Accompaniment method for actively following music signals and related equipment

Abstract

The embodiment of the invention discloses an accompaniment method for actively following music signals and related equipment. The accompaniment method comprises the following steps that: first audio data of a performer in the performance process of a target track are acquired; an observation sequence is determined according to the first audio data and music scores corresponding to the target track, wherein the observation sequence is a corresponding sequence of each note in the first audio data and a performance moment of each note; a prediction sequence is determined according to the observation sequence and the music scores, wherein the prediction sequence is a corresponding sequence of each note of the first audio data and the predicted performance moments; and according to the observation sequence and the prediction sequence, the performance moment of the musical note of the next performance of the performer is predicted, and according to the corresponding relationship between the music scores and accompaniment audios, accompaniment audio data corresponding to the musical note of the next performance is controlled to be played at the predicted performance moment. According to the method, the occurrence time of the next note to be performed of the performer can be accurately predicted, the accompaniment is automatically matched with the performance so as to be played, and the interaction effect between the accompaniment and the performance is improved.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an accompaniment method for actively following a music signal and related equipment. Background technique [0002] With the growing maturity of the music market and the popularization of music education, more and more scenes need to use automatic accompaniment to match the accompaniment with people's performance to achieve better interaction and bring better music enjoyment and experience . Typical application scenarios that require automatic accompaniment include: concerts, karaoke, various musical instrument solos, etc. [0003] The existing accompaniment playback scheme is as follows: since the accompaniment is in one-to-one correspondence with the score, people perform / sing according to the score, and first match the audio signal of the performance / sing with the score to determine the current performance / singing position, and then play and sing. The accompaniment a...

AI Technical Summary

Problems solved by technology

However, in the above solution, the accompaniment has the defect of delayed playback, and the accompaniment cannot match the audio signal in real time, resulting in poor automatic accompaniment playback and poor user experience

Moreover, the accompaniment audio is prepared in advance, fixed, and unmodifiable, which leads to the fact that people can only compare their performance / singing speed, pause, speed change, etc. with the accompaniment audio during the performance process Matching, which seriously hinders the performer's personalized musical expression of the track and reduces the beauty of the music
