Fraunhofer Institute for Integrated Circuits IIS introduces its novel Spatial Audio Coding technology, which enables 5.1 Surround Sound for Digital Audio Broadcasting DAB. The Bayerische Rundfunk (BR) and Bayern Digital Radio (BDR) broadcast the first 5.1 program over DAB live on "Bayern 4 Klassik" during the Medientage event in Munich. A DAB surround receiver prototype was developed and integrated in a passenger car by the Panasonic Automotive Systems Europe GmbH.
Spatial Audio Coding SAC is a new technology developed by Fraunhofer IIS in collaboration with Agere Systems. This generic surround extension can be associated with almost any perceptual audio codec while remaining fully backward compatible to stereo or even mono broadcasting. The achieved audio quality is very close to a fully discrete surround system despite the fact that the surround image is represented by only 16kbit/s of additional data. The DAB implementation is based on a combination of the MPEG Layer-2 codec with the surround information embedded as ancillary data into the bitstream. A conventional DAB receiver will simply ignore the surround information whereas DAB surround receivers reproduce the full multi-channel sound. On the part of the broadcasting station, the SAC based system only requires an SAC compatible audio encoder.
During the Medientage event in Munich, the first live broadcast of 5.1 surround sound over DAB is presented at the Bayern Digital Radio GmbH booth Y1 as well as the Panasonic Automotive Systems Europe booth Y2. The transmission of the Program Associated Data PAD is still possible while using Spatial Audio Coding technology.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
