Besides humming, the new YouTube song search
In addition to humming, the new YouTube song search will also let you record the song you're hearing in the background using your phone's microphone to find it, similar to the Shazam/SoundHound apps, Android Authority writes.

Humming a song into your phone that you know nothing about
Humming a song into your phone that you know nothing about except the beat and part of the lyrics in order to find it is nothing new in technology, considering that Google Assistant and the SoundHound app have been offering this feature for a long time.

Feature tested on the YouTube platform
However, it is nice to see that the company has decided to test the function for one of the world's most popular platforms for listening to music.

The company emphasizes that only a select number of YouTube and Android users can try out this feature right now. To enable it, you need to switch from YouTube Voice Search to Song Search.

How the feature works
After that, you have to hum or record a song you hear in your surroundings for at least three seconds. The new tool will then send them to relevant content on the platform related to what you recorded.

Changes and official launch
This means that even if the feature passes testing, it may experience changes in the way it works until the official launch for everyone. However, we believe that it will be similar to existing applications that perform similar searches.
