Audio correction method and device

Abstract

The embodiments of the invention provide an audio correction method and device. The method comprises: acquiring first audio data; acquiring a first pitch contour which is a pitch contour of the first audio data; sequentially performing scale correction and tone correction on the first pitch contour according to a second pitch contour to obtain a corrected first pitch contour, wherein the second pitch contour is a pitch contour of second audio data corresponding to the first audio data; converting the corrected first pitch contour into audio signals to obtain corrected first audio data. Taking a song as an example, the method and the device enable the corrected pitch contour of the song sung by a user to be consistent with the trend of the pitch contour of the original song, and the rise and fall of the pitch contour of the song sung by the user are closer to those of the original song over correction, so that the rhythm and listening feeling of the song sung by the user are greatly improved, and the correction effect on audio data of songs and the like is improved.

Description

technical field [0001] The invention relates to audio data processing technology, in particular to an audio correction method and device. Background technique [0002] In work and life, people sometimes encounter scenes that require recording audio, for example, the audio can be music played, or songs sung, and so on. Taking songs as an example, with the rapid development of the mobile Internet, various singing apps (application software) are gradually emerging. For ordinary users, sharing their own recorded songs on social networking sites has become a new way of socializing. However, due to the lack of professional singing training, ordinary users are often unable to sing the entire song well. For example, there may be problems such as singing the wrong tune and not keeping up with the rhythm. These problems will affect the listening experience of the recorded songs. Therefore, before the recorded song is released, it has become an urgent need for users to modify the reco...

Problems solved by technology

[0004] Yet the inventor finds in the process of realizing the present invention, if the same or similar parts of the lyrics are not sung well, then this correction cannot be completed, and even if there is a better singing of the same or similar parts of the lyrics can be used to replace For other parts, the existing method does not consider the user's sense of hearing when correcting the user's singing, because even in the same or similar lyrics, the pitch or rhythm of the song may be different. If the existing technology This direct replacement method is likely to cause the corrected song to sound strange, that is, the sense of hearing and rhythm is poor

It can be seen that the existing technology cannot perform good corrections on audio such as songs
