Title:
RECORDING REGENERATING DEVICE
Document Type and Number:
Japanese Patent JP3852890
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To solve the problem of poor sound quality and effectively utilize a memory to improve the function of a device by providing a circuit for processing the output of an A/D converter as the information not subjected to compression by a circuit of another system simultaneously with the output to a digital signal processor.
SOLUTION: When a recording is instructed to a control circuit M0 by a key input means K1, voice information is inputted from an analog input circuit A1, and 16-bit digital information is outputted to a voice compressing and extending circuit D1 every 48 kHz by an A/D converting circuit A3. In this recording regenerating machine, the 16-bit digital information is also transmitted to a sampling converting circuit D2. The sampling converting circuit D2 performs, for example, the processing of curtailing it from 48 kHz to 8 kHz. Accordingly, in recording, compressed information and non-compressed low sampling information are simultaneously inputted to the control circuit M0. The control circuit M0 sequentially writes the data to memory chips M1-Mn.
