<P>PROBLEM TO BE SOLVED: To provide an audio signal mixing device which can mix the original digital audio signal so as to be restorable. <P>SOLUTION: An audio signal mixing device 1 comprises mixing means 10 for mixing a digital audio signal on the basis of the panning coefficient for each output channel assigned to an input channel, pilot signal generation means 11 for generating a pilot signal having the panning coefficient as an amplitude by assigning, for each output channel, the panning coefficient of the input channel that is assigned to the output channel, to a predetermined frequency which is higher than a predetermined frequency and different for each input channel, and adding means 12 for adding the pilot signal to the digital audio signal of an output channel mixed by the mixing means 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
