US Patent 10459973 Unordered matching of audio fingerprints

A method includes determining, at a processor of a device, an unordered match between a set of consecutive portions of a first audio fingerprint and a set of non-consecutive portions of a second audio fingerprint. The method also includes setting, based at least in part on a station associated with the second audio fingerprint, a length criterion to indicate a first length or a second length. The method further includes, in response to determining that a length of the unordered match satisfies a length criterion, outputting an indicator that the first audio fingerprint matches the second audio fingerprint.
