Abstract
Systems and methods audio matching using interest point overlap are disclosed herein. The systems include determining at least one matching reference segment based on a probe segment. Interest points for both the at least one matching reference segment and the probe segment can be generated. Probe segment interest points and matching reference segment interest points can be time aligned and frequency aligned. A count can be generated based on a number of overlapping interest points between each set of reference interest points and the set of probe segment interest points. The disclosed systems and methods allow false positive reference to be identified and eliminated based on the count. The benefits in eliminating false positive matches improve the accuracy of an audio matching system.
