Abstract

Embodiments of the present disclosure provide a sound modification method, device, equipment and storage medium, which are used in the technical field of audio processing. It can correct the human voice signal while ensuring the user's personal characteristics. It specifically includes: obtaining the song audio human voice signal and the standard music score data corresponding to the song audio human voice signal; the standard music score data includes at least one standard note and the pitch value of each standard note; determining the corresponding relationship between the notes and the song audio human voice signal The initial pitch value sequence; the note correspondence includes the correspondence between each note in the song audio vocal signal and the standard note; the initial pitch value sequence includes the pitch of each frame of the sub-voice signal in the song audio vocal signal High value; according to the note correspondence and the pitch value of the standard note, adjust the pitch value in the initial pitch value sequence to obtain the target pitch value sequence; modify the song according to the initial pitch value sequence and the target pitch value sequence Audio vocal signal.

Description

technical field [0001] The present disclosure relates to the technical field of audio processing, and in particular, to a sound modification method, apparatus, device, and storage medium. Background technique [0002] In the process of singing, because each user has different perception of music and melody, the problem of out-of-tune often occurs. [0003] In the related art, the out-of-tune problem is solved by automatic tuning. Automatic tuning refers to converting the user's vocal signal into a digital score, correcting the digital score according to the difference between the pitch value of each note in the digital score and the pitch value of each note in the standard score data, and finally correcting the human voice. Signal. During the correction process, the vocal signal has undergone multiple transformations, and transformation errors will inevitably occur. At the same time, the pitch value of each note in the standard score data is a constant value, while the us...
