In this study, a sound ?eld renderer which can create the virtual sound ?eld by input of the real-world sound is developed. The system consists of 24 channels loudspeaker array, 4 channels microphones, and a real-time convolver. The audio signals received at microphones are convoluted in real time with the impulse responses calculated by the sound ?eld rendering. The rendering model of Yamaha hall in Tokyo is made. The calculated reverberation curve and the measured one show good agreement. The delay time of the system was evaluated as 7.8 ms, which may not affect the perception. It is shown that the renderer is possible to produce the virtual sound ?eld in high presence.
