We were invited to realize the spatial sound design and mixing for an immersive media installation created by m box Berlin at the German Ivory Museum in Erbach Castle in the Odenwald. The museum brings ivory art back to its place of origin, where Count Franz I von Erbach (1754-1823) popularized ivory carving in the late 18th century. The “Blackbox” exhibit transforms a 60 m² room into an intense experience. Visitors enter a darkened room through an airlock, which appears fragmented and challenging to grasp, thanks to countless mirrors. Graphic, abstract animations on five portrait-format display steles and LED strips are the only light sources and create a fascinating visual landscape. The concept of “Blackbox” breaks with traditional forms of historical presentations. It places the life and work of Count Franz I in a larger thematic and temporal context, provoking connections to current social phenomena through fictitious diary entries by the Count. The fragmented visual aesthetics and the superimposed, programmatic sound installation complement each other, creating a multi-layered associative level that invites visitors to re-contextualize the information from different perspectives. We conducted the 3D mixing using our spatial production software, MNTN. As part of the overall auditory concept, we also handled the technical planning and installation of the 20.2-channel sound system to translate the auditory concept into an adequate listening experience. Michael Peter (m box) created the music and audio content.
