Beyond Basic BPM Detection

The realtime-bpm-analyzer library works well today using amplitude thresholding, but it's just the beginning. We envision a comprehensive ecosystem of tools that will transform how musicians, DJs, and audio enthusiasts interact with music tempo.

What We've Built

  • ✓Open-source realtime-bpm-analyzer library
  • ✓Real-time audio analysis in browser
  • ✓Multiple input sources (files, streams, mic)
  • ✓Free demo web application

What We Want to Build

  • →Browser extension for BPM detection everywhere
  • →AI/ML models beyond amplitude thresholding
  • →YouTube integration for harmonic playlists
  • →Collaborative BPM database

The Challenge

Advanced algorithms, AI models, and browser extensions require significant time, energy, and resources. Current amplitude thresholding works, but it's limited. We need your support to build more sophisticated solutions.
