Abstract
Methods and systems that utilize fingerprints or metadata to identify digital audio files are disclosed. In particular, in certain embodiments a fingerprint of a digital audio file may be utilized to find a set of fingerprints that are related to the fingerprint of the digital audio file it is desired to identify. Using the metadata associated with each of the set of related fingerprints a song, artist or album can be identified and assigned to the digital audio file it was desired to identify. Additionally, the identified song, artist or album name may be associated with the digital audio files corresponding to each of the identified related acoustic fingerprints. In this manner, not only can digital audio files be identified but additionally, data associated with previously identified digital audio files may be iteratively refined by associating updated metadata with previously labeled digital audio files.
