Embodiment Construction
[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0047] Such as figure 1 As shown, it is a schematic flow chart of the main melody track identification method of the present invention. In the present invention, it is required to traverse the n notes of each section of the track in each piece of music, and utilize the MIDI file to obtain the velocity v in the note information i , time value d i , time value type dt i and pitch p i , it is required to calculate the average velocity v, the total duration of notes d, the set of note duration types dus, the maximum interval interval and the second interval sec_interval.
[0048] MIDI files record the sequence of music performance instructions, including music score information, which provides convenience for music information extraction. Therefore, using MIDI files as a data source can directly extract the basic information of music....
