    Abstract: The present technology relates to a decoding apparatus, a decoding method and a program which make it possible to obtain sound with higher quality. A demultiplexing circuit demultiplexes an input code string into a gain code string and a signal code string. A signal decoding circuit decodes the signal code string to output a time series signal. A gain decoding circuit decodes the gain code string. That is, the gain decoding circuit reads out gain values and gain inclination values at predetermined gain sample positions of the time series signal and interpolation mode information. An interpolation processing unit obtains a gain value at each sample position between two gain sample positions through linear interpolation or non-linear interpolation according to the interpolation mode based on the gain values and the gain inclination values. A gain applying circuit adjusts a gain of the time series signal based on the gain values. The present technology can be applied to a decoding apparatus.

  • Patent number: 9998845
    Abstract: The present technology relates to an information processing device and method for allowing a sound image to be localized with higher precision, and a program. When a target sound image is outside a mesh, the target sound image is moved in a vertical direction while a position in a horizontal direction of the target sound image remains fixed, so that the target sound image is present on a boundary of the mesh. Specifically, a mesh detection unit detects a mesh including a position in the horizontal direction of the target sound image. A candidate position calculation unit calculates a position that is a movement target of the target sound image, based on loudspeaker positions that are at opposite ends of an arc of the detected mesh that is a destination, and the position in the horizontal direction of the target sound image. As a result, the target sound image can be moved onto a boundary of the mesh. The present technology is applicable to a sound processing device.

  • Patent number: 9922660
    Abstract: The present technology relates to a device, a method, and a program for expanding a frequency band, which are capable of obtaining high-quality sound with a small processing amount. A low band extraction band-pass filter processing unit passes a predetermined band of a low band of an input signal and generates a low band sub band signal. A band-pass filter calculation circuit calculates band-pass filter coefficients of band-pass filters having sub bands of high bands as a pass band based on an estimate value of high band sub band power, and an addition unit obtains one filter coefficient by adding the band-pass filter coefficients. A poly-phase configuration level adjustment filter performs up-sampling and level adjustment by performing filtering on a flattened signal obtained from a low band sub band signal using the filter coefficient obtained by the addition unit, and generates a high band signal. An addition unit obtains an output signal by adding the high band signal to the low band signal.
