The present invention discloses a detection method, device and storage medium for an audio burst sound at the beginning. The method includes: obtaining training samples, and preprocessing the training samples to obtain multiple audio sub-segments of different scales, and then combining the multiple Input audio sub-segments of different scales into the first reference model for feature extraction training to extract multiple feature maps of different scales, and then input multiple feature maps of different scales into the second reference model for feature fusion training to obtain Feature fusion parameters, and generate a detection model based on multiple feature maps of different scales and feature fusion parameters, where the detection model includes the first reference model and the second reference model after training, and finally based on the detection model, perform audio crackling at the beginning of the audio to be tested Detection, which improves the accuracy of audio crackle detection at the beginning, and can effectively detect audio crackle at the beginning.
Description
technical field [0001] Embodiments of the present invention relate to the field of audio processing, in particular to the technical field of mobile devices, and in particular to a method, device and storage medium for detecting a crackling sound at the beginning of audio. Background technique [0002] An opening pop is a common audio artifact, usually caused by an encoder, but can also be caused by inadvertent recording, such as accidental rubbing. The bursting sound at the beginning will affect the user's listening experience. In addition, the opening detonation has the characteristics of various forms and positions, and the normal sound effect of some audio has similar characteristics to the opening detonation, which makes the detection of the initial detonation difficult and the detection accuracy is low. Contents of the invention [0003] Embodiments of the present invention provide a method, device, and storage medium for detecting an audio initial pop, which improve...
