I’ve been experimenting with generative music systems in the browser, and I wanted to share a project I recently finished.
This is an infinite ambient music generator built using pure HTML & JavaScript, running entirely in the browser via the Web Audio API.
No backend, no frameworks — just algorithms and sound design.
🎼 What does it do?
The engine continuously generates soft ambient music using:
- Markov-style note transitions
- Dual classical guitar layers
- Piano & ambient background textures
- Bass and subtle rhythmic elements
- Emotion-based dynamics & tempo modulation
Each session is never repeated — the music evolves endlessly.
🔊 Sound Design Highlights
- Algorithmic arpeggios & melodic fragments
- Paulstretch-style ambient layers
- Real-time EQ, filter & reverb control
- FFT spectrum visualization for live feedback
- Smooth transitions designed for long listening sessions
Perfect for:
- studying
- coding
- meditation
- background focus
🛠️ Tech Stack
- HTML
- Vanilla JavaScript
- Web Audio API
- Tone.js
- Algorithmic composition logic (Markov-inspired)
▶️ Live Demo on YouTube
I’m running this engine as a 24/7 live stream here:

💡 Why I built this
I wanted to explore how far browser-based audio can go without plugins or native apps.
This project shows that modern JavaScript is powerful enough to create immersive, evolving music systems in real time.
If you’re interested in:
- creative coding

I’d love to hear your thoughts.
Thanks for listening 🎧
