The Technische Universität Berlin will offer an ear candy on tuesday, 29th august, in Hörsaal H 104 at 19:30.
There will be a life broadcast of an organ concert transmitted from the Kölner Dom to the TU Berlin.
The audience (650 seats) will hear a holographic reproduction from about 2700 speakers (yes, two thousand ..) which are on a band around the listeners in ear height with some extra speakers in the front and at the ceiling.
The applied technique is the wave field synthesis (WFS) which performes a synthesis of wave fronts out of loudspeaker arrays. The localization of virtual sources in WFS does not depend on or change with the listener's position. The speakers will be fed by digital lines from 832 independent sources, which are generated in a cluster consisting of 16 computers. The transmission from Köln to Berlin is provided by a broadband internet connection.
The organizer announced that this technique offers not only an authentic reproduction of the Kölner Doms acoustics but also the real perception of depth for the different organs within the Kölner Dom.
