This is a spectrum analyzer demo that I did for fun using the HTML5 Web Audio API, dsp.js and d3.js.
There is a config.ru file included so that you can serve the project locally using Rack assuming you have Ruby installed
git clone git@github.com:arirusso/d3-audio-spectrum.git
cd d3-audio-spectrum
bundle install
rackup config.ru
- Open http://localhost:9292 in your browser
A frequency sweep mp3 is included for demo purposes but any audio file can be used.
