In example, tone line generates method and includes:
101, obtaining note information sequence, in described note information sequence, each note information includes note height.
The method obtaining note information sequence has multiple.Such as, in actual application, the note information of song is stored in
In MIDI (English: Musical Instrument Digital Interface, Chinese: musical instrument digital interface) file.
MIDI is the electronic communication protocol of an industrial standard, for the performance apparatus such as electronic musical instrument (such as synthesizer) define various note or
Play code.After getting the MIDI file of song, when parsing the beginning of each note in this song from this MIDI file
Between, end time (or duration) and note height.Concrete, note height is normally in interval [21,108].Solve
After separating out the time started of each note, end time (or duration) and note height, one structure of general definition
Body stores these information.Therefore, when obtaining note information sequence, each note information can be searched from this structure.
But, although note height is normally in interval [21,108], but the note of major part note in part song
Highly it is positioned at a little scope in this interval, say, that the difference between most of note in a song is less.
Such as, in part song, the note height of major part note is positioned in interval [55,75].
