Abstract

The embodiments of the invention disclose an audio detection method and device, and a storage medium. The method comprises steps of obtaining a maximum value and a minimum value of each audio frame ina to-be-detected audio; determining a target audio frame, wherein the target audio frame is an audio frame in which the difference between the maximum value and the minimum values is smaller than a first threshold; if the target audio frame is not the mute data, obtaining an energy value whose frequency is less than a preset frequency in the target audio frame, and the proportion of the energy value in the total energy value of the target audio frame; and when the proportion is greater than the first preset energy threshold, determining that the target audio frame is an audio breakpoint. In this solution, the audio frame of the audio breakpoint can be accurately obtained by using the maximum value and the minimum value corresponding to each audio frame, the energy value wherein the frequency domain of the target audio frame is smaller than the preset frequency, and the total energy value of the target audio frame, which avoids the influence of subjective factors and improves the accuracy of audio detection.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an audio detection method, device and storage medium. Background technique [0002] With the development of the Internet and the rapid popularity of digital audio, for carriers such as vinyl, tapes, and CDs, during the transcription process of audio from analog signals to digital signals, due to various reasons such as carrier damage, the audio will be lost during recording. There are some flaws in the process. In addition, in the process of audio transmission through the Internet, errors may also occur, which introduces some defects. Among these defects, a breakpoint is one of them, and the breakpoint will cause the sound of the audio to be played intermittently, or the sound is lost. Therefore, the audio can be detected for a breakpoint so that the existing breakpoint can be repaired. [0003] In the prior art, when detecting breakpoints in audio, it is generally to a...
