nJam User Experiments : Enabling Remote Musical Interaction from Milliseconds to Seconds

Proceedings of the International Conference on New Interfaces for Musical Expression

Remote real-time musical interaction is a domain where endto-end latency is a well known problem. Today, the mainexplored approach aims to keep it below the musicians perception threshold. In this paper, we explore another approach, where end-to-end delays rise to several seconds, butcomputed in a controlled (and synchronized) way dependingon the structure of the musical pieces. Thanks to our fullydistributed prototype called nJam, we perform user experiments to show how this new kind of interactivity breaks theactual end-to-end latency bounds.
