摘要：In a digital information system for realizing the sale of information or the likehaving a commercial value in the form of a digital signal, and an audio processor, andsignal 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 aspecified information, which is reproduced by the player independently. A voice intervalof a digital audio signal is processed to realize the slow and fast playback. The systemincludes a data compressor and a data extender of simple configuration. The value of thedigital signal received/delivered can be exhibited directly. A selling system is constructedeasily, and the player is simple in configuration and easy to operate by anyone. The fastand slow playback are possible without deteriorating the sound quality, and ripples canbe 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 veryeconomical system.
