PROBLEM TO BE SOLVED: To prevent a decoding processing means from decoding and reproducing abnormal data at the point of time for switching encoded data sequences even when performing decoding by utilizing correlation between frames. SOLUTION: When sound encoded data to be supplied to a sound decoding processing part 17A is switched between received sound encoded data and stored sound encoded data, a data switching correcting part 15A replaces the first frame after the switching with a specific pattern P. In the sound decoding processing part 17A, when a comparator 17b detects the specific pattern P, an initialization signal is given to a sound decoding processing core part 17c to initialize an internal state storage memory 18. |
