The SPRAWL system is an audio and information routing network,
enabling enhanced ways of interaction for musical ensembles. A
Linux audio server with a SuperCollider mixing and spatialization
system is connected to several access points via ethernet, using Jack-
Trip for audio transmission. The unified access points are based on
a Raspberry Pi 4 with a 7 inch touch screen and a USB audio in-
terface, running SuperCollider, Puredata and additional tools. Using
custom applications on these units, musicians are able to control the
routing and spatialization of the system, allowing personal monitor-
ing, the distribution of click tracks and related auditory information,
as well as visual information and cues. The system is designed as
a meta-instrument for developing individual configurations and soft-
ware components for specific compositions and use cases. It has
been successfully used in on-site concerts and ported to wide area
networks for remote rehearsals and performances.
