Forgotten the name of a song but you can hum the melody?

Well you’re in luck as Google have just announced “hum to search” which allows users to search for a song without knowing its title or lyrics by simply singing, humming or whistling the melody.

The feature is currently available on both iOS and Android, with the latter providing the feature in over 20 different languages.

To use the feature, users of the Google app on a mobile device can tap the mic icon and say “What’s this song?” or click the “Search a song” button.

Then they start humming or singing the tune for 10-15 seconds.

Google will then deliver a sample of matches, beginning with the highest per cent match.

Check out how it works here:

“An easy way to explain it is that a song’s melody is like its fingerprint: They each have their own unique identity,” a post on The Google Blog says.

“We’ve built machine learning models that can match your hum, whistle or singing to the right ‘fingerprint’.”

“When you hum a melody into Search, our machine learning models transform the audio into a number-based sequence representing the song’s melody, models are trained to identify songs based on a variety of sources, including humans singing, whistling or humming, as well as studio recordings.” the post continues.

“The algorithms also take away all the other details, like accompanying instruments and the voice’s timbre and tone. What we’re left with is the song’s number-based sequence, or the fingerprint.”
