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.
