looper - make music together online in a loop

Introduction

This project is about how people can make music together remotely. One big challenge here is latency, which makes it impossible to play in sync if latency is too high. The nice solution for this is to build a low-latency system, the approach followed e.g. on https://github.com/delude88/digitalstage. (See the nice explanations on http://digital-stage.org/?page_id=51, the ambition for the most advanced version is to have a end-to-end lateny of 30 ms.)

This project follows more a low-barrier approach: How can hobby musicians be enabled to play together and have fun, using their commodity hardware and just a browser? In this setup, ultra-low latencies cannot be achieved. The workaround chosen here is to play in a loop setting, similar to populer looper guitar effects pedals: This allows to hide latency up to the loop lenght.

Known limitations

Among many others: This is only tested with Firefox and Chrome.
