Technology: How Shazam Works To Identify (Nearly) Every Song You Throw At It
Many of us are prone to using the Shazam music-identification service whenever we encounter unfamiliar songs. After all, it’s just so easy to whip out our phones, open an app, and know everything about a mystery song in seconds. But how does Shazam gives us all this information so quickly?
Here are the basic steps: 1. Beforehand, Shazam fingerprints a comprehensive catalog of music, and stores the fingerprints in a database. 2. A user “tags” a song they hear, which fingerprints a 10 second sample of audio. 3. The Shazam app uploads the fingerprint to Shazam’s service, which runs a search for a matching fingerprint in their database. 4. If a match is found, the song info is returned to the user, otherwise an error is returned.
