| 20080219637 | APPARATUS AND METHOD FOR SYNCHRONIZING A SECONDARY AUDIO TRACK TO THE AUDIO TRACK OF A VIDEO SOURCE - Synchronizes a secondary audio track to a video. Analyzes the audio track of a video using audio frequency analysis or spectrograms to find distinct audio events from which to ensure synchronization of a secondary audio track. For example, commentary that mocks a character may be played immediately after a particular noise in the audio track of a video occurs such as a door slam. Keeping the secondary audio track in synch with the audio track of a video is performed by periodically searching for distinct audio events in the audio track of a video and adjusting the timing of the secondary audio track. May utilize a sound card on a computer to both analyze a DVD sound track and play and adjust timing of the secondary audio track to maintain synchronization.
