Rythm.js is a JavaScript library that makes web page elements animate in sync with music or microphone audio using the Web Audio API. It maps CSS classes to frequency-based dance effects like scale, tilt, blur, and color changes.
Use cases
- make page elements pulse to music
- create audio-reactive visual effects on a website
- animate a landing page to a song's bass
- visualize microphone input in the browser
- add beat-synced animations to a music player page
When to choose
- you want fun audio-reactive animations with minimal setup
- you need CSS-class-driven effects synced to audio frequencies
- you want to support both audio files and microphone input
When to avoid
- you need serious audio analysis or spectrum visualization
- you need performance-critical canvas/WebGL visualizations
- your project requires a permissive license (GPL-3.0)
