Abstract

The embodiment of the invention discloses a method and apparatus for generating multimedia file. The method comprises: target original audio data corresponding to a target audio identifier are obtained and a target original spectral feature of the target original audio data is obtained; on the basis of a pre-trained audio extraction model, a target original-version-free singing spectral feature of target original-version-free singing audio data corresponding to the target audio identifier is calculated based on the target original spectral feature; according to the target original-version-free singing spectral feature, the target original-version-free singing audio data are generated; and fundamental frequency information of the target original-version-free singing audio data is extracted, a note value corresponding to the fundamental frequency information is obtained, and an audio numbered musical notation file corresponding to the target audio identifier is generated based on the note value. Therefore, an audio numbered musical notation file can be generated automatically; the accuracy of the audio numbered musical notation file is guaranteed; and the manufacturing efficiency of the audio numbered musical notation file is enhanced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a multimedia file generating method and equipment thereof. Background technique [0002] At present, a comprehensive entertainment client that integrates functions such as group chat, live video, karaoke, application games, and online video has been widely used in user terminals such as personal computers and mobile phones. In practical applications, users can sing songs through the entertainment client, and the server can evaluate and score the songs, realizing the interactive function of singing songs. [0003] In the prior art, the server end can pre-store the audio numbered notation file of the sung song. The audio numbered notation file describes the pitch trend of the original singer performing the song corresponding to the song. The user's sung songs are scored, and the audio numbered notation file can also be used to provide a visual note reference curve and to modify ...
