IRT Shows BRS Technology at CeBIT 2012

This way the listener is able to “move acoustically” through the virtual room while the sound sources will be located at their fixed positions. Using BRS, someone is able to recreate the listening experience of a 5.1 loudspeaker setup in a real room via headphones. Within a close research cooperation with Sisvel Technology S.r.l, the BRS system will be on exhibition at the Sisvel booth - hall 15, booth A16.

The BRS system is the perfect tool for precise virtual loudspeaker reproduction. Regardless of the actual properties of an individual listening room, consumers can reproduce high-end audio quality without cost-intensive investments into sophisticated hi-fi equipment and room acoustics. Furthermore the BRS technology allows a flawless home theatre experience without spoiling the living room with bulky loudspeakers or disturbing the housemates with high playback levels. It is also ideally suited for enjoying video games in surround atmosphere and even portable enough to take the BRS system to friends and gaming conventions.

Controlled by headtracking data, the multichannel audio signals are convolved with measured or modelled binaural impulse responses of a high-quality monitoring room. This way, turning the head with headphones results in the same spatial perception as in the real room. The rendered headphone input signals offer accurate room-related localization of virtual loudspeakers, regardless of the head orientation.

During almost one decade of research IRT has led Binaural Room Synthesis technology to a maximum of audio quality within numerous development projects. Throughout the world the performance of IRT’s BRS solution is unrivalled.
