How it works: The Wario Synthesis Engine analyses MIDI files to identify melody, bass, and chord tracks. It then resynthesises each part using Web Audio oscillators tuned to mimic the Game Boy's 4-channel sound chip: two pulse wave channels, one wave channel, and one noise channel. All processing runs client-side in your browser - no server-side audio generation. Built with TypeScript, Vite, and Claude Code.
