Abstract

In this paper we describe a two-way audio communication system using arrays of microphones and loudspeakers to create a virtual acoustic window. We compare three different methods for capturing the sound: wave field sampling using a line array of microphones, an adaptive beamformer, and close-talk microphones. For sound reproduction, we employ wave field synthesis. In the paper we review the acoustic and perceptual requirements for a real-time virtual acoustic window system, and report results of a set of listening experiments performed with the system.
