Abstract :
Tempo detection is basic in automatic music processing and in many multimedia applications. This paper presents the implementation algorithm and design for tempo tracking from polyphonic music signals on non-PC system. The method of crossover switching is proposed and the concept of variable threshold for energy flux operation is defined. This system consists of the pre-processing part and main processing part. The preprocessing part is based on an efficient filter-bank separation with logarithmic audio theory. And main processor part is based on energy flux sum or production. This system is evaluated using 100 sample songs from several musical genres. The results rate is about 85%.
