SPATIAL AUDIO SIGNAL REPRODUCING DEVICE AND SPATIAL AUDIO SIGNAL REPRODUCING METHOD

摘要

A spatial audio signal reproducing device for generating a loudspeaker sound to giving the listener a natural sense of presence compared with conventional reproducing methods. The spatial audio signal reproducing device (1) comprises reproduction space information acquiring means (4) for acquiring reproduction space information (11) on a preproduction space (23), transfer function generating means (6) for generating, from the reproduction space information (11), a transfer function (13) whose input is the input signal (14) inputted into a loudspeaker (8) and whose output is a reproduction space audio signal in a predetermined position of the reproduction space (23), and loudspeaker input signal generating means (7) for generating the input signal (14) inputted into the loudspeaker (8) in such a way that the difference between the reproduction space audio signal and the sound collection space audio signal (10) decreases by using the sound collection space audio signal (10) and the transfer function (13).
