The system allows the rapid normalization and synchronization of a plurality of content files using an audio synchronization scheme that reduces computational overhead and provides reliable results. In one embodiment, the system accepts a plurality of content files, performs spectral peak extraction and performs correlation in the log-frequency domain using subtraction. This is used to calculate a reliable confidence score for the calculated correlation. The system uses short duration samples from the beginning and end of a content file and limits the frequencies being matched to time-delay estimation in a very processing-efficient manner. |
