In a system and method for dynamically synchronizing a digital soundtrack with a moving picture in motion picture media, the system includes a device for presenting the motion picture media, wherein the motion picture media further includes an analog soundtrack. The digital soundtrack further includes a variable delay to compensate for the distance between a frame in the moving picture and a portion of the digital soundtrack corresponding thereto. A synchronizing device is correlated to a digital soundtrack pickup and an analog soundtrack picture in a feedback loop. A processor in the synchronizing device is adapted to process the digital soundtrack and the analog soundtrack to generate a control signal based on the difference between the location of a transient reference in the analog soundtrack and the same transient in the digital soundtrack, and to use the control system to adjust the variable delay in the digital soundtrack for synchronization thereof. |
