I vibe-coded a complete React rewrite of my multi-track audio editor with Claude.

  Waveform Playlist v5 started as a "let's see how far AI can take this" experiment. The original was vanilla JS (~8 years
  old). The new version is React + Tone.js with proper TypeScript, tree-shaking, and a modular package structure.

  What we built: canvas waveforms, drag-and-drop clip editing, 20+ Tone.js effects, AudioWorklet recording, WAV export,
  annotations, theming.

  Still in alpha, but functional. I'd estimate 80%+ of the code was AI-generated.
