<P>PROBLEM TO BE SOLVED: To suppress occurrence of a sense of incongruity in a listener when changing an acoustic processing mode with a simple configuration. <P>SOLUTION: When the processing mode in a j channel is changed, a control processing part 111 first continuously reduces split ratio of a j channel signal to a speaker corresponding to the j channel from 1, and continuously increases split ratio of the j channel signal to other speaker from zero. By split ratio control, the control processing part 111 terminates first stage control to set change of the processing mode in a processing operation part for the j channel at the point when the split ratio of the j channel signal to the speaker corresponding to the j channel becomes equal to or less than a predetermined value. After that, the control processing part 111 continuously increases the split ratio of the j channel signal to the speaker corresponding to the j channel to 1 and continuously reduces the split ratio of the j channel signal to other speaker to zero. <P>COPYRIGHT: (C)2010,JPO&INPIT |
