Abstract

The present invention describes a method for detection of audio content match. The method is fast and capable of accurately detecting match for an audio content. Further, the method is capable of improving match times for a sample of audio exposed to noise and distortion, in inverse proportion to the amount of noise in the sample. The method is also capable of matching very fast a relatively noise free audio sample, further, with incremental noise in the audio sample resulting in a gradually increasing in time for match. Moreover, the method offers a substantial improvement in the ability to reject false positive matches, resulting from the use of a technique whereby for the same set of matched feature points, a greater amount of information relating to matching of the clips is derived, significantly improving the ability to reject false positives.
