<P>PROBLEM TO BE SOLVED: To decrease kinds of devices prepared for coping with faults when a sound field controller is constituted by making a plurality of devices take partial charge of functions. <P>SOLUTION: A common sound field device performs processing according to algorithm for a master to function as a master device 3 generating a reflected sound signal of a sound collection signal from a microphone and also performs processing according to algorithm for a slave to function as a 1st slave device 5 to a 3rd slave device 7 which generate output signals to respective speakers from the reflected sound signal and an inputted sound signal. Consequently, they can cope with faults by preparing the common sound field device. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
