JonssonicPlugins

A plugin development framework and collection of audio effects built with JonssonicDSP, JUCE, and CMake. Includes a lightweight framework for rapid plugin development with automatic parameter management and GUI generation.

Example Plugins

• Delay, Flanger, Reverb, EQ, Compressor, Distortion.

Framework

This project includes the jnsc::juce_interface - a lightweight framework that simplifies plugin development with JUCE by providing:

• ParameterManager: Type-safe parameter management with automatic APVTS integration and thread-safe updates
• ControlPanel: Automatic GUI generation from parameters with customizable layouts
• CustomLookAndFeel: Modern UI styling with knob graphics and consistent design (easily customizable by dropping your own knob PNGs in resources/knobs/)
• Parameter Types: Support for Float, Bool, and Choice parameters with built-in validation

The framework handles the boilerplate of parameter synchronization between GUI and audio threads, letting you focus on DSP implementation.

Creating a New Plugin

Use the provided Python script to quickly init a new plugin:

# Create a plugin in the plugins/ directory
python3 tools/init_new_plugin.py PluginName

# Create a demo plugin in the demos/ directory
python3 tools/init_new_plugin.py PluginName --demo

Examples:

# Create a Chorus effect plugin
python3 tools/init_new_plugin.py Chorus

# Create a demo showcasing oversampling
python3 tools/init_new_plugin.py OversamplingDemo --demo

The script will:

• Create a new directory with your plugin name
• Copy and customize all template files (CMakeLists.txt, source files, headers)
• Replace all "Template" references with your plugin name
• The plugin will be automatically detected and built by CMake

Next Steps After Creation:

1. Customize the parameters in YourPlugin/Params.h
2. Implement your DSP logic in YourPlugin/PluginProcessor.cpp
3. Modify the GUI in YourPlugin/PluginEditor.cpp
4. Build the plugin:

   # Configure CMake (if not already done)
   cmake --preset fetch-debug
   
   # Build the specific plugin
   cmake --build build/fetch-debug --target YourPluginName
   
   # Or build all plugins in the repo
   cmake --build build/fetch-debug
