PROBLEM TO BE SOLVED: To solve the problem that a frame error cannot be corrected even when the frame error occurs. SOLUTION: A error detecting circuit 30, which detects the error frame from audio data constituted with serial frames; and an interpolation circuit 70, which reads out the front frame and the rear frame of the error frame detected by the error detecting circuit from a third frame memory 13 and a fifth frame memory 15, generates a synthesized frame based on the front frame and the rear frame, and stores and renews the synthesized frame in a fourth frame memory 14 in order to interpolate the synthesized frame between the front and the rear frames of the error frame; are provided. |
