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)
