The invention discloses an audio data processing method, a device thereof and a storage medium. The method comprises: obtaining training samples, and then extracting a plurality of pieces of feature information from the training sample, wherein the plurality of pieces of feature information include spectral height features, the distinctive features of pure music and human voice, the audio beginning feature corresponding to the first preset time length and the audio ending feature corresponding to the second preset time length, Then the feature information is input into the neural network for feature fusion training to obtain the trained feature fusion parameters, and the audio classification model is generated according to the feature fusion parameters. if the test audio is received, classifying the test audio by the audio classification model. The embodiment of the invention obtains the feature fusion parameters combining the features of multiple aspects through the feature fusion ofmultiple feature information, and reintegrates the feature fusion parameters into the audio classification model for audio classification, thereby improving the accuracy of audio classification and effectively distinguishing the live audio from the audio of the recording studio.
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 an audio data processing method, device, and storage medium. Background technique [0002] Field-studio audio classification is a challenge encountered in music library management. For a given audio, we need to judge whether it comes from field recording or recording studio, so as to provide it to different users. Among them, live (Live) refers to music recording in non-professional environments such as concerts and public concerts, and studio (Studio) refers to music recording in professional recording environments. In the process of realizing the present invention, the inventors found that the prior art generally has the problem that non-artificial distinction between live-studio audio is easy to confuse. Therefore, it is necessary to propose a new audio data processing method. Contents of the i...
