Music Visualizer: Turn music into live visuals, right in your browser

I built Music Visualizer to make listening to music feel more immersive—without requiring an upload, account, extension, or desktop app.

It turns live audio into 10 real-time visual styles directly in your browser. You can:

🎵 Start instantly with Demo Music
🖥️ Visualize supported system audio from Spotify, Apple Music, YouTube, and other players
🎤 Use your microphone for instruments, speakers, voice, or ambient sound
✨ Switch between 10 audio-reactive visual styles
⛶ Enter fullscreen for a distraction-free listening experience

Audio analysis happens locally on your device. Music Visualizer does not upload your audio or connect to your music-service account. Microphone and system-audio capture begin only after you grant permission.

One of the hardest parts was making browser audio sharing understandable. Different browsers and operating systems expose different capture options, so I added a step-by-step sharing guide and a built-in demo track that lets anyone test the visuals first.

I’d especially love your feedback on:

- Is the audio-source setup easy to understand?
- Which visual style do you enjoy most?
- What would make Music Visualizer a better listening companion?

Thanks for checking it out—I hope it gives your music a new visual dimension.
