The collaboration with ARRI Media comes about through personal contacts made in the course of mixing the 3D sound together with Tom Ammermann of New Audio Technology. "We recommended to Kraftwerk that they have a cinema version of `3-D The Catalogue` made. They loved the idea," recalls Daniel Vogl, site manager of ARRI@Bavaria Film and Head of the Sound Department at ARRI Media, the ARRI division responsible for post-production. And that was how the idea was born to hold exclusive cinema screenings in six German cities a few days before the release of "3-D The Catalogue." And rather than simply taking the Blu-ray material and projecting it onto the big screen, Kraftwerk stayed true to its principle of insisting on the best quality available. That meant a special cinema mix in Dolby Atmos – a scalable sound system with which sound objects can be positioned in a space. The mix was produced in Studio A at ARRI@Bavaria Film in Geiselgasteig near Munich – the same rooms in which the industrial production of talkies began in Germany in 1930. It is in this historical location that Kraftwerk's sound engineer Fritz Hilpert, Tom Ammermann, and ARRI Media's Head Sound Engineer Tschangis Chahrokh, together with his team, created the soundtrack in Dolby Atmos under cinema-acoustic conditions. And the result is something special: the re-interpretations of "Radioactivity," "Trans Europe Express," and "The Robots" are groundbreaking in the field of 3D audio.
