Spectrum Analyzer Demo

See it here: http://three-spectrum.herokuapp.com

This is a spectrum analyzer demo that I did for fun using the HTML5 Web Audio API, dsp.js and three.js.

It's a variation on another demo I did using d3.js: https://github.com/arirusso/d3-audio-spectrum

Local Installation

There is a config.ru file included so that you can serve the project locally using Rack

  • Make sure rack is installed
  • Clone the git repo

git clone git@github.com:arirusso/d3-audio-spectrum.git

cd d3-audio-spectrum

rackup config.ru

A frequency sweep mp3 is included for demo purposes but any audio file can be used.
