Rhythm point detection method and device and electronic equipment

Abstract

The invention provides a rhythm point detection method and device and electronic equipment, and relates to the technical field of music analysis. The method comprises the steps: obtaining a to-be-detected audio signal, and generating an audio characteristic curve according to the to-be-detected audio signal; determining the wind type of the to-be-detected audio signal; determining a detection peakthreshold value and a detection frame width threshold value according to the curved wind type of the to-be-detected audio signal; and determining a rhythm point of the audio characteristic curve based on the peak threshold and the frame width threshold. The invention provides a rhythm point detection method and device and electronic equipment. The rhythm point of the audio characteristic curve can be determined based on the peak threshold and the frame width threshold. Therefore, the automatic detection process of rhythm points is realized; moreover, the audio characteristic curve is fused with the energy characteristic curve and the frequency spectrum characteristic curve, so that the rhythm point detection is more accurate, and the peak threshold and the frame width threshold are determined according to the music style, so that the rhythm point detection can be performed on audio signals of different styles, and the music rhythm detection requirement is effectively met.

Description

technical field [0001] The invention relates to the technical field of music analysis, in particular to a rhythm point detection method, device and electronic equipment. Background technique [0002] The current dance culture is developing in a diversified direction, and more and more people are learning and choreographing dance, providing us with high-quality dance art. With the development of the Internet, in the digital field, using computer software to drive 3D models to arrange beautiful dances is also a hot spot nowadays. [0003] Usually, when using computer software for choreography, the user usually drives the 3D model to complete the dance action by using the K action sequence in several consecutive animation frames according to the rhythm of the music, or choose some public action sequences to apply directly, regardless of Either way, the user's selection of the music rhythm point is based on experience, and the process is time-consuming, labor-intensive, and ina...
