🎵 CrowdTune Cloud Coordinator

✓ Service Running

Architecture

• Cloudflare Workers + Durable Objects (session coordination)
• R2 Storage (audio files)
• WebSocket (real-time desktop notifications)
• 100% Reliable (works through any firewall/NAT)

API Endpoints

• POST /api/sessions - Create session
• POST /api/sessions/:id/upload - Upload audio (idempotent)
• GET /api/sessions/:id/ws - WebSocket notifications
• GET /api/sessions/:id/files - List files (polling fallback)
• GET /api/sessions/:id/download-wav - Download test WAV

📱 iOS App: Scans QR code → uploads via HTTPS (exponential backoff retry)

💻 Desktop App: WebSocket listener → downloads from R2 → processes audio

Deployed on Cloudflare's global network • Free tier: 100K requests/day
