The embodiment of the invention provides a sound correction method and device, equipment and a storage medium, and is applied to the technical field of audio processing. Human voice signal correction can be carried out under the condition that personal characteristics of a user are ensured. The method specifically comprises the following steps of: acquiring a song audio voice signal and standard music score data corresponding to the song audio voice signal, the standard music score data comprising at least one standard note and a pitch value of each standard note; determining a note corresponding relation and an initial pitch value sequence of the song audio human voice signal, the note corresponding relation comprising a corresponding relation between each note in the song audio human voice signal and a standard note, and the initial pitch value sequence comprising a pitch value of each frame of sub human voice signal in the song audio human voice signal; according to the note corresponding relation and the pitch value of the standard note, adjusting the pitch value in the initial pitch value sequence to obtain a target pitch value sequence; and correcting the song audio human voice signal according to the initial pitch value sequence and the target pitch value sequence.
Description
technical field [0001] The present disclosure relates to the technical field of audio processing, and in particular, to a sound modification method, device, equipment and storage medium. Background technique [0002] In the process of singing, because each user has a 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 human voice signal has undergone multiple conversions, and conversion 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 user...
