Pop sound detection method, device, terminal device and storage medium

Abstract

The present application discloses a POP sound detection method, device, terminal device and storage medium. The method includes: acquiring audio data to be detected; filtering the audio data to be detected, so as to filter some normal hopping signals to obtain filtered data; construct a detection signal based on the filtered data; compare the detection signal with a preset detection threshold; if the detection signal is greater than the preset detection threshold, it is determined that POP is detected sound. This solution can realize accurate detection of POP sounds in audio data, avoid missed judgments, and locate the location of POP sounds through real-time POP sound detection, providing an auxiliary reference for POP sound restoration, and the amount of calculation is small.

Description

technical field [0001] The present application relates to the field of multimedia technologies, and in particular, to a POP sound detection method, device, terminal device and storage medium. Background technique [0002] In the process of audio playback, POP sound is sometimes produced. POP sound is an abnormal broken sound. There are many reasons for producing POP sound, such as the influence of the external environment sound during recording, and the sound of pressing the stop button when the recording is stopped is recorded. Entering audio files, etc., these will result in the generation of POP sounds, which will affect the user's experience of playing audio. [0003] At present, when detecting a POP sound, the solution usually adopted is to compare the audio amplitude of the selected audio data with a threshold value. If the audio amplitude of the selected audio data is less than the threshold value, it indicates that the selected audio data may be There is POP tone da...

AI Technical Summary

Problems solved by technology

Because there are many types of reasons for the occurrence of POP sounds, this related technical solution cannot adapt to various types of POP sound detection

Moreover, only the amplitude of the audio is used to detect and judge the POP sound, which is only applicable to the scene where the sound volume suddenly increases. In the case of data jumps, the POP sound will also appear. The amplitude of the audio in this scene may not be high. at threshold

Therefore, the existing related schemes are relatively simple to detect POP sounds, and are prone to missed judgments
