Abstract: PURPOSE:To provide the solid state stereophonic speech recording and reproducing device which is expected to be applied to a conversation recording and reproducing device such as a dictating machine. CONSTITUTION:Speech signals L and R gathered by microphone input parts 1L and 1R are converted in A/D by A/D converters 2L and 2R to generate digital signals X and Y.

The 1st and 2nd compressors 4A and 4B compresses the input signals by, for example, adaptive difference PCM to generate compressed data X' and (X-Y)'. The data X' and (X-Y)' are written in a memory 6 by a memory controller 5. For reproduction, the compressed data read out by the memory controller are expanded by 1st and 2nd expanders, a subtracter calculates Y from the expanded data X and (X-Y), and then a D/A converter regenerates the X and Y into speech signals L and R.
