ABSTRACT:
A device for synchronizing an audio signal with a film comprising frames having imprinted time codes. A detector detects the imprinted time code for the sequence of frames to obtain a detected sequence of time codes. A time code generator generates a sequence of synthesis time codes based on an initial value. A decoder decodes a time code of the detected sequence of time codes obtain the initial value. A comparator compares a detected time code and a corresponding synthesis time code and, when a phase deviation is found to be above a deviation threshold value, a time code manipulator manipulates the synthesis time code for this frame in so far that it is changed with regard to its temporal length. An audio processor provides the samples of the audio signal associated with this frame in a time-controlled way in response to a detection of the synthesis time code for a frame.
