Title:
ACOUSTIC SIGNAL PROCESSING DEVICE AND ACOUSTIC SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/052226
Kind Code:
A1
Abstract:
Disclosed is an acoustic signal processing device such that, when the correlation between the L channel and the R channel of a reproduced sound source is extremely high, lateralization of a virtual audio image of a reproduced signal often occurs. The device is provided with a correlative relationship analysis unit (3) which 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 unit (4) which, in response to the degree of correlation between the SL signal and the SR signal, that is, the analysis result of the correlative relationship analysis unit (3), controls the ratio between the signals output from a front L speaker (7) and a front R speaker (8) which are located forward from the listening position, and the signals output from an ear proximate L speaker (9) and an ear proximate R speaker (10) which are located near the ears of the listener.
