Abstract: The present technology relates to a signal processing apparatus and method, and a program that can easily make a leaking sound difficult to hear.
A signal processing apparatus includes a masking sound generation unit that, in a case where a first content is reproduced in a first region and a second content is reproduced in a second region by wave field synthesis using a speaker array, generates a masking sound for masking a sound of the first content and a sound of the second content heard in a region between the first region and the second region. The present technology can be applied to content reproduction systems.

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.

Abstract: Provided is a sound field forming apparatus and method to improve reproducibility of a wave front by using a smaller amount of computation. The sound field forming apparatus includes a listener position acquisition section that acquires listener positional information indicating a position of a listener, a drive speaker selection section that selects one or a plurality of speakers, as a drive speaker, used to form a sound field, among the speakers configuring a speaker array on the basis of the listener positional information, and a drive signal generation section that drives the drive speaker and generates a speaker drive signal for forming the sound field in accordance with a selection result of the drive speaker.
