance between processed and original signal (0-100%)

Installation

macOS

# AU Plugin (for Logic, GarageBand, Ableton, etc.)
cp -r "build-macos/.../Granular Verb Delay.component" ~/Library/Audio/Plug-Ins/Components/

# VST3 Plugin (for most DAWs)
cp -r "build-macos/.../Granular Verb Delay.vst3" ~/Library/Audio/Plug-Ins/VST3/

# Standalone App
cp -r "build-macos/.../Granular Verb Delay.app" /Applications/

Then rescan plugins in your DAW.

Linux

# VST3 Plugin
cp -r build/GranularVerbDelay_artefacts/Release/VST3/*.vst3 ~/.vst3/

# Standalone
cp build/GranularVerbDelay_artefacts/Release/Standalone/Granular\ Verb\ Delay ~/bin/

Windows

# VST3 Plugin
copy build\GranularVerbDelay_artefacts\Release\VST3\*.vst3 "C:\Program Files\Common Files\VST3\"
