A synchronization method and system for decoding digital audio data stream. A data stream has synchronization words successively spaced with data payloads. A detector detects one of the synchronization words. A header sensor detects a frame header associated with a detected synchronization word. A location estimator estimates a search region in the data stream according to a detected header. If the search region is estimated, the word detector directly searches the search region to locate one of the synchronization words. A decision maker determines whether the system is synchronized with the data stream after the word detector locates one of the synchronization words.
