Improve sound and add background audio

Even out the voice, reduce background noise and play your own audio under the video.

The Audio tool makes speech clear, and lets you add an audio track you have the rights to.

Improve the voice

  1. Open the Audio tool (on a phone, Sound).
  2. Under Voice, adjust Footage sound.
  3. Switch on Level for social. It evens out loud and quiet parts to the loudness Reels, TikTok and YouTube expect.
  4. Switch on Reduce background noise to soften hum, fans and room hiss behind the voice.

Add background audio

  1. Under Background audio, choose Add audio from library. If your audio library is empty, upload your own: a voice-over, ambience or a sound you have the rights to.
  2. Choose Use. The track shows In use.
  3. Set the Level, and Use this part with Start and End to pick a section.
  4. Set Fade in and Fade out, or switch on Loop to the video's length.
  5. Switch on Lower it while someone speaks. It follows the transcript, so speech always stays clear.
  6. Choose Stop using background audio to remove it.

Tips

  • Keep background audio quiet. The voice should always lead.
  • Only use audio you made or are allowed to use.
