    • An audio signal recording and reproducing apparatus can perform realtime processing with a structure having a low cost. The audio signal recording and reproducing apparatus records a series of input audio signals as digital audio data, and reproduces and outputs the input signals using the recorded digital audio data as output audio signals. An input audio signal processing unit converts the series of input audio signals into digital audio data. A data file recording unit records the digital audio data, as digital audio data file information, on a recording medium, the recording medium having a plurality of clusters in which data having a predetermined number of bytes is recorded, the digital audio file information being recorded over a plurality of clusters. A file management information recording unit records on the recording medium file management information representing the reproducing order of the clusters in which the digital audio data file information is recorded. A directory information recording unit records on the recording medium directory information including at least the number of the first cluster recorded first when the digital audio data is recorded. A reproduction procedure file information recording unit records on the recording medium the reproduction procedure file information including at least the number of the first cluster of a digital audio data file to be reproduced. An output audio signal processing unit converts digital audio data, which is read out from the recording medium in accordance with the reproduction procedure file information, into output audio signals.
    • 音频信号记录和再现装置可以以低成本的结构执行实时处理。 音频信号记录和再现装置将一系列输入音频信号记录为数字音频数据,并使用记录的数字音频数据作为输出音频信号再现和输出输入信号。 输入音频信号处理单元将一系列输入音频信号转换为数字音频数据。 数据文件记录单元将作为数字音频数据文件信息的数字音频数据作为数字音频数据文件信息记录在记录介质上,具有多个簇的记录介质,其中记录了具有预定字节数的数据,记录了数字音频文件信息 在多个簇上。 文件管理信息记录单元记录表示记录有数字音频数据文件信息的集群的再现顺序的文件管理信息。 目录信息记录单元在记录数字音频数据时记录至少包括首先记录的第一簇的数量的目录信息。 再现程序文件信息记录单元在记录介质上记录包括至少要再现的数字音频数据文件的第一簇的数量的再现过程文件信息。 输出音频信号处理单元将根据再现过程文件信息从记录介质读出的数字音频数据转换为输出音频信号。

    • A window glass antenna system includes a defogging heater pattern disposed on a window glass pane and being operable also as an AM broadcast receiver antenna, an impedance matching circuit having two inductors for respectively causing series resonance and parallel resonance of AM broadcast signals fed from an output of the heater pattern and being designed to supply the AM broadcast signals to an associated radio receiver, and at least one capacitor disposed between the heater pattern output and the impedance matching circuit for blocking induced noises of AM frequency band. With this arrangement, it becomes possible to significantly attenuate noises of AM frequency band to be induced into the heater pattern, without attenuating received signals of AM broadcast, whereby AM broadcast radio reception of good S/N ratio is enabled.
