How to Create VST3 Plugins with AI – Audio Plugin Coder (APC) Open Source

Stop Dreaming, Start Shipping: Build Professional VST Plugins Using Natural Language

You have a world-class idea for a synth or effect, but C++ feels like a brick wall?

The days of spending years mastering DSP (Digital Signal Processing) before hearing your first sound are over. Introducing Audio Plugin Coder (APC) – the first open-source framework that lets you “vibe-code” professional audio plugins using the power of AI Agents like Claude Code, Cursor, and Kilo.

Why APC is a Game Changer for Audio Developers

Traditional plugin development is broken. Between JUCE boilerplate, CMake configurations, and debugging real-time audio crashes, 90% of creative ideas die in the “setup phase.” APC changes the workflow from programming to conversing.

     
• ✅ No C++ Expertise Required: Describe your DSP ideas in plain English. APC and your AI Agent handle the heavy lifting.

     

• ✅ Industry Standard: Built on JUCE 8, ensuring your plugins work in Every DAW (Ableton, FL Studio, Logic, etc.).

     

• ✅ Agent-Agnostic: Whether you use Claude, Kilo, or Antigravity – APC provides the structure they need to succeed.

     

• ✅ One-Click Packaging: Automatically generate installers for Windows, macOS, and Linux.

From Prompt to Plugin: The 5-Minute Workflow

APC uses a unique 5-Phase System that tracks your progress. You can stop, switch AI models, and resume exactly where you left off.

1. DREAM: Define your concept (e.g., “A warm vintage tape delay with wow/flutter”).
2. PLAN: The AI designs the DSP architecture and chooses your UI path (C++ or HTML5).
3. DESIGN: Generate visual mockups and GUI components without touching a pixel.
4. IMPLEMENT: The AI writes the core logic, parameter bindings, and signal chain.
5. SHIP: Hit one command to build professional, distribution-ready installers.

“I’ve spent 18 months yelling at LLMs so you don’t have to. APC is the result of thousands of hours of trial and error, distilled into a framework that actually works for real-world audio tools.”
