US Patent 7774385 Techniques for providing a surrogate heuristic identification interface

Surrogate heuristic identification is described, including a memory configured to store audio data associated with audio content, and a processor configured to select a portion of audio content, and the portion is standardized, to identify a characteristic associated with the portion, to use the characteristic to generate a data representation, the data representation being used to provide heuristic data associated with the audio content, and to process the heuristic data to generate a fingerprint associated with the audio content, and the fingerprint is configured to compare to one or more stored fingerprints to detect substantially similar audio content.
