Virtual Acoustic Reality
Virtual or augmented realities are often designed only visually and then underlaid with conventional stereo sound. In order to achieve an immersive experience of speech or musical events, however, the acoustics must also be produced and reproduced with the same care. This can be achieved with headphones (binaural synthesis) or with loudspeaker systems (sound field synthesis). We have the technical means and advise you in the planning and implementation of corresponding applications.
