Abstract: PURPOSE:To obtain a decoding waveform having a high quality by smoothing a crest part whose waveform is steep so that encoding can be executed optimumly although a high frequency component drops to some extent. CONSTITUTION:Local decoded values of 2 samples before and one sample before go into registers 43, 44, respectively, and in a decoding part, first of all, when a sample point has an extreme value by an extreme value deciding circuit 42 and also, it becomes an extreme value even if the residual is brought to 1/n, encoding is executed after the residual is brought to 1/n, and from this encoded value, two samples of the end of one frame are decoded, and its decoded value is given to the registers 43, 44 when one frame has ended. A local decoded value of two samples before of an output of this register 43, and an input signal are added to each other, and subsequently, brought to 1/2. Accordingly, values of the input sample and two samples before are averaged as a result. A value which has subtracted a local decoded value of one sample before being an output of the register 44 from said average is compressed successively by an adaptive difference bit. In such a way, a crest part whose voice waveform is steep can be smoothed before encoding, and a decoding waveform having a high quality can be obtained.
