Shazam -an application developed by Shazam Entertainment Ltd. can identify music, movies, advertising, and television shows, based on a short sample played and using the microphone on the device
The musical magic is available for Android, macOS, iOS, watchOS and tvOS..It is one of the world’s most popular apps, used by hundreds of millions of people each month to instantly identify music that’s playing and see what others are discovering. With a touch of the Shazam button, the app takes a quick (10 second) recording of the song you are listening to and then miraculously returns the name of the artist, the song title and the album in question
Process Behind Shazam
How does Shazam work this magic, you may ask? When you hold your phone up to a song you'd like to ID, Shazam turns your clip into a digital signature /acoustic fingerprint of the frequencies , amplitude and time. Shazam creates a spectrogram (a visual display of the prominent frequencies in a track, from booming bass to fizzing cymbals), for each song in its database - a graph that plots three dimensions of music: frequency vs. amplitude vs. time. The algorithm then picks out just those points that represent the peaks of the graph - notes that contain "higher energy content" than all the other notes around it,
The main thing here is creating a 'fingerprint' of each performance .Then it's just a matter of pattern-matching - Shazam searches its library for the code it created from your clip; when it finds that bit, it knows it's found your song Shazam stores a catalogue of audio fingerprints in a database. The company has a library of more than 11 million songs, and it has devised a technique to break down each track into a simple numeric signature—a code that is unique to each track. Then when you send a recording to their library, Shazam quickly recognizes the digital signature, and presto, an answer is returned ,otherwise it returns a "song not known" dialogue.
How a fingerprint is made?
Shazam can identify pre recorded 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, and that the song is present in the software's database.
The lo-fi nature of sounds played over a mobile phone means that this analysis has to be resilient to extraneous noise, distortion, chat and general degradation You'd think that ignoring nearly all of the information in a song would lead to inaccurate matches, but Shazam's fingerprinting technique is remarkably immune to disturbances—it can match songs in noisy environments over bad cell connections.
When does Shazam Not Work?
Shazam can only identify recorded music which is in database. If you were to hum the same song to Shazam, it wont be able to recognize because acoustic fingerprint would be different, it is highly dependent on timing between anchor point pairs.
