This workshop will show how to install and use a remote collaboration device {\em ovbox} \cite{ovbox} built upon the tool `zita-njbridge' and the Toolbox for Acoustic Scene Creation And Rendering (TASCAR). The ovbox is a remote collaboration box developed by the ensemble ORLANDOviols primarily to allow rehearsals during the lockdown due to Covid19 pandemia. This box is completely built upon open source software and open or standardized hardware. At the University of Oldenburg this project was extended towards application for low-delay real-time streaming in hearing experiments, e.g., to render complex virtual acoustic environments on a powerful PC in the lab, and stream the signals to the user via a device with calibrated reproduction hardware. Also low-delay transmission of head movements for head-tracked rendering is possible.

During the workshop we will explore some technical details of the system, and how to install it on your system. We will explain the applied 3D virtual acoustic rendering. At the end of the day you will be able to jam together with other participants of the LAC.
