<P>PROBLEM TO BE SOLVED: To appropriately maintain a relationship of output balances in front and rear speaker groups. <P>SOLUTION: A control part 40 calculates a multiplication factor on the basis of information on an assigned position and an adjustment amount of volume distribution inputted from an indicating part 30, and the calculated multiplication factor is supplied to a volume adjusting part 50 or a volume adjusting part 60. The volume adjusting part 50 multiplies audio data of a channel 1 by the supplied multiplication factor to determine an output balance of a front speaker group. The volume adjusting part 60 multiplies the audio data of the channel 1 by the supplied multiplication factor to determine an output balance of a rear speaker group. In this case, the output balances of the front and rear speaker groups can be determined while associating the output balances with each other by the indicating part 30 giving common information to the control part 40. <P>COPYRIGHT: (C)2004,JPO |
