摘要： A device for synchronizing an audio signal with a film comprising frames, wherein each frame comprises an imprinted time code, includes means for detecting the imprinted time code for the sequence of frames in order to obtain a detected sequence of time codes. Further, a time code generator is provided which is implemented to generate a sequence of synthesis time codes based on an initial value. A decoder is further provided to decode a time code of the detected sequence of time codes in order to provide the initial value for the time code generator. A detected time code and a corresponding synthesis time code are compared in order to then, when a phase deviation is found to be above a deviation threshold value, manipulate the synthesis time code for this frame in so far that it is changed with regard to its temporal length. This synthesis time code is then provided to an audio processing means which is implemented to provide 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. Thus, a flexible system is obtained, by which any number of audio players may be synchronized with the film, particularly as the audio players are provided with predefined synthesis time codes or manipulated synthesis time codes for synchronization purposes.
