SOUND FIELD REPRODUCING METHOD

摘要

PURPOSE:To facilitate a system in which a listener has an experience sound in almost the same state as if the listener were resident in a room to be realized by using a transfer function for each speaker and a signal from a sound source and generating a signal to be reproduced from a relevant speaker. CONSTITUTION:When an arrangement beta of the system comprising N channels is given, a signal relating to direction information is distributed to a speaker whose reproduction area is represented in the direction information to generate a transfer function of the speaker. The transfer function of each speaker is generated from the transfer function of a direction transmission number generating circuit 7 including the direction information of a specific sound field depending on the number and arrangement of speakers 3-1 to 3-N of the reproduction system. Even when the number and arrangement of the speakers of the reproduction system are not match with the number of sound incoming directions and how to decide the area, the listener can has an experience in the same state as if the listener were resident in a room condition to be realized.
