Abstract

PURPOSE:To prevent generation of an abnormal sound at a connecting point, by gradually connecting a level difference at the connecting point, like delta modulation. CONSTITUTION:A difference of amplitude of two continuous sampling values (n), (n+1), which have been sampled by a sampling period and quantized and PCM- coded in the proximity of an editing connecting point detection control signal, is divided 64, 65 into polarity and absolute value information. Subsequently, a step DELTA which has been set in advance is compared 66 with a absolute value, and in case the absolute value is larger than DELTA, by its polarity, the step DELTA is added 69 to the sampling value (n) when the polarity is positive, and is subtracted 68 when it is negative, which is made the sample value (n+1). Also, when the absolute value is smaller than or equal to DELTA, the sampling value (n+1) is obtained by adding zero to the sampling value (n).
