VOICE RECORDING APPARATUS

摘要

An apparatus for recording a voice signal is disclosed. The apparatus comprises a mike(1); an inverse amplifier(2) for amplifying the voice signal from the mike(1); a low pass filter(3) for filtering the noise of the voice signal; a high pass filter(4) for passing the high frequency of the voice signal; a level director(7) for directing the level of the output signal from the high pass filter(4); a microcomputer(8) for controlling a digital signal processor(6) in response to the output signal from the level director(7); an analog/digital converter(5) for converting the voice signal from the high pass filter(4) to a digital voice signal; the digital signal processor(6), responsive to the control signal from the microcomputer(8), for processing the output signal from the analog/digital converter(5) to compress the voice signal data; and a memory(9) for storing the voice signal data processed at the digital signal processor(6).
