The embodiment of the present application provides a music label prediction method and related equipment, wherein the method includes loading the target music according to the target sampling rate, the target music corresponds to multiple loading sampling rates, and the target sampling rate is one of the multiple loading sampling rates ;After the target audio data is obtained by loading the target music, dynamically calculate the Fourier transform parameters corresponding to the target audio data according to the target sampling rate; based on the calculated Fourier transform parameters, perform variable sampling discrete Fourier transform on the target audio data , to obtain the target spectrogram; predict the category of the target music according to the target spectrogram, and obtain the category prediction label of the target music. The application has high applicability, can improve the processing efficiency of label prediction, and save the cost required for label prediction.
Description
technical field [0001] The present application relates to the technical field of audio processing, in particular to a music label prediction method and related equipment. Background technique [0002] In recent years, with the rapid development of the digital music industry, users can listen to a large amount of music through various music playback platforms. The music playback platform can pre-set category labels such as language and style for music, so that users can use these category labels when searching for music to find resources that meet individual needs. At present, when predicting the category labels of different music, it is usually necessary to perform data interpolation processing on different music according to a fixed sampling rate, so as to unify the different music into sampled data in a standard format, and then based on the sampled data in the standard format for each Music for category label prediction. However, the data interpolation process consumes ...
