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 16):
The acoustic signal processing device according to  claim 12 ,\n wherein the first transaural processing unit includes\n a first binaural processing unit that generates a first binaural signal containing the first synthesis signal and the first head acoustic transmission function superimposed on the first synthesis signal, \n a second binaural processing unit that generates a second binaural signal which is a signal including the second synthesis signal and the fourth head acoustic transmission function superimposed on the second synthesis signal, and containing attenuated components in the third band and the fourth band of the signal, and \n a first crosstalk correction processing unit that performs a crosstalk correction process for the first binaural signal and the second binaural signal for canceling an acoustic transmission characteristic between the ear away from the first virtual sound source and one of two speakers disposed on left and right sides with respect to the listening position, which speaker is located on the side opposite to the first virtual sound source with respect to the median plane, an acoustic transmission characteristic between the ear close to the first virtual sound source and the other speaker of the two speakers, which speaker is located on the first virtual sound source side with respect to the median plane, a crosstalk from the speaker on the side opposite to the first virtual sound source to the ear close to the first virtual sound source, and a crosstalk from the first virtual sound source side speaker to the ear away from the first virtual sound source, and \n the second transaural processing unit includes\n a third binaural processing unit that generates a third binaural signal containing the second synthesis signal and the third head acoustic transmission function superimposed on the second synthesis signal, \n a fourth binaural processing unit that generates a fourth binaural signal which is a signal including the first synthesis signal and the second head acoustic transmission function superimposed on the first synthesis signal, and containing attenuated components in the first band and the second band of the signal, and \n a second crosstalk correction processing unit that performs a crosstalk correction process for the third binaural signal and the fourth binaural signal for canceling an acoustic transmission characteristic between the ear away from the second virtual sound source and one of two speakers, which speaker is located on the side opposite to the second virtual sound source with respect to the median plane, an acoustic transmission characteristic between the ear close to the second virtual sound source and the other speaker of the two speakers, which speaker is located on the second virtual sound source side with respect to the median plane, a crosstalk from the speaker on the side opposite to the second virtual sound source to the ear close to the second virtual sound source, and a crosstalk from the second virtual sound source side speaker to the ear away from the second virtual sound source.
