Chroma and Rhythm Oriented Music Paste

In this thesis, we provide a tool for automatically choosing proper music clips from a given audio clip collections and combining the chosen clips together as euphonious as possible. To seamlessly concatenate two different music clips without causing any audible defect is really a hard nut to crack. The main difficulty lies in the gap between human feeling and computer hearing. Since whether the combined music euphonious or not highly depends on human’s feeling, we conduct subjective evaluation on the correlation between pasting methods and auditory quality of combined clips. The experimental results show that the automatically generated music pastes are acceptable to most of the evaluators. The proposed system can be used to generate lengthened or shortened background music and dancing suite, which is useful for some audio-assisted multimedia applications.
