This is the (old, made 2.5 years ago) application I implemented for my BSc thesis called "WebLooper".

It aims at simulating a loop station like the one often used by DUB FX (BOSS RC-50, here is an example of it: https://www.youtube.com/watch?v=WhBoR_tgXCI ). But do not expect even 5% of its features. :D Although you can create "online peer-to-peer concerts" (based on WebRTC). I've only tested it on Chrome but I'll try to work on it to make it compatible with at least Firefox.

I was looking at some of my old projects and then, since the source code of this one was already on GitHub, I decided to put it online to let others try it. It has some ugly bugs and the code was written on a serious rush but, hey, maybe someone might have fun with it and, maybe, improve the code him/herself or give me some (constructive) feedback?
