Abstract

When a correlation between an L channel and an R channel of a reproduction-target sound source is considerably high, virtual sound obtained from a reproduction signal is often more likely to be localized inside the head of a listener. A device includes: a correlation analysis unit () that analyzes a degree of correlation between a surround L channel signal (SL signal) and a surround R channel signal (SR signal); and an output signal control unitthat controls, based on the degree of correlation between the SL signal and the SR signal obtained as a result of the analysis performed by the correlation analysis unit (), a ratio between: the signals outputted from a front L speaker () and a front R speaker (); and the signals outputted from a near-ear L speaker () and a near-ear R speaker ().
