<P>PROBLEM TO BE SOLVED: To provide a signal processing device, a signal processing method, and a signal processing program which are capable of automatically determining audio signals other than a mixing target corresponding to a change in an external state, so as to lighten a load imposed on an operator. <P>SOLUTION: A sound adjusting/mixing device 110 mixes the audio signals of two or more channels together, and outputs the mixed audio signals to each selected from relay stations 1 to i. The device 110 is provided with a switching unit 112 selectively switching mixing target systems from one to the other so as to exclude, at least, one channel from the mixing target for each output end. A control device 120 controlling the sound adjusting/mixing device 110 is provided with an interlock condition storage unit 121 which stores an interlock condition to enable the switching unit 112 to carry out a switching operation, and a detection unit 123 where interlock conditions outputted from external units (1) to (M) are inputted and which detects a change in the interlock conditions. <P>COPYRIGHT: (C)2007,JPO&INPIT |
