a collaborative, network-enabled audio feedback instrument

GroupLoop is a browser-based, collaborative audio feedback control system for musical performance. Upon logging in, GroupLoop users send their microphone stream to other participants while simultaneously controlling the mix of other users' streams played through their speakers. Complex feedback loops involving several participants are possible by working together- in some cases, multiple feedback paths may overlap and interact. Users are able to shape the feedback sounds in real time by adjusting delay, EQ, and gain, as well as by manipulating the acoustics of their portion of the audio feedback path.

GroupLoop is capable of diverse and unexpected sounds, immeasurable reconfigurability, and in some cases, unrepeatable complexity. It creates new topologies for collaboration in performance, and invites thoughtful reflection on future topologies for real-time music collaboration over distance.

GroupLoop was published in NIME 2015, read the paper here.
