After using Portal 2's in-game level editor for a while I really started to like the background track. In this web app, I wanted to bring these sounds to the web.
I used the original blips and background sounds from Portal 2, so this web app will sound mostly identical.
If you have questions or ideas, please contact me on Twitter.
Volume: 80 %
Blip delay: 2-12 sec.
Background vol: 40 %
