How to Add Sound Effects to a Voiceover
Updated October 2026
Sound effects add texture to a voiceover, but they must not hide the words. Choose effects you have the right to use, time them to the speech, and balance them below the voice.
The short version
- Use effects you have the right to use, from your own recordings or licensed libraries.
- Time the effects to a word or a pause, not in the middle of speech.
- Keep effects below the voice, and duck them under speech.
- Use only a few effects; too many distract the listener.
Rights first
Use effects from your own recordings or from a library you have a licence for. Check the licence before you publish.
Timing
Place the effect at a word or in a pause. An effect that lands on top of a key word makes it hard to hear.
Balance
Keep effects below the voice, and duck them under speech where they overlap. The ducking explanation covers the method.
Restraint
A few well-placed effects are better than many. Remove any effect that the listener notices more than the voice.
Effects under the voice
