    • PROBLEM TO BE SOLVED: To precisely detect tempo of music with a small operation amount.SOLUTION: A basic feature amount extraction part 100 calculates plural kinds of basic feature amounts on every frame from input audio signal (PCM signal). Assuming that the plural kinds of basic feature amounts extracted by the basic feature amount extraction part 100 on every frame as time-series data, a temporal BPM (beats per minute) calculation section 200 detects cyclic component (repetitive component) included in weighting addition signal of the plural kinds of basic feature amounts and calculates the temporal BPM. The BPM calculation section 200 calculates beats per minute (BPM) based on the basic feature amounts extracted by the basic feature amount extraction part 100. The BPM calculation section 200 determines whether the temporal BPM calculated by the temporal BPM calculation section 200 needs to be corrected, and corrects the same by multiplying by two times or 1/2 times, if necessary, and outputs the same as BPM. The weighting addition signal highlights a portion where all basic feature amounts change simultaneously. Therefore, noises are reduced and detection performance of cyclic component is increased.
    • 要解决的问题:以小的操作量精确地检测音乐的速度。 解决方案:基本特征量提取部分100从输入音频信号(PCM信号)计算每帧的多种基本特征量。 假设由基本特征量提取部100在每帧中提取的多种基本特征量作为时间序列数据,时间BPM(每分钟次数)计算部200检测加权相加信号中包含的循环分量(重复分量) 的多种基本特征量,并计算时间BPM。 BPM计算部分200基于由基本特征量提取部分100提取的基本特征量来计算每分钟的节拍(BPM).BMM计算部分200确定是否需要校正由时间BPM计算部分200计算出的时间BPM ,如果需要,通过乘以2倍或1/2倍来校正相同,并输出与BPM相同的值。 加权附加信号突出显示所有基本特征量同时改变的部分。 因此,噪声降低,循环成分的检测性能提高。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To securely improve sound quality of audio. SOLUTION: A classification section 181 classifies a musical piece based on an audio data of a supplied musical piece. A switching control section 182 controls a switching section 183 for switching an output point of the audio data, according to a classification result of the musical piece. The switching section 183 supplies the supplied audio data to any of a frequency band spread section 188, a time band spread section 189, or time/frequency band spread section 190. A frequency band spread section 188 performs band spreading of the musical piece in a frequency domain, and a time band spread section 189 performs band spreading of the musical piece in a time domain. The time/frequency band spread section 190 performs band spreading of the musical piece in both domains of the frequency domain and the time domain. COPYRIGHT: (C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To suppress expansion/contraction fluctuation of output sound in performing pitch conversion of a sound signal.SOLUTION: A sound processing device includes a pitch conversion unit, an error detection unit, a time length control unit. The device may further include a time expansion/contraction processing unit and a thinning-out/insertion unit. The error detection unit calculates a difference from an expected value of the sample number of an output sound signal, based on each sample number of an input sound signal before pitch conversion, an output sound signal after the pitch conversion and an unprocessed input sound signal. The pitch conversion unit subjects the input sound signal to the pitch conversion. The time expansion/contraction processing unit subjects the pitch-converted sound signal to time expansion/contraction processing. The thinning-out/insertion unit generates the output sound signal by thinning out or inserting a sample from or into the sound signal by the calculated difference according to control by the time length control unit. Accordingly, when the difference is calculated from the sample number of the sound signal in each state, the time length of the sound signal can be correctly adjusted to suppress expansion/contraction fluctuation. The device is applicable to a pitch conversion device.
    • 要解决的问题:抑制在执行音频信号的音调转换中的输出声音的扩张/收缩波动。 解决方案:声音处理装置包括音调转换单元,错误检测单元,时间长度控制单元。 该装置还可以包括时间扩展/收缩处理单元和稀疏/插入单元。 误差检测单元基于音调转换之前的输入声音信号的每个采样数,音调转换之后的输出声音信号和未处理的输入声音信号来计算与输出声音信号的采样数量的期望值的差。 音调转换单元使输入声音信号进行音调转换。 时间扩展/收缩处理单元对音调转换的声音信号进行时间扩展/收缩处理。 稀疏/插入单元根据时间长度控制单元的控制,通过将声音信号中的样本稀疏或插入到计算出的差值来产生输出声音信号。 因此,当在每种状态下根据声音信号的采样数计算差时,可以正确地调整声音信号的时间长度以抑制扩张/收缩波动。 该装置适用于音高转换装置。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an electronic device capable of increasing flexibility of device arrangement inside an apparatus for performing cooling efficiently, of facilitating turning on/off operation of a power switch in the apparatus, and of simplifying wiring. SOLUTION: In a personal computer 100, a device which generates a large quantity of heat and is hardly touched by a user, is arranged in a main unit 200, while a drive device for a removable storage medium, which generates a small quantity of heat and frequently accessed by the user, is arranged in an access unit 300. Since the power switches are arranged in both of the main unit 200 and the access unit 300, flexibility of device arrangement inside the personal computer 100 is increased for performing cooling efficiently, and the power of the personal computer 100 can be turned on/off easily.
