Problems solved by technology
[0003] The current method for determining the drum waveform is fixed-length selection, that is, selecting the drum waveform with a candidate frame of a specified length on the source song. The lengths are not exactly the same, which may cause the intercepted drum waveform to destroy the integrity of the waveform, that is, some drum waveforms are not intercepted; or the audio segment of the non-drum waveform is intercepted
Therefore, the fixed-length selection method cannot accurately select the drum waveform

The embodiment of the invention discloses a drumbeat waveform determination method and device and a computer storage medium and aims to determine an audio segment corresponding to a drumbeat waveformmore accurately. The method provided by the embodiment of the invention comprises the following steps of: determining a candidate box of a target drumbeat waveform, determining an audio frame with thehighest energy value in k audio frames as a reference point; and taking the reference point as a reference, further determining an audio frame of which the energy value is less than a first thresholdvalue a starting frame of the drumbeat waveform and an audio frame of which the energy value is less than a second threshold value as a termination frame of the drumbeat waveform, thereby determiningthe drumbeat waveform. According to the drumbeat point waveform determination method and device and computer storage medium of the embodiment of the invention, the drumhead waveform is determined based on the energy values of the audio frames in the candidate box. Compared with the fixed-length selection of the drumhead waveform, the determination standard and the determination method of the drumhead waveform are added, so that the selection result of the drumhead waveform is more accurate.
Description
technical field [0001] The embodiments of the present application relate to the field of data processing, and in particular to a method, device and computer storage medium for determining a drum beat waveform. Background technique [0002] The drum beat waveform refers to the waveform of the local short audio corresponding to the drum beat in the music song. The drum beat is also the rebeat in the music song. It is the audio segment with a large amplitude in the music song. The length of the drum beat waveform is usually 100-500ms. The drum waveforms obtained by different types of drums are different from each other. Therefore, the type of drum can be determined by identifying the drum waveform and used as training data for the drum classification model. The drum classification model is also a network model for identifying the type of drum. . [0003] The current method for determining the drum waveform is fixed-length selection, that is, selecting the drum waveform with a ...
