Music Visualization with Three.js

I’ve been experimenting with music visualization using Three.js and one of my unreleased tracks. It’s basically my love for music + web dev mashed together , creating visuals that dance to the beat in real-time.

🔗 Live Demo

The visuals respond to the audio frequency , move your mouse, change the song, enjoy the chaos!

🛠 Tech Stack

Three.js → 3D graphics & WebGL
Web Audio API → real-time audio analysis
Vanilla JS → keeping it simple

Key features:

Particle systems reacting to bass, mids, highs
Color palettes that shift with music energy
Smooth animations synchronized to beats

💡 How I Built It

Audio Analysis → grab frequency data with Web Audio API
3D Scene → particles in Three.js respond to frequencies
Animation Loop → update visuals every frame to match audio

🎨 Creative Decisions

Cool colors for calm sections, warm colors for intense parts
Momentum-based particle motion for natural flow
Less = more , simple effects often look better than over-the-top chaos

⚡ Challenges

Performance → solved with instanced particles, optimized shaders, adaptive quality
Audio sync → low-latency audio + multiple frequency bands
Cross-browser issues → feature detection & fallbacks

✨ What I Learned

Smooth visuals > flashy but laggy
Frequency analysis reveals hidden patterns in music
Colors and motion dramatically affect mood
Interactive elements make people feel connected

🔮 Future Fun

VR/AR support for full immersion
Multi-track visualization for complex songs
User-customizable colors & effects
Export features & social sharing

This project is my playground where code meets creativity. Music visualization isn’t just pretty lights , it’s about translating audio into emotion, finding patterns, and creating interactive experiences.

Code is on GitHub , tweak it, remix it, make your own musical visual world.
