A music visualization playground built with Javascript, HTML5 Audio, and Canvas. I made it so I could experiment with music visualization without continuously recompiling the code, reloading the page, or restarting the music.

Try it Here!

1. Drag & Drop some audio files (mp3, ogg, or whatever) into the playlist on the Music tab.
2. Click on a song in the playlist to start the music.
3. Go to the Code tab and switch between visualization scripts using the dropdown ("Examples/Bars" is selected by default).
4. If you edit a script or create a new one, your changes will take effect when you click Save.
5. Read the Docs tab for more information.

• Scripts are saved to your browser's LocalStorage. If you make something you want to keep, export it so it doesn't get lost.
• This code was originally written in 2014. I have not made any major changes since then.
• I have no real experience with audio analysis algorithms. The provided examples and utilities scripts are rather naive. My beat counter in particular is pretty bad.
