HumFinder turns a hummed tune into a shortlist

Field notes

The homepage provides separate entry points for a remembered tune and music playing nearby. It recommends humming for at least eight seconds and explains that imperfect pitch and timing make a ranked list more appropriate than one asserted answer. The catalogue is described as mostly independent releases, so popular songs may not be represented. For submitted music, the site says it fingerprints the audio, deletes it from its server, and has a person review each submission.
