Cumulative Scores Based for Real-Time Music Beat Detection System

Beat detection is a standard stage that is used to overcome other problems in Music Information Retrieval (MIR). The algorithm for beat detection has become increasingly complicated in recent years. The method used in this research is an algorithm that has been simplified from previous work. By using the spectral flux method to get the Onset Detection Function (ODF) signal, then estimate the tempo. ODF signal and estimated tempo are used as input for cumulative score to get the right beat location. This system results in an average of 80% simulation on music that has a constant or almost constant tempo, this is an excellent result where only using a simple algorithm. To check the effectiveness and reliability, the system will be tested with actuator movements.
