PROBLEM TO BE SOLVED: To provide a music reproducer by which an error when data is transmitted is interpolated without generating a distortion in a reproduction waveform and an error is reported to a user when the error exists. SOLUTION: An input signal deciding part U1 detects the error of an input signal, extends the frequency axial/time-axial data conversion processing period of an immediately last frame and a window processing period in response to a plurality of sound frames when the error is comprised and, then, generates sound data which is continuous in terms of waveform. Silent compression data and compression data of an alarm sound are recorded in a storage means, one of frequency axial data, silent data and alarm sound data of the immediately last frame is selected by an error state through the use of a selecting means U6 and, then, a sound data generation processing is performed. |
