Shazam, Soundhound, Axwave, ACRCloud and others have seen considerable success by using a simple algorithm to match an acoustic fingerprint to a song in a library. These applications take a sample clip of a song, or a user-generated melody and check a music library/music database to see where the clip matches with the song. From there, song ...
The target zone of a song that was scanned by Shazam. [6] Shazam identifies songs using an audio fingerprint based on a time-frequency graph called a spectrogram. It uses a smartphone or computer's built-in microphone to gather a brief sample of the audio being played. Shazam stores a catalogue of audio fingerprints in a database.
Musipedia, on the other hand, can identify pieces of music that contain a given melody. Shazam finds exactly the recording that contains a given snippet, but no other recordings of the same piece. Musipedia is included in some library catalogs on music-finding, which include other papers and online resources. [3]
Shazam's algorithm picks out points where there are peaks in the spectrogram that represent higher energy content. [2] Focusing on peaks in the audio greatly reduces the impact that background noise has on audio identification. Shazam builds their fingerprint catalog out as a hash table, where the key is the frequency.
If there is a match, it returns the information to the user; otherwise it returns a "song not known" dialogue. Shazam can identify prerecorded music being broadcast from any source, such as a radio, television, cinema or music in a club, provided that the background noise level is not high enough to prevent an acoustic fingerprint being taken ...

In summer 1999 while on an internship in his MBA program, Barton conceived of the idea for Shazam as a service to enable consumers to find out what songs were playing where music could be heard, based on recording the song's audio and pattern-matching it to a database of songs.
