A method, apparatus and system for synchronizing audiovisual content with inertial outputs for content reproduced on a mobile content device include, in response to a vibration of the mobile content device, receiving a recorded audio signal and a corresponding recorded inertial signal generated by the vibration. The recorded signals are each processed to determine a timestamp for a corresponding peak in each of the recorded signals. A time distance between the timestamp of the recorded audio signal and the timestamp of the recorded inertial signal is determine and inertial signals for content reproduced on the mobile content device are shifted by an amount of time equal to the determined time distance between the timestamp of the recorded audio signal and the timestamp of the recorded inertial signal.
