Abstract

The invention discloses an audio beat detection method and device and a storage medium. The audio beat method comprises the following steps that a training sample is obtained, characteristic extracting is carried out on the training sample to extract audio characteristics of the training sample, the audio characteristics of the training sample is input into a reference model for learning and training to obtain optimized parameters of the reference model after training, and a detection model is generated according to the optimized parameters; and then, audio beat detection is carried out on audio to be detected based on the detection model to obtain a beat per minute (BPM) value of the audio to be detected and confidence corresponding to the BPM value, so that the accuracy of audio beat detection is improved, and the running time in the detection process is shortened.

Description

technical field [0001] Embodiments of the present invention relate to the field of audio processing, and in particular to an audio tempo detection method, device and storage medium. Background technique [0002] BPM (Beat Per Minute) is a basic attribute of music and a quantitative indicator of music speed. Music with a higher BPM feels faster, and vice versa. BPM has various practical applications, such as recommender systems, fitness music, etc. [0003] At present, the estimation of BPM is a research hotspot. There are two main categories, one is BPM estimation based on onset, and the other is BPM estimation based on the signal itself. Many open source codes (such as librosa, Madmom, etc.) can be used for BPM estimation, but the accuracy rate is not high, and the calculation speed is very slow. Contents of the invention [0004] Embodiments of the present invention provide an audio tempo detection method, device, and storage medium, which can improve the accuracy of ...
