PURPOSE:To reduce the storage capacity without complicating the operation of a control section, by splitting a code series of sound signals into sound sections and non-sound sections, and storing a flag and code number information only for the non-sound section. CONSTITUTION:A code series of sound signals applied to a terminal 10 is discriminated for sound or non-sound sections at a sound detection circuit 22, and in case of the non-sound section, a counter 23 is incremented with a clock of a frequency equal to that of the sampling clock of the sound code. Further, a control circuit 24 stops the transmission of clocks to buffers 13, 14 in a computer. Thus, the sound code in the non-sound section is not stored. In case of the sound section, the control circuit 24 gives the clock to the computer 12, and a selection circuit 25 transmits a fixed pattern and the count value of the counter 23. In the sound section, sound codes are always transmitted via a delay circuit 21. |
