For real-time transmission of a sound field in a large area, it is necessary to transform received signals of a microphone array into driving signals of a loudspeaker array to reproduce the sound field. We previously proposed a signal transform method for planar or linear arrays of microphones and loudspeakers that uses an analytically derived filter, called the wave field reconstruction filter (WFR filter). By using the WFR filter for linear arrays with 64 channels, we developed a prototype real-time sound field transmission system over an IP network. The results of the subjective listening tests indicated that the source localization accuracy for virtual sound sources is comparable to that for real sound sources in a large listening area.
