Problems solved by technology

"Beginning pop" means that there is a short pulse at the beginning of the music waveform, which sounds like a "click". This harsh and unnatural sound will bring a poor user experience to the listener
In a statistical case of a song library, the proportion of audio with crackling sounds at the beginning reaches 10%. Due to the presence of crackling sounds, the audio quality is poor

Abstract

The embodiments of the invention disclose an audio popping detection method and device and a storage medium. A to-be-detected audio signal can be obtained when the audio signal is subjected to popping detection, the audio signal is divided into a plurality of frame signals, then the short-time energy difference between every two adjacent frame signals is calculated, then frame signals satisfying the preset condition interval are obtained according to the short-term energy differences, sudden change audio signals are obtained, then the frequency spectrum flatness of the sudden change audio signals is calculated, and if the frequency spectrum flatness is greater than a preset flatness value, the popping of the audio signals is determined. According to the scheme, whether the audio signals have the popping or not can be accurately detected.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an audio pop detection method, device and storage medium. Background technique [0002] With the continuous development of Internet technology, there are a large number of various audio files on the Internet, such as various types of audio files such as music / speech / storytelling / chat. As the audio goes through a series of complex steps such as recording, processing, transmission, and storage, there may be "distortion" phenomena, such as initial pops, glitches, and breakpoints. Crackling at the beginning is a relatively common distortion phenomenon. "Beginning pop" means that there is a short pulse at the beginning of the music waveform, which sounds like a "click". This harsh and unnatural sound will bring a poor user experience to the listener. In a statistical case of a song library, the proportion of audio with crackling sounds at the beginning reaches 1...
