Introduction

Due to the network latency, it is difficult to provide a system/software that allows musicians to play music together in Live accross an IP network. We estimate that musicians can play as in a room if latency is lesser than 20ms.
As it is not a technology limitation but a physical limitation (the light takes 66ms to travel to the oposite point of the earth), we provide a system where musicians can choose the latency not in seconds or milliseconds, but in number of beat according to a tempo in bpm (beat per minutes).

Additionnally, we have built a synchronization protocol to provide tempo shared among the remote sites.

Video

In these video, you can hear the ambient sound of the room. See the audio section to hear the sound comming from nJam, our prototype.
