In this report, a realtime sound field renderer which can interactively produce the virtual sound field is developed. The developed renderer consists of a realtime convolver, 24 channels loudspeaker array and 4 channels microphones. The convolver can convolve the input signals from microphones with the impulse responses calculated by the sound field renderering in realtime. In the system, the input and output signals are transferred through the 1 Gbit/s audio network system (Dante). The performances of the renderer are evaluated. The delay time of the system was evaluated as 7.8ms, which may not affect the perception. The ratio of the amplitude of the direct and the reflected wave, and the reverberation curves were then evaluated for the renderer. It is found that the renderer is possible to produce the virtual sound field interactively. |
