Abstract

The invention relates to an audio processing method and device. The audio processing method comprises the following steps: acquiring a Midi pitch sequence of a digital interface of a reference musical instrument; determining the offset of each frame pitch in the human voice audio signal based on the reference Midi pitch sequence, and obtaining an offset sequence of the human voice audio signal; carrying out framing shift on the human voice audio signal based on the offset sequence to obtain a human voice audio shift signal; and mixing the human voice audio signal and the human voice audio shift signal to obtain the harmony of the human voice audio signal. According to the audio processing method and device disclosed by the invention, unharmonious tones can be prevented from being brought, and an intelligent harmony effect is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of audio and video. More specifically, the present disclosure relates to an audio processing method and device. Background technique [0002] In the online karaoke system, you can record singing voices according to the accompaniment, and then pass the vocals through some effects such as EQ, compression, reverb, and volume balance, and then mix the processed vocals with the accompaniment. With the increase of users, people also have more demands for K song sound effects. Traditional sound effects such as reverb and EQ can no longer meet the requirements of music lovers for karaoke effects, so more and more sound effects have been introduced, and one of the important effects is intelligent harmony. It is used to simulate the real effect of adding accompaniment to the original sound, which can achieve the effect of enriching the human voice and emphasizing the singing emotion. [0003] K song intell...
