Good to know
Auto ducking
Lowers the music by itself while someone is speaking.
Fade in and out
Start the music softly and let it end without a hard cut.
Mixer
Set the level of every track so the voice stays clear.
Even loudness
Export can normalize loudness to −14 LUFS, the level YouTube and Spotify use.
Questions about adding music to video
Is it free to add music to a video?
Yes. There is no watermark and no account. You add an email address once, before your first export.
Is the library music free to use?
Yes. It is composed in your browser for each project and is free to use in any video, including commercial work.
Can I use any song?
You can add any audio file you have, but you need the rights to publish it. Otherwise platforms may mute or block the video.
How do I make the music quieter than the voice?
Lower the music track in the Mixer, or use Auto ducking to lower it only while someone speaks.
