PROBLEM TO BE SOLVED: To stably generate a compensation signal for compensating the quality of signals of a plurality of channels while suppressing the increase in operation quantity following increase of the number of channels.SOLUTION: The audio signal output device 1A includes: a plural-channel audio signal holding unit 101 for holding a plural-channel audio signal for a predetermined period; a quality control unit 102 for determining whether the plural-channel audio signal is degraded on the basis of predetermined information for quality control; a correlation detection unit 103 that detects the correlation between the channels from the plural-channel audio signal when it is determined that the plural-channel audio signal is degraded; a compensation signal generating method determination unit 104 for determining a generating method of a compensation signal on the basis of a detection result of the correlation; a compensation signal generating unit 105 for generating the compensation signal on the basis of the determined generating method; and a signal output unit 106 that outputs the generated compensation signal and outputs the plural-channel audio signal when it is determined that the plural-channel audio signal is not degraded. |
