ABSTRACT: Onset and pitch are the most important properties of music signal, which is the basic

information of high-level musical processing tasks. Recently, most of researches about onset detection

and fundamental frequency estimation have nothing to do with each other. In fact, both of them are

influenced by other one. The frame size determines the frequency resolution, but too large frame might

cover consecutive notes, which will cause complex spectrum that make the ...
