Abstract
A signal processing device includes: a calculating unit performing calculation using signal levels of first and second acoustic signals; a determining unit, based on a result of a comparison between: the signal level of at least one of the first and second acoustic signals before the calculation; and a result of the calculation, determining whether a component of a third acoustic signal to be output from a position between a position from which the first acoustic signal is output and a position from which the second acoustic signal is output is included in the first and second acoustic signals; and a signal generating unit generating the third acoustic signal from the first and second acoustic signals when the determining unit determines that the component of the third acoustic signal is included in the first and second acoustic signals.
