The OVBOX system is a system for low-delay network audio communication [1]. It features individual 3D virtual acoustics based on TASCAR [2], integration of head tracking for dynamic binaural rendering as well as rendering of distributed moving sound sources. The system can be used for remote rehearsals as well as networked music performances. It has been used by the ORLANDOviols ensemble for a series of streaming concerts [3], but also for academic research [4,5,6,7,8].
The system consists of several components: the client device, which is this software (optionally running on a dedicated computer, see installation instructions), a configuration server with a web interface for the users and a REST API, and a list of room servers, which handle the session.
The source code of the configuration server can be found here. The source code of the room server can be found here.
Installation instructions can be found on the wiki pages. A user manual for the ORLANDOviols configuration server can also be found on the wiki.
The client software can run on Raspberry Pi (models 4B and 3B+), Ubuntu Linux and on MacOS. See installation instructions for details. A desktop client for Windows is currently under development.
