Abstract: The present technology relates to a signal processing device, a method thereof, and a program capable of acquiring a characteristic of a plurality of speakers more easily. A signal processing device includes a correction value calculation unit configured to calculate, for every plurality of speakers having a substantially same emission characteristic, the speakers forming a speaker array, a gain correction value of each of the speakers on the basis of acoustic characteristic data acquired by collecting a sound from the speakers at a plurality of measurement points and the emission characteristic. The present technology is applicable to a measurement system.

Abstract: To appropriately generate evaluation data to be compared with user input data. An information processing device includes a comparison unit that compares evaluation data generated on the basis of first user input data with second user input data.

Abstract: Provided is a signal processing device including: a reverberation sound signal generation unit that generates a reverberation sound signal according to a sound source position of a virtual sound source and a distance to a reference point; and a drive signal generation unit that generates a drive signal for a speaker array by a wavefront synthesis filter, in which the drive signal generation unit generates the drive signal on the basis of a signal obtained by performing wavefront synthesis filtering processing on a signal obtained by convolving the reverberation sound signal with a signal of the virtual sound source and/or a signal obtained by performing wavefront synthesis filtering processing on the reverberation sound signal to make the reverberation sound signal into a virtual sound source.

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 apparatus, a signal processing method, and a program that make it possible to reduce an amount of computation for wavefront synthesis. The signal processing apparatus includes a reproduction speaker selection section. According to a position of a virtual sound source and a range of a listening area, the reproduction speaker selection section selects, from a plurality of speakers included in a speaker array, a plurality of reproduction speakers to be used for reproducing a sound based on an audio signal of the virtual sound source. The present technology can apply to the signal processing apparatus.

Abstract: A sound source setting section and a listening setting section are each configured to have a parameter setting section, a display section, and an arrangement relocation section on a placing surface of a placing table in real space, the arrangement relocation section allowing the source setting and listening sections to relocate on the placing surface. A reflecting member to which a reflecting characteristic is assigned is configured to be placeable on the placing table. A mixing process section performs a mixing process and also generates an image at the position, in a virtual space, of the sound source setting section relative to the listening setting section, the image having a texture indicative of a sound source assigned to the sound source setting section. Sound mixing with respect to a free listening point is thus performed easily.
