Time domain note average energy based music onset detection

A novel time domain strategy is proposed for the detection of the onset of musical notes based on the changing energy level. By calculating the note average energy (NAE), the proposed method is insensitive to both the dynamic range of the energy levels in a piece and whether or notthe piece is monophonic or polyphonic. More importantly, the new strategy tackles the thorny ‘threshold’ problem that is always being avoided unsuccessfully. The detection performance of the new method is illustrated by its performance over a range of music pieces played on different instruments
