Abstract
Disclosed is an audio device that adjusts the cadence of played songs. A user sensor determines cadence data based on movement of the user. A desired cadence is determined based on the cadence data received from the sensor. The cadence of songs is determined by low pass filtering digital representations of the songs and determining the period (T) of the back beat of the songs. An adjustment of the period (T) of the songs is then determined such that the adjustment of the period (T) of the songs results in the songs having the desired cadence. The period (T) of the back beat of the subsequent songs are then adjusted.
