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 14):
The acoustic signal processing device according to  claim 12 , wherein the bands of the first subsidiary signal and the second subsidiary signal at least include the lowest band and the second lowest band in a range of a predetermined third frequency or higher frequencies in bands of appearance of the notches in a fifth head acoustic transmission function between one of the both ears of the listener and one of two speakers disposed on left and right sides with respect to the listening position, the lowest band and the second lowest band in a range of a predetermined fourth frequency or higher frequencies in bands of appearance of the notches in a sixth head acoustic transmission function between the other ear of the listener and the other of the two speakers, the lowest band and the second lowest band in a range of a predetermined fifth frequency or higher frequencies in bands of appearance of the notches in a seventh head acoustic transmission function between the other ear and the one speaker, and the lowest band and the second lowest band at a predetermined sixth frequency or higher frequencies in the bands of appearance of notches in an eighth head acoustic transmission function between the one ear and the other speaker.
