| Abstract: | In order to get message of music tempo, a research analyze sampling signal in AR spectrum by a method extracting whole number from data that decreased data capacity after analyzing energy signal and making a deeision of fluctuating of energy signal. Moreover it can find music tempo from frequency domain and make a right decision of music tempo. |
