Transform your internet connection into unique procedurally generated music. NETWAVE measures your real network performance and converts the speed test results into a live musical composition played directly in your browser.
Every test creates a one-of-a-kind track. A faster connection produces a different beat than a slower one — your music is a direct sonic fingerprint of your network.
- 🎼 Real-time Music Generation — Hear the beat build as the speed test runs
- 📊 Network-to-Sound Mapping — Ping, download, upload, and jitter control tempo, bass, melody, and rhythm
- 🔊 Web Audio Synthesis — Pure browser-based audio generation, no external files
- 💾 Export to WAV — Download your unique track as a high-quality audio file
- 🎨 Live Visualizer — Real-time frequency and waveform display during generation
- ⚡ Instant Playback — Replay your track or regenerate with a new speed test
For Developers & Engineers
- Debug network performance issues sonically
- Monitor connection quality in real-time
- Identify jitter and latency problems through audio feedback
For ISP Testing
- Audit broadband speeds across locations
- Create memorable reports with audio signatures
- Compare different network conditions
For General Users
- Entertainment — generate a unique track from your internet
- Share your connection speed as audio
- Visualize network performance in a creative way
For Educators
- Teach networking concepts through sound
- Make network latency tangible and audible
- Engage students with interactive demos
- Node.js 18+ and npm
- Python 3.9+ and pip
- Git
cd backend
python -m venv venv

pip install -r requirements.txtCreate a .env file in the backend/ directory (currently no required env vars, but can be added for api keys/config):
# Backend configuration (optional)# SPEEDTEST_API_KEY=your_key_here# DATABASE_URL=your_db_urlStart the server:
uvicorn main:app --reload --port 8000cd frontend
npm installCreate a .env.local file in the frontend/ directory:
# Backend API URL
NEXT_PUBLIC_API_URL=http://localhost:8000
# Optional: Analytics or service configurations# NEXT_PUBLIC_ANALYTICS_ID=your_idStart the development server:
npm run devNavigate to http://localhost:3000 in your browser.
Click RUN TEST & GENERATE MUSIC — the speed test runs automatically and generates your track in real-time.
Your network metrics are mapped to musical parameters:
| 📡 Metric | 🎵 Controls |
|---|---|
| Ping (ms) | Tempo — low ping = fast BPM, high ping = slow BPM |
| Download (Mbps) | Bass intensity — faster download = heavier bass |
| Upload (Mbps) | Melody brightness — faster upload = higher, brighter melody |
| Jitter (ms) | Timing variance — high jitter = loose, unpredictable rhythm |
Speed Test Progress:
- Ping measured → Drums start at the calculated BPM
- Download measured → Bass layer is added
- Upload measured → Melody layer is added
- Test complete → Full polished 8-bar loop plays from the beginning
Once the loop finishes, two options appear:
▶️ PLAY AGAIN — Replay the exact same beat without re-running the speed test- ⬇️ DOWNLOAD WAV — Export as a 44.1 kHz / 16-bit stereo WAV file (e.g.,
netwave-112bpm-125dl-45ul.wav)
- Frontend — Next.js 16 (App Router), TypeScript, Tailwind CSS, Web Audio API
- Backend — Python, FastAPI, speedtest-cli
- Visualizer — Canvas 2D with live frequency and waveform data
