Abstract

The invention relates to an audio processing method and device. The audio processing method comprises the following steps: based on tonality information and mode information of an original audio corresponding to a recorded audio, obtaining a pitch of a scale corresponding to the original audio; for each signal frame of a human voice signal in the recorded audio, executing the following operations: determining a reference pitch of the current signal frame based on a pitch of a musical scale corresponding to the original audio; adjusting the pitch corresponding to the current signal frame based on the reference pitch of the current signal frame to obtain a target pitch of the current signal frame; and processing the current signal frame based on the target pitch.

Description

technical field [0001] The present disclosure relates to the field of audio and video processing, in particular to an audio processing method and device. Background technique [0002] Tone correction mainly refers to correcting the pitch of the human voice in the collected audio, so that the processed human voice is more accurate than the unprocessed human voice, and at the same time, it can also cover up some singing defects such as broken sound and unstable breath. ,off tune. Usually, in order to obtain accurate vocal pitch, sound mixers can use some audio plug-ins such as wave-tune and Melodyne to manually correct the vocal pitch to achieve the above purpose. Sound correction has become a concern of audio workers. [0003] At present, automatic tuning strongly relies on midi reference information. However, not every recorded audio has corresponding midi reference information. For example, an adapted song does not have corresponding midi reference information. At this ti...
