Music score generation method and device based on audio file identification and terminal equipment

Abstract

The invention discloses a music score generation method and device based on audio file identification and terminal equipment. The music score generation method comprises the following steps: acquiringan audio file to be converted and converting the audio file to be converted into a spectrogram to be identified; performing feature extraction on the spectrogram to be identified according to the spatial density distribution features of the points in the spectrogram to be identified to obtain a feature vector to be converted; and inputting the to-be-converted feature vector into a preset music score conversion model, so that the music score conversion model generates a music score corresponding to the to-be-converted audio file according to the to-be-converted feature vector. By implementingthe embodiment of the invention, the corresponding music score can be automatically generated, and the difficulty of obtaining the music score by a user is reduced.

Description
