Shazam is a mobile application that makes use of the microphone on the device in order to determine the type of media being played based on a brief audio clip.
The software was originally developed by Shazam Entertainment
How To Shazam on Snapchat?
Open Snapchat on your iPhone or Android device and head to the camera screen.
Hold the shutter button while the music plays to take a photo. Snapchat's Shazam function uses your phone's microphone to detect songs and displays musical symbols and notes as it listens.
Shazam displays album art, song title, and artist's name when it recognizes a song. "Listen" opens your music player, while "Song Info" provides track details. To share music, click the "share" button (three dots, upper right).
Click "Play" to hear a clip of the song; lyrics are below. Swiping the window down closes it.
On your camera's display screen, you'll also see "Song Finder." Shazam-like Song Finder delivers the same results.
