Method and device for generating musical scores

Abstract

The invention discloses a music score generating method and a music score generating device, belonging to the technical field of terminals. The music score generating method comprises the following steps: acquiring audio signals of a target multi-media file; according to the frequency of the audio signal of each note moment, determining the pitch of the audio signal of each note moment; forming a pitch sequence by adopting the pitches of the audio signals of the note moments, and determining a note sequence of the target multi-media file according to the preset intervals among the pitch sequence and the note moments; dividing the note sequence into a plurality of note subsequences, and acquiring the rhythm of each note subsequence; and forming the music score of the target multi-media file by adopting the note subsequences and the rhythms of the note subsequences. According to the music score generating method and the music score generating device, through the frequencies of the audio signals of the note moments, the pitches, note sequence and the rhythms are obtained, the music score of the target multi-media file is determined, and thus the accuracy in generating the music score is improved.

Description

Technical field [0001] The present invention relates to the technical field of terminals, in particular to a method and device for generating music scores. Background technique [0002] With the development of terminal technology, the functions supported by the terminal become more and more powerful. For example, the terminal can support music software; the terminal can not only play songs through music software, but also generate music scores through music software; while playing songs To display the music score of the song on the current playback interface. [0003] Currently, professionals usually listen to the target song repeatedly, and identify each note of the target song through the melody of the target song, thereby obtaining the score of the target song. [0004] In the process of implementing the present invention, the inventor found that the prior art has at least the following problems: [0005] Professionals need to repeatedly listen to the target song to recognize the ...

AI Technical Summary

Problems solved by technology

[0005] Professionals need to listen to the target song repeatedly before they can recognize the notes, which leads to the low efficiency of the above-mentioned generation of music scores; and, due to the influence of factors such as professional staff's experience in reading music scores and technical knowledge, the accuracy of the above-mentioned method to generate music scores is poor.
