摘要： PROBLEM TO BE SOLVED: To achieve joining of 1-bit signals produced respectively at different sampling frequencies in an integer multiple relation to each other without causing noise. SOLUTION: Upon the receipt of a switching request signal 302, a controller 13 controls switching of a changeover switch 15 to provide an output of a switching output signal 305 resulting from smoothly selecting a 64fs rate reproduction signal 300, a 64fs cross fade signal 310 and then a 64fs mute pattern signal 308. When the 64fs mute pattern signal 308 is outputted, the controller 13 generates a switching signal 306 in a properly controlled timing to allow a mute pattern generator 12 to switch the 64fs mute pattern signal 308 into a 128fs mute pattern signal 309. A temporal average of a double integral signal with a minimum repetitive pattern is equal between the mute pattern signals of the two systems. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a device for processing digital signal capable of obtaining a one-bit signal which expresses up to a signal of a large level, while realizing a low quantization noise level by a higher-order ΔΣ modulation for a signal of a small audio band signal level.
SOLUTION: The quantization bit number of a quantizer 29 is expanded to 2 bits. Once, a ΔΣ modulation signal representing the audio band signal exceeding ±1 is generated by using the fifth-order ΔΣ modulator 3 in which the quantization values are 4 values of ±1 and ±3. The signal converted into 2 bits once is reconverted into one bit signal again by a primary ΔΣ modulator 4 in the subsequent stage. The quantization value of one bit quantizer 33 in the subsequent stage is made the same value as ±1 which is the minimum quantization value of the pre-stage 2 bits quantizer 29.

摘要： PROBLEM TO BE SOLVED: To generate an output audio signal having natural directivity in response to input audio signals of 2 channels. SOLUTION: An output audio signal is generated by synthesizing, by gain adjusting at need, one or the other or both of input audio signals of 2 channels and a synthesized audio signal generated from the other or the one of the input audio signals of the 2 channels or the input audio signals of the 2 channels. A normal direction possessed by the input audio signals of the 2 channels is detected by the magnitudes of respective levels of the input audio signals of the 2 channels. Information in the detected normal direction is stored and distribution values in the normal directions in the whole directions in a predetermined time interval are calculated. Gain adjustments about corresponding audio signals are implemented by the sum total of products of the calculated distribution values in the normal direction and gains in a predetermined gain table.

摘要： PROBLEM TO BE SOLVED: To provide a stereophonic signal processing apparatus and a stereophonic signal processing method for separating a center sound signal with high sound quality and a presence acoustic signal in a stereophonic sense from 2-channel stereophonic signals. SOLUTION: The 2-channel stereophonic signals are separated into complex signals respectively comprising a plurality of bands, and a phase difference between the complex signals between both the channels is calculated by each band. A consecutive gain function whose value changes with a calculated phase difference is established, which takes 1.0 or its neighboring value when the phase difference is 0 degree and takes 0.0 or its neighboring value when the phase difference is ±180 degrees. The gain is multiplied with the complex signals found from applying arithmetic mean to both the channel signals, and thereafter the products are subjected to band composite processing to separate a signal with a component close to center localization. The presence acoustic signal is separated by subtracting the components close to the center localization from each of the 2-channel stereo signals. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a delta-sigma modulator capable of ensuring a stable 1-bit signal having less distortion at a transition time to a soundless state while maintaining high sound quality during the reproduction of an audio signal representing music or the like.
SOLUTION: A detector 34 detects a fixed pattern representing a mute pattern as a predetermined pattern and a "0" level continued for a predetermined time from an input signal. A changeover switch 33 switches the supply of a random noise signal from a random noise generator 32 to a quantizer and the suspension of the supply based on the result of the detection in the detector 34. When the detector 34 detects the predetermined pattern, the changeover switch 33 supplies the random noise signal generated by the random noise generator 32 to a quantizer 30 and when the detector 34 does not detect the predetermined pattern, the changeover switch stops the supply of the random noise signal to the quantizer 30.
