Abstract

The invention relates to a music rhythm detection method and a music rhythm detection device. The music rhythm detection method comprises the steps of acquiring an audio signal of a piece of detected music, calculating a cross-correlation function between the audio signal of the detected music and audio signals of preset music rhythm models, acquiring the number of the preset music rhythm models included in the detected music according to the type of the detected music and the number of times that each peak position of a cross-correlation function curve appears in the detected music, and comparing the number of the preset music rhythm models included in the detected music and preset rhythm information to determine the rhythm of the detected music. The speed of music rhythm detection is improved, and higher detection accuracy can be achieved.

Description

technical field [0001] The invention relates to the technical field of music processing, in particular to a music rhythm detection method and a detection device. Background technique [0002] With the continuous development of Internet technology, more and more users can access digital music more conveniently and quickly. The problem people face is no longer the lack of media content, but how to classify music, for example, by detecting music rhythm And classify the music to find the information you need in the vast music world. In the past, the detection of music rhythm was mainly done manually. When faced with a large amount of music on the Internet, manual classification is not enough to complete such a huge workload. At this time, it is necessary to use computers and artificial intelligence to replace manual classification to realize automatic detection of music rhythm. . [0003] At present, the automatic detection of music rhythm mainly includes the following methods...
