music file identification
music file identificationSearching a music database for missing album information (meta-data) in an MP3 or other digital audio file. Although MP3, AAC and other compressed audio formats include fields called "tags" for this meta-data (see ID3 tag), the data may be missing or incomplete. Such files can be identified by using an "audio tagger" program to analyze their waveforms and create an acoustic fingerprint that is matched against a fingerprint database. See Gracenote MusicID, MusicBrainz, music CD identification and music search.
