1. Shazam A Musical Innovation By Philip Heilman

2. About the Application Shazam is a smartphone application that attempts to recognize and identify a particular music track from a 10 second clip. It “tags” or bookmarks particular tracks from a database that has over 2 million songs, and no genre preferences. There are several versions of the application, as well as competing applications that offer similar features.

3. The Technology: How it works An algorithm was created with these elements: 1. Track the correct song in a timely manner 2. Deal with ambient background noise 3. Decrease the chances of a network dropout The algorithm measures frequency and time throughout a song, and maps out the varied tones, which create audio “fingerprints” for a database.
