Add music to a video with ducking, fades, and sound effects

Vyra puts a track under your footage, dips it under your voice with keyframed volume, and pulls sound effects from Freesound when you ask.

Adding music is easy. Mixing it so your voice stays clear is the part that eats time. Vyra places the track, ducks it under speech with keyframed volume, fades it in and out, and adds sound effects from Freesound if you want them.

How it works

  1. Upload the footage and the track.
  2. Say where the music goes, how loud under speech versus b-roll, and how it should end.
  3. The agent places the track and keyframes the volume for ducking and fades.
  4. Ask for sound effects by name. The agent searches Freesound and places them.
  5. Export.

Prompts to paste

Add a calm lo-fi track under the whole video. Music at about 25 percent whenever I'm speaking, up to 70 percent during the b-roll. Fade out over the last 2 seconds.
Start the music on the first wide shot, not on my intro. Keep my voice on top everywhere.
Add a soft whoosh on each title card and a camera shutter when the photo appears at 0:22.

When to use something else

  • You need a licensed music library in the tool. Vyra doesn't have one. Bring a track you have rights to.
  • You want AI-generated music. Vyra places music, it doesn't make it.
  • You need a real multitrack mix with EQ and compression. Do that in an audio tool and bring the result back.

FAQ

Does it lower the music when I talk? Ask for it in percentages and the agent keyframes it.

Can I use a song I found online? Only if you have rights to it. Platforms mute videos with unlicensed music.

Where do the sound effects come from? Freesound, searchable from the Audio panel.
