Music-js is a music visualization program that includes many built-in customization options for a playlist of music. Provided links to MP3, Ogg Vorbis, and/or WebM sound files, it can create a real-time visualization of the music as it plays, using the HTML5 Audio API.

This application supports visualization of external sound files, enabling this to easily become a plugin for other sites.

Documentation will be added in another update. For now, refer to the JSON object in index.html under /static for a demonstration of customizable attributes.

To install this server, run

git clone https://github.com/patrickroberts/music-js.git
cd music-js/static/
mkdir media

At this point you should add songs to the media directory and edit the JSON in index.html to include the songs you want to visualize. After that, return to the terminal or command prompt and run

cd ..
npm install
node app.js

then open http://localhost:8080.
