• Resumen

  • The Institute of Technical Acoustics (ITA) in Aachen has recently establis d its new Virtual Reality Lab, aimed for research and educational purpose. This laboratory is equipped with four potent computers for use on real-time room simulation and auralization, a stereoscopic projection system, an electromagnetic tracking device and eight high quality monitor loudspeakers array for immersive spatial audio reproduction. The hardware mentioned above allows the synthesis and reproduction of either binaural signals, by means of binaural synthesis and dynamic crosstalk cancellation technique, or stereophonic signals, using the approaches of vector-base amplitude panning (VBAP) and higher order ambisonics (HOA). In this paper we will outline the above mentioned methods and describe how they are integrated with the virtual reality system under development in ITA.
