Abstract:
1. A method for performing audio copy detection, comprising: a) providing a query audio data unit having a succession of query frames; b) providing a plurality of test audio data units each including a succession of test frames; c) for each test frame, determining one of the query frames as corresponding to said test frame; d) for each of the test audio data units, determining a similarity between the succession of query frames and the query frames corresponding to the succession of test frames of the test audio data unit by (1) aligning the query frames in the succession of query frames with the query frames corresponding to the succession of test frames; (2) comparing aligned pairs of query frames; (3) determining a count of the number of times that an aligned pair of query frames is the same; e) selecting, at least in part on the basis of the similarity for each of the test audio data units, a particular one of the test audio data units as a match for the query audio data unit.
