How to balance video and music volumes for a short ad

Your short ad may sound fine while you edit, then the music drowns out the voice on a phone. Or the music feels so quiet that the ad loses energy. A few careful listening checks can help you find a balance that works on small speakers and headphones.

Start with the most important sound, usually the voice or original clip audio. Then set the music underneath it, listen to the mix at a normal volume, and check the exported video before posting.

Balance the audio in your video editor

1. Find the original audio from your video and the music track in your timeline. If you want to mix audio separately, the Audio Editor can place audio files on tracks and export a WAV or MP3. It does not edit video, so you would need to bring the finished audio mix back into your video editor.
2. Play a section where someone speaks, if the ad has a voice. Set the original clip or voice to a comfortable, clear level first. Keep an eye on the editor's audio meter, and reduce the level if it reaches the clipping area.
3. Lower the music until every word is easy to understand. Bring it up gradually until it adds energy without competing with the voice. As a starting point, music may need to sit roughly 12 to 20 dB below speech, but the recording and arrangement matter more than a fixed number.
4. Listen to the beginning, the busiest section, and the ending. If the music covers a line, use volume automation or keyframes to lower it during speech, then raise it in pauses or at the end.
5. Export the ad and play the exported file on a phone speaker and headphones. Check the whole ad, including the first second and final second, because a mix can feel different outside the editor.

If the voice and music are already mixed together in one video audio track, you usually cannot adjust them independently. Look for separate source tracks or return to the project that created the mix.

What the result means

You can understand every word and still hear the music

The balance is likely working. The music supports the ad without pulling attention away from the message. Check the exported version at a normal listening volume, not only with headphones turned up.

The voice is hard to understand when the music plays

The music is masking the speech. Lower its level during spoken lines, or use volume automation to make brief dips under the voice. If the voice still sounds buried, the recording may also be too quiet, muffled, or noisy.

The music sounds weak when the ad has no speech

There may be no voice to anchor the mix, so the music can take a more prominent role. Raise it until it supports the visuals without sounding harsh or distorted on a phone speaker. Keep enough headroom that the loudest moment does not clip.

The mix sounds balanced in the editor but wrong after export

Check the exported file itself. The editor preview may use a different playback level or output device, and social platforms may process audio after upload. If the exported file already sounds distorted, reduce the mix level and export it again.

Fix common volume problems

1. Lower the music first. Reduce the music track a few decibels, then replay the same spoken line. Make small changes and listen again rather than pulling the music down by a large amount at once.
2. Make dips under speech. If the music is clear in pauses but masks words, lower it only while someone is speaking. Use keyframes or volume automation in your video editor, then listen for sudden jumps when the music returns.
3. Check the voice track on its own. If it sounds faint or unclear without music, fix the voice recording before changing the mix. A low or muffled voice cannot always be made clear by turning up the whole track.
4. Check for clipping. Look at the audio meter during the loudest moment. If it reaches the red area or the sound crackles, reduce the level of the combined mix. Turning down the phone or computer volume does not repair clipping already baked into the file.
5. Compare playback devices. Listen on a phone speaker, headphones, and your usual editing speakers if possible. Phone speakers have limited bass, so a low, bass-heavy music track may sound much thinner there than it does in the editor.
6. Recheck the export settings. Export a fresh file after the changes and play it from the beginning. Confirm that the original audio and music are both present, the ending is not cut off, and the file is not peaking into distortion.

Why a single volume number is not enough

Audio meters can show peak level, which is the loudest instant in a sound. A peak reading does not tell you how loud the whole clip feels. A sharp sound can peak high but seem brief, while steady music may feel prominent even with lower peaks.

That is why listening matters more than matching two numbers. Set the voice so it is clear, then adjust music by ear across the full ad. Avoid making the music barely audible just to keep every word prominent. The mix should still feel intentional during pauses and at the end.

If you use the TooLab Audio Editor to prepare a separate mix, the audio files you open and export stay on your device.
