Abstract

In this report, a music extraction technique, which can be applied on consumer electric products, is proposed to detect when there is music in the FM radio broadcasting by using the analysis of power change and GMM. Usually, when music is broadcasted, the voice power is less, compared to the time of DJ's talk. According to the factor, the candidates(changing points) of the boundaries between music broadcast and DJ's talk are firstly detected; and then classification is applied to eliminate the false positives by GMM. A section of time is considered to be the music broadcasting if the duration between two consecutive recognized boundaries is longer than a threshold. Two definitions, music extraction accuracy and extraction rate of music, are defined for the evaluation of our proposed method according to the viewpoint of usability.
