The authentication and integrity of digital audio are attracting more and more attention from researchers. Along with the wide use of audio processing softwares, it becomes more easily for people to tamper the audio content which makes audio forensics much harder. Many methods have been proposed to detection tampering process such as re-sampling, double-compression, copy-paste

Content-based music retrieval uses the content of music itself as query, such as rhythm, melody, chord, accompaniment, timbre etc., to get the music resource which meets the query condition or contains same or similar music clip in a music database. The audio media in the music database may be of different formats, such as MIDI,
