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 8):
The acoustic signal processing device according to  claim 7 ,\n wherein the first binaural processing unit generates a third binaural signal that contains attenuated components in the first band and the second band of the first binaural signal, and the crosstalk correction processing unit performs the crosstalk correction process for the second binaural signal and the third binaural signal.
