Abstract

The present invention relates to the field of audio signal processing, and in particular to a method for detecting main beat points in music, a computer storage medium, and a terminal. The method includes: acquiring a music beat point sequence; calculating every two adjacent beat points in the beat point sequence The distance value of the beat point; count the number of occurrences of the same distance value, and determine the corresponding distance value according to the number of times; obtain a beat point from the beat point sequence, and count other beat points in the beat point sequence The position falls into the acquired beat point plus the number of positions of an integer multiple of the beat period; determine whether the number meets the conditions, and if so, confirm the acquired beat point and other beat points that fall into the position of an integer multiple of the beat period The key point of the music. The invention accurately represents the rhythm information of the music by detecting the main tempo point of the music, so as to further process the music by utilizing the rhythm information of the music.

Description

technical field [0001] The invention relates to the field of audio signal processing, in particular to a method for detecting a master beat point in music, a computer storage medium, and a terminal. Background technique [0002] Different rhythms of music can express different musical moods. With the continuous development of Internet technology and audio and image processing technologies, users will add music to improve the audiovisual experience of videos when recording videos. However, in the prior art, music It is simply added to the video, but it is not well integrated with the video. The reason is that the beat of the music cannot be detected accurately. The existing audio detection methods focus on the detection of a single beat point. In general, whether it is using the peak value of the time domain signal envelope or the difference and difference of the frequency domain signal change to detect the beat point, and the music beat point is mainly led by a specific inst...
