Abstract

The invention discloses a music identifying method and system. The method comprises steps of acquiring a to-be-identified music clip, extracting a mel-frequency cepstrum coefficient of each frame of the to-be-identified music clip, a mel-frequency cepstrum coefficient first difference, a linear prediction cepstrum coefficient and a sensing linear prediction coefficient, forming an audio feature vector according to the above coefficients of the audio, combing feature vectors of each frame audio to achieve a feature matrix of the to-be-identified music clip, comparing the feature matrix of the to-be-identified music clip and a feature matrix of a sampling music in a music library to achieve a maximum-similarity feature matrix, acquiring music information of a maximum sampling music feature matrix, and outputting the music information. The maximum-similarity feature matrix belongs to a sampling music having the maximum similarity to the to-be-identified music. The music identifying method and system have great noise resisting property and great identifying efficiency and ideal identifying effect.

Description

technical field [0001] The invention relates to the field of music recognition, in particular to a music recognition method and system. Background technique [0002] With the vigorous development of science and technology, especially the emergence and rapid development of computer technology, Sound and Music Computing (SMC) has become an emerging interdisciplinary subject, which is mainly understood, simulated and generated through computational methods. sound and music. [0003] With the maturity and development of various technologies, people can obtain music through various channels. Among them, the network is the most convenient and fastest access channel. This has directly led to the explosive growth of music on the Internet, and people are also accustomed to searching and downloading music through the Internet. However, not all music disseminated through the Internet has complete music information labels. On the one hand, it has caused certain difficulties for manag...
