Audio data processing method, device and computer storage medium

Abstract

An audio data processing method, characterized by comprising: acquiring dry audio data, calculating fundamental frequency reliability corresponding to the dry audio data, and determining a fundamental frequency of the dry audio data according to the fundamental frequency reliability (S101); acquiring a probability distribution of a non-zero fundamental frequency of the dry audio data, and determining a dominant fundamental frequency of the dry audio data according to the probability distribution (S102); selecting, according to the dominant fundamental frequency, target audio data from the dry audio data (S103); determining, according to the fundamental frequency of the target audio data, target harmonic energy corresponding to the target audio data (S104); determining first timbre quality data of the dry audio data according to the target harmonic energy, the first timbre quality data being used to measure the timbre of the dry audio data (S105). The present method objectively and accurately scores the timbre of dry audio data.

Description

technical field [0001] The invention relates to multimedia information technology, in particular to an audio data processing method, device and computer storage medium. Background technique [0002] Timbre, also known as timbre, is the characteristic of the sound felt by the auditory sense. Different people have different timbres. The round and beautiful timbre is pleasing to the eye, while the thin timbre sounds "astringent". In the prior art, the quality of the singer's timbre is judged through subjective feelings. However, these subjective feelings vary from person to person and are difficult to quantify. Therefore, it is impossible to make an objective and accurate judgment on the quality of the timbre, and it is also impossible to judge the quality of the singer's timbre. Make a rating. Contents of the invention [0003] Embodiments of the present invention provide an audio data processing method, device and computer storage medium, which can objectively and accura...
