Hum

Google just announced a new feature that can help you discover the song you’ve been singing in your, head by humming, singing or whistling a tune on your mobile.

All you need is the latest version of the Google app or use the Google search widget to activate the feature.

To use the feature, tap the microphone icon and say “What’s this song?” or click the “Find a song” button and start humming for about 10-15 seconds.

Google’s learning algorithm transforms the “audio into a numerical sequence that represents the melody of the song”, helping to locate possible matches in the song.
