Abstract

The invention discloses an audio detection method, device and storage medium. The method includes: separating the audio signal of the audio to be tested to obtain the harmonic signal and the impact signal of the audio to be tested, and obtaining the impact signal Mel spectrum, then calculate the initial envelope of the shock signal according to the Mel spectrum, and obtain the autocorrelation velocity spectrogram of the initial envelope according to the initial envelope of the shock signal, and then according to the The second peak value in the autocorrelation velocity spectrogram is used to determine the rhythm intensity value of the audio to be tested. The embodiment of the present invention provides the rhythm intensity value of the audio clip by analyzing the regularity and intensity of strong impact points or strong impact points in the audio, so that the given rhythm intensity value is more in line with the user's auditory experience.

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...
