YouTube has updated the audio editing capabilities it offers users, with several important improvements including an extended library of more than 150,000 backing tracks.
Other improvements include a new interface (pictured above), the ability to mix music into your video at different volume levels (from “soft background” to “completely replace”), and a choice of featured tracks that makes it easy to find a song that fits with your video's mood.
To try out these new features, go to Video Manager -- Edit -- Enhancements -- Audio.
The new features will be available worldwide over the next day, and YouTube promises more improvement to come in the future. Check out a video demonstration below.
