Abstract

The location of accented beats of a music track is determined. A signal is extracted from the music track. The signal is demultiplexed across a number of channels such that each consecutive channel contains a consecutive portion of the signal, each portion of the signal corresponding a consecutive beat period, the number of channels corresponding to the meter of the music track. The content of each channel is analysed to determine which channel has different signal properties. The channel having the different signal properties is the channel containing the accented beats.
