Abstract:
1. A device for synchronizing an audio signal present in discrete samples with a film comprising a sequence of frames that may be played with a frame frequency, wherein each frame comprises an imprinted time code indicating a position of the frame in the sequence of frames, and wherein a predetermined number of discrete samples of the audio signal is associated with a frame, comprising: a detector for detecting the imprinted time codes for the sequence of frames in order to obtain a detected sequence of time codes; a time code generator which is implemented to generate a sequence of synthesis time codes based on an initial value; a decoder for decoding a time code of the detected sequence of time codes in order to provide the initial value for the time code generator; a comparator for comparing the sequence of synthesis time codes with the detected sequence of time codes; a time code manipulator for changing a time length of a synthesis time code of the sequence of synthesis time codes in order to obtain a manipulated synthesis time code when the comparator determines a phase deviation between a time code of the detected sequence of times codes and a synthesis time code of the sequence of synthesis time codes which exceeds a predetermined deviation threshold value with regard to its amount; and an audio processor for a time-controlled provisioning of the predetermined number of discrete samples of the audio signal associated with a frame when the audio processor detects a synthesis time code or a manipulated synthesis time code identifying the frame.
