PROBLEM TO BE SOLVED: To provide a server separately storing audio and musical sound without increasing communication time.SOLUTION: The server uploads to a center only singing voice of a singer as audio data (a singing file) along with synchronization information of Karaoke performance. The synchronization information includes at least tempo and volume information in a Karaoke musical piece which has been performed at the time of recording the audio data. The center plays back the singing file to generate a singing audio signal, and implements Karaoke performance at the tempo and volume included in the synchronization information to generate a musical sound signal. A new sound data (mixing data) is generated by mixing the generated singing audio signal with the musical sound signal. |
