CODING DEVICE, CODING METHOD, DECODING DEVICE AND DECODING METHOD

PROBLEM TO BE SOLVED: To make it possible to select either processing that considers the continuity among several files or processing that does not consider the continuity when the several files are coded or decoded. SOLUTION: A figure 14A shows conditions where, across a parting point, the PCM data in the ending point of dataA.pcm is continuous with the PCM data in the starting point of dataB.pcm. A figure 14B shows conditions of the final frame of the dataA.pcm where the data of the dataB.pcm is selected instead of covering 0 data in data outside the parting point when data lines are processed in succession. A figure 14C shows the front frame assignment of the dataB.pcm where, regarding the data outside the starting point of the dataB.pcm, the data of the dataA.pcm is selected as the processing of the frame assignment to keep the continuity with the frame assignment of the dataA.pcm, instead of covering 0 data by adjusting the frame to the starting point of the file. Such processing keeps the continuity between two files and prevents speech from breaking off when the two files are decoded and regenerated continuously.
