Abstract
The present technology relates to a signal processing device, a signal processing method, and a program that can provide sound with more increase in realistic sense by restoring a difference of sound pressure between sound sources. The signal processing device includes: an acoustic signal obtaining unit that obtains an acoustic signal; a sound source positional information obtaining unit that obtains sound source positional information relating to a distance between a sound source and a sound collecting unit that collects sound from the sound source; a listening positional information obtaining unit that obtains listening positional information relating to a distance between a reproducing device that reproduces the acoustic signal and a listener who listens to sound reproduced by the reproducing device; and a correcting unit that corrects gain of the acoustic signal on a basis of the sound-source positional information and the listening positional information. The present technology can be applied to, e.g., a TV telephone system.
