    摘要： In a digital information system for realizing the sale of information or the like having a commercial value in the form of a digital signal, and an audio processor, and signal processor suitably used with the system, when a digital signal is received/delivered, a digital signal source is connected directly to a player (101) for receiving and storing a specified information, which is reproduced by the player independently. A voice interval of a digital audio signal is processed to realize the slow and fast playback. The system includes a data compressor and a data extender of simple configuration. The value of the digital signal received/delivered can be exhibited directly. A selling system is constructed easily, and the player is simple in configuration and easy to operate by anyone. The fast and slow playback are possible without deteriorating the sound quality, and ripples can be greatly reduced against the digital input signal, thereby making possible a faithful data compression of an acoustic signal or the like by a simple configuration. The self-diagnosis function permits the use of a defective memory chip, thereby leading to a very economical system.

    摘要翻译： 在用于实现具有数字信号形式的商业价值的信息等的数字信息系统以及与系统适当使用的音频处理器和信号处理器的情况下，当接收/传送数字信号时， 数字信号源直接连接到播放器（101），用于接收和存储由玩家独立再现的指定信息。 处理数字音频信号的语音间隔，实现慢速，快速的播放。 该系统包括数据压缩器和简单配置的数据扩展器。 接收/传送的数字信号的值可以直接显示。 销售系统易于构建，玩家配置简单，易于操作。 快速和慢速播放是可能的，而不会降低声音质量，并且相对于数字输入信号可以大大降低纹波，从而可以通过简单的配置使声信号等的忠实数据压缩成为可能。 自诊断功能允许使用有缺陷的存储器芯片，从而导致非常经济的系统。
