Party Mode is an audio visualizer experiment powered by d3.js and the web audio api. This is a work-in-progress and likely has lots of critical bugs! It requires a modern browser (preferably Chrome) and a decent CPU. This app was developed by Mathew Preziotte with lots of help and inspiration.

Try dragging an mp3 from your desktop into the browser, or press K for keyboard shortcuts.

For a list of known issues -- to help improve this experiment -- or to download and run this app locally, visit the Github page. Questions, comments and hugs can be directed here. Thanks for looking :) I had a lot of fun building this.
