摘要： Original voice uttered in a first space is acquired via a microphone and a series of digital waveform data of the acquired original voice are obtained. The waveform data are sequentially segmented into plural frames and the waveform data of the individual frames are written into a memory. In parallel with writing, into the memory, of the waveform data, individual ones of the frames already written in the memory are sequentially or randomly selected and read out in a direction opposite to a direction the waveform data of the frame have been written so that a reverse-reproduced voice signal is generated. As the original voice is transmitted, as a leaked voice from the first space to a second space near the first space, a scrambling voice based on the reverse-reproduced voice signal is spatially mixed with the leaked voice in the second space.

摘要： Whereas a high masking effect can be secured in a space to which a masking sound is emitted, the degree of a discomfort a person existing in the space suffers can be reduced. In superimposition processing, a CPU 21 extracts sound signals in different intervals of a sound signal X12-n of a human voice, superimposes the extracted sound signals on each other on the time axis, and outputs a resulting superimposed sound signal X13-n. In shift and addition processing, the CPU 12 interchanges a sound signal, before a reference position, of a sound signal X16-n and a sound signal, after the reference position, of the sound signal X16-n (shift processing) and outputs a sound signal X17-n obtained by adding together a shift-processed sound signal X16′-n and the original, non-shift-processed sound signal X16-n.

摘要： In a masker sound generation apparatus, an acquisition part acquires a sound signal, and a generation part generates a masker sound signal based on the acquired sound signal. Specifically, the generation part divides the sound signal acquired by the acquisition part into a plurality of sections each having a predetermined time length, then repeats a sorting process of sorting the divided sections as a process of changing the sequence of arrangement of the sound signal, and alters a manner of sorting the sections each time the sorting process is repeated.

摘要： The technical field of the invention generally concerns systems for receiving and transmitting compressed video and audio data. In particular, a subscriber system (10) includes a communication subsystem (12) to receive compressed data from and transmit compressed data to a ISDN primary access line (14) utilizing the "bandwidth on demand" feature of that communication channel. The communication subsystem (12) separates received compressed data into compressed video data and compressed audio data. Within the subscriber system (10), the compressed video data is transmitted to a programmable video data format conversion subsystem (28) for decompression and production of a visible image on a CRT (82). Similarly, compressed audio data is transmitted to a programmable audio data format conversion subsystem (192) for decompression and production of an audible sound on a speaker (262). Compressed data of visible images and audible sounds may also be obtained with and transmitted from the subscriber system (10).
