摘要： The present technology relates to a sound processing apparatus and a sound processing system 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. The values obtained by multiplying these gains by the gain of the virtual speaker are set as the gains of the lower right and lower left speakers for fixing a sound image at the target sound image position. The present technology can be applied to sound processing apparatuses.

摘要： There is provided an audio coding device which appropriately sets the quantization bit number by a small calculation amount in each stage when coding an input audio signal by performing multi-stage normalization/quantization. A quantization information calculation section determines total quantization information idwl0, based on normalization information idsf, and allocates the total quantization information idwl0 for quantization information idwl1 and quantization information idwl2. At this time, the quantization information calculation section limits the quantization information idwl1 by a limiter lim1, and allocates the total quantization information idwl0 for quantization information idwl1. If the quantization information idwl1 exceeds the limiter lim1, the excess is allocated for the quantization information idwl2. A first normalization section and a first quantization section normalizes and quantizes a frequency spectrum mdspec1 in the first stage. A second normalization section and a second quantization section normalizes and quantizes a differential frequency spectrum mdspec2 in the second stage.

摘要： A non-transitory computer-readable storage medium is provided for storing computer program instructions that cause a computer to implement a method of exchanging content. The method includes connecting to an information processing apparatus, and transferring a ID of the computer to the information processing apparatus when a connection to the information processing apparatus is detected. The method further includes storing content and data related to the content transmitted from the information processing apparatus, transferring the data corresponding to the content stored in the computer, and reproducing the stored content. The content is automatically transferred to the computer when the computer is judged to be a predetermined device.

摘要： 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.

摘要： The present invention pertains to an encoding device and method, a decoding device and method, and to a program, with which sound of an appropriate volume level can be obtained with a smaller quantity of codes. A first gain calculation circuit calculates a first gain for volume level correction of an input time series signal, and a second gain calculation circuit calculates a second gain for volume level correction of a downmixed signal obtained by downmixing of the input time series signal. A gain encoding circuit computes the gain differential between the first gain and the second gain, the gain differential between time frames, and the gain differential within time frames, and encodes the first gain and the second gain. The present invention can be applied in encoding devices and decoding devices.

摘要： The present technology relates to an audio signal output device and a method, an encoding device and a method, a decoding device and a method, and a program for realizing audio reproduction with a more realistic feeling.In a case where an audio signal generated to be output as a sound from an ideal speaker that is a virtual speaker placed in an ideal position is input, the distance between the ideal speaker and a real reproduction speaker is determined. Gain adjustment is then performed on the audio signal with the gain corresponding to the determined distance, the audio signal subjected to the gain adjustment is reproduced by the reproduction speaker. Accordingly, even in a case where there is a difference in position between the ideal speaker and the reproduction speaker, audio reproduction with a more realistic feeling can be realized. The present technology can be applied to reproduction devices.
