摘要:
A voice recording/reproducing apparatus includesan A/D converting circuit for converting an input analog voice signal into a digital signal;a digital signal processing circuit for coding the converted digital signal in a predetermined format and decoding the coded voice data;a recording medium for storing the coded voice data;a buffer memory;a D/A converter for converting the decoded digital signal stored in the recording medium into an analog voice signal;an operation unit for setting a predetermined mode; anda control circuit for performing a predetermined process for reducing noise in a reproducing operation to the voice data obtained from time a predetermined period of time before the operation unit recognizes that a recording stop operation is performed by the operation unit during a recording operation to time when the operation unit recognizes that the recording stop operation is performed whereby the noise due to a stop operation is reduced when the voice data is in said buffer memory and then transferred to the recording medium.
