Patent number: 10587976Abstract: The present technology relates to a sound processing apparatus and method, and a program for enabling more stable localization of a sound image. A virtual speaker is assumed to exist on the lower side among the sides of a tetragon having its corners formed with four speakers surrounding a target sound image position on a spherical plane. Three-dimensional VBAP is performed with respect to the virtual speaker and the two speakers located at the upper right and the upper left, to calculate gains of the two speakers at the upper right and the upper left and the virtual speaker, the gains being to be used for fixing a sound image at the target sound image position. Further, two-dimensional VBAP is performed with respect to the lower right and lower left speakers, to calculate gains of the lower right and lower left speakers, the gains being to be used for fixing a sound image at the position of the virtual speaker.Type: GrantFiled: January 15, 2019Date of Patent: March 10, 2020Assignee: Sony CorporationInventors: Yuki Yamamoto, Toru Chinen, Runyu Shi, Mitsuyuki Hatanaka

Publication number: 20190355368Abstract: A signal processing device, method, and program that may obtain audio at a higher audio quality when decoding an audio signal. An envelope information generating unit generates envelope information representing an envelope form of high frequency components of an audio signal to be encoded. A sine wave information generating unit extracts a sine wave signal from the high frequency components of the audio signal, and generates a sine wave information representing an emergence start position of the sine wave signal. An encoding stream generating unit multiplexes the envelope information, the sine wave information, and low frequency components of the audio signal that have been encoded, and outputs an encoding stream obtained as the result. The high frequency components included in the sine wave signal may be predicted at a higher accuracy from the envelope information and the sine wave information at the receiving side of the encoding stream.Type: ApplicationFiled: July 30, 2019Publication date: November 21, 2019Applicant: Sony CorporationInventors: Mitsuyuki Hatanaka, Toru Chinen

Patent number: 10446160Abstract: The present technology relates to a coding device and method, and a decoding device and method, and a program capable of reducing the amount of calculations for decoding. A separating unit separates a supplied bit stream into coded data of channel sources including a dialog source, coded data of additional data sources, and coded data of dialog information. A dialog information decoding unit decodes the coded data of the dialog information. When the dialog information acquired by the decoding is presented to a viewer, the viewer selects one source from the dialog source and some additional dialog sources. An additional dialog source decoding unit decodes only the coded data of an additional dialog source selected by the viewer. An additional dialog selection unit outputs a viewer-selected audio signal from among the audio signals of the dialog source and additional dialog sources in response to the selection instruction of the viewer.Type: GrantFiled: August 31, 2018Date of Patent: October 15, 2019Assignee: Sony CorporationInventors: Toru Chinen, Mitsuyuki Hatanaka, Minoru Tsuji, Hiroyuki Honma

Publication number: 20190164558Abstract: A method, system, and computer program product for processing an encoded audio signal is described. In one exemplary embodiment, the system receives an encoded low-frequency range signal and encoded energy information used to frequency shift the encoded low-frequency range signal. The low-frequency range signal is decoded and an energy depression of the decoded signal is smoothed. The smoothed low-frequency range signal is frequency shifted to generate a high-frequency range signal. The low-frequency range signal and high-frequency range signal are then combined and outputted.Type: ApplicationFiled: January 31, 2019Publication date: May 30, 2019Applicant: Sony CorporationInventors: Yuki Yamamoto, Toru Chinen, Mitsuyuki Hatanaka

Patent number: 10304466Abstract: The present technique relates to a decoding device, a decoding method, an encoding device, an encoding method, and a program which can obtain a high-quality realistic sound. The encoding device stores speaker arrangement information in a comment region in a PCE of an encoded bit stream and stores a synchronous word and identification information in the comment region such that other public comments and the speaker arrangement information stored in the comment region can be distinguished from each other. When an encoded bit stream is decoded, it is determined whether the speaker arrangement information is stored on the basis of the synchronous word and the identification information stored in the comment region. Audio data included in the encoded bit stream is output according to the arrangement of the speakers corresponding to the determination result. The present technique can be applied to an encoding device.Type: GrantFiled: August 3, 2016Date of Patent: May 28, 2019Assignee: Sony CorporationInventors: Mitsuyuki Hatanaka, Toru Chinen
