PROBLEM TO BE SOLVED: To prevent the occurrence of abnormal sound even though a miss occurs in error detection. SOLUTION: An audio decoding section 21 is used to decode spectrum data in a frame unit from audio coded data. In an error compensation section 23, a frame in which an error is detected by an error compensation section 23 and frames located in front of and the back of the frame are recognized as erroneous frames, an interpolating process is conducted for the error frames employing the data of a normal frame. The spectrum data outputted from the section 23 are successively converted from frequency region data to time region data and decoded audio data are outputted. |
