[0026] See Figure 4 , which presents a flow chart of a pop-sound detection method according to an embodiment of the present invention. Such as Figure 4 As shown, the explosion sound detection method may include the following steps:

[0027]Step S401: Divide a section of audio source signal to be detected into multiple audio frames according to time sequence in a time domain. As an embodiment of the present invention, in the present invention, dividing a section of audio source signal to be detected into multiple audio frames may include: dividing the audio source signal to be detected into multiple audio frames in a sliding window manner, wherein, in dividing the audio In the frame time, an audio frame is divided according to a set translation length moved from a segment of the audio source signal to be detected, and the length of the divided audio frame is the set sliding window width. If the translation length is set to 5 milliseconds (ms) and the sliding window width i...

Abstract

The present invention proposes a popping sound detection method, comprising: for a sound source signal, obtaining a plurality of audio frames formed in time order in a time domain; sampling each audio frame; A sampling amplitude value of the sampling result is compared with a preset sampling amplitude value; according to the comparison result of each audio frame, it is confirmed that each audio frame belongs to a white noise part or a pop-like part; Adjacent white noise parts, adjacent popping-like parts and adjacent white noise parts appear in chronological order to confirm whether the sound source signal has popping sounds. When an audio frame and at least one adjacent audio frame are all white noise parts , then its corresponding audio frame belongs to adjacent white noise parts, and when an audio frame and at least one adjacent audio frame are both pop-like parts, then its corresponding audio frame belongs to adjacent pop-like parts.

Description

technical field [0001] The present application relates to the technical field of multimedia processing, and in particular to a method and device for detecting popping sounds. Background technique [0002] Due to the complexity of audio generation, processing, transmission, storage and other steps, some music has "distortion" in the audio, such as pop noise, glitches, breakpoints, etc. Popping sound is a relatively common distortion phenomenon. The so-called popping sound refers to a short pulse in the music waveform, which sounds like a "click", which will bring a poor experience to the listener. [0003] Therefore, in order to play the audio file smoothly on the electronic product, it is necessary to detect the part of the audio file where there is a popping sound, and then eliminate it. Usually, the detection of pops is mostly judged by the human ear, so many problems may occur, such as: the listener cannot do long-term and wide-ranging tests, the hearing sensitivity is n...
