Abstract
The present technology relates to a transaural processing unit that 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. The second acoustic signal contains attenuated components in a first band and a second band. The first band is the lowest band and the second band is the second lowest band in a range of a 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 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.
