Abstract:
The present technology relates to an acoustic signal processing device, an acoustic signal processing method, and a program capable of improving a feeling of localization of a sound image at a position deviated leftward or rightward from a median plane of a listener. A transaural processing unit performs a predetermined transaural process for an input signal by using a sound source opposite side HRTF and a sound source side HRTF to generate a first acoustic signal, and a second acoustic signal containing attenuated components in a first band which is the lowest band, and a second band which is the second lowest band in a range of a predetermined first frequency or higher frequencies, in bands of appearance of notches in the sound source opposite side HRTF. A subsidiary signal synthesis unit adds a first subsidiary signal constituted by a component in a predetermined band of the second acoustic signal to the first acoustic signal to generate a third acoustic signal. The present technology is applicable to an AV amplifier, for example.

Claim (Index 13):
The acoustic signal processing device according to  claim 12 , further comprising: an addition unit that adds the first acoustic signal and the fourth acoustic signal and adds the second acoustic signal and the third acoustic signal when positions of the first virtual sound source and the second virtual sound source are separated into a left side and a right side with respect to the median plane, and adds the first acoustic signal and the third acoustic signal and adds the second acoustic signal and the fourth acoustic signal when the first virtual sound source and the second virtual sound source are disposed on the same side with respect to the median plane.
