Audio detecting method and device, electronic equipment and storage medium

Abstract

The invention discloses an audio detecting method and device, electronic equipment and a storage medium, and belongs to the technical field of digital audio processing. On the basis of an energy valueof an audio frame, a zero crossing rate, a weight frequency spectrum value and a frequency spectrum flatness in an audio file, linear related coefficients between the audio frame and the previous audio frame and other characteristic parameters, whether or not burst white noise exists in the audio frame is detected, when it is determined that the energy value of the audio frame is larger than a first threshold value, the zero crossing rate is larger than a second threshold value, the weight frequency spectrum value is larger than a third threshold value, the frequency spectrum flatness is larger than a fourth threshold value, and the linear related coefficients between the audio frame and the previous audio frame are smaller than a fifth threshold value, it can be determined that burst white noise existing in the audio frame is detected, on the basis of the audio detecting method, whether or not an audio file of any type has burst white noise can be detected, on the basis of multiple characteristic parameters, the accuracy of the detecting result is higher, and the robustness of the detecting method is higher.

Description

technical field [0001] The invention relates to the technical field of digital audio processing, in particular to an audio detection method, device, electronic equipment and storage medium. Background technique [0002] With the development of the Internet, people's demand for audio is getting higher and higher. Any process of audio recording, processing, transmission, and storage may cause the audio to be modified or damaged, resulting in some defects in the audio, for example, The defect may be a burst of white noise. The sudden white noise will cause the user to hear noisy noise when playing the audio. Therefore, the audio can be detected so as to replace, repair or discard the audio frame with the sudden white noise. [0003] At present, the commonly used audio detection method is: for each audio frame in an audio file, the three characteristic parameters of energy, zero-crossing rate and weight spectrum value of each audio frame are obtained in turn. When the energy of...
