Abstract

The invention discloses an audio detection method and device and a storage medium. The audio detection method comprises the following steps that audio signal separation is carried out on audio to be detected so as to obtain a harmonic signal and an impact signal of the audio to be detected, and a Mel frequency spectrum of the impact signal is obtained; an initial envelope of the impact signal is calculated according to the Mel frequency spectrum; an autocorrelation velocity spectrum of the initial envelope is obtained according to the initial envelope of the impact signal; and a rhythm intensity value of the audio to be detected is determined according to a sub-peak peak value in the autocorrelation velocity spectrum. According to the audio detection method and device, by analyzing the regularity and intensity of occurrence of strong impact points or strong impact points in the audio, the rhythm intensity value of an audio segment is given, so that the rhythm intensity value is more inline with the auditory feeling of a user.

Description

technical field [0001] Embodiments of the present invention relate to the field of audio processing, and in particular to an audio detection method, device and storage medium. Background technique [0002] The sense of rhythm, also known as the sense of rhythm, refers to a subjective feeling of human beings to the rhythm of music. Music with a strong sense of rhythm has clear beats and usually has rich and regular percussion content. Rhythm is a pattern composed of repetitive elements such as rhythm, speed, strength, melody, and harmony in music. [0003] The rhythm sense of music has a wide range of applications, such as music recommendation, emotion classification, etc., but the rhythm sense is a relatively subjective feeling, which lacks a reasonable numerical description. Contents of the invention [0004] Embodiments of the present invention provide an audio detection method, device, and storage medium, capable of measuring the rhythmic strength of audio with objecti...
