Shazam is a commercial mobile phone based music identification service. Shazam uses a mobile phone's built-in microphone to gather a sample of music being played. An acoustic fingerprint is created based on the sample, and is compared against a central database for a match. If a match is found, information such as the artist, song title, and album are relayed back to the user. Relevant links to services such as iTunes, YouTube, and Spotify allow users to find your music in these services.
Currently, around 350 million users are tagging more than 10 million tracks a day. The service was expanded in September 2012 to enable TV users in the US to identify featured music, access cast information and get links to show information online, as well as adding social networking capabilities.
Shazam offers two types of applications; a free app simply called Shazam and a paid app called Shazam Encore. Shazam and Shazam Encore provide the same music tagging and identification functionality, with unlimited tagging of music and TV content. However, Shazam Encore removes the advertising that helps to support the free version of Shazam. Shazam Encore users can also enjoy Full Track playback with Spotify. Shazam also powers song identification for Siri in Apple's iOS.
Shazam is capable of identifying your music and generating relevant to your music in third party services such as YouTube, iTunes or Spotify.
It takes between 24-48 hours after delivery to have your tracks available for identification by Shazam.
Shazam is available worldwide (200 + countries).
