It happens all the time — you get a song stuck in your head, try to hum it to friends and no one has a clue what you’re talking about. You continue thinking about it until you finally hear a snatch of it again — from a TV show, the radio or in a store. Now, Google has a new way to identify it for you. You can now hum, sing or whistle the tune into your phone.
The technology to match tones to a database of identified songs through singing, humming and whistling — instead of from lyrics alone — has existed for more than a decade, and was a staple in the music app SoundHound as far back as 2009.
