Viewers forgive shaky video faster than they forgive bad audio. A Reel with clean, balanced sound feels professional even when the footage is simple, while a Reel with muddy, uneven audio feels amateur even when the footage is beautiful. The advanced audio tools in Edits exist to close that gap.
Mixing is not about expensive gear. It is about decisions: which sound leads, which sound supports, and which sound gets out of the way. This guide covers those decisions, from levels and ducking to layering effects, so your videos sound as good as they look.

30-second answer: Put speech first, music second, and effects last. Set speech loud and clear, drop music to about a third of the voice level, fade music in and out at the edges, and check the mix on a phone speaker before you export.

Why the mix matters
Most Reels are watched with the sound on, but many are first judged with it off, in a feed full of competing videos. When a viewer unmutes, the first second of audio decides whether they stay. Clean speech, a music bed that supports rather than fights, and one well-placed effect signal care, and care keeps viewers watching.
The good news is that mixing in Edits is forgiving. You are balancing three or four lanes, not forty. Our music and audio guide covers adding tracks; this guide covers making them work together.
Mix your audio, step by step
- Finish the visual edit first, so the audio mix follows the final cut, not an early draft.
- Place every sound on its own lane: speech, voiceover, music, and effects, each separate.
- Set speech first, at a level where every word is effortless to follow.
- Add music underneath at about a third of the speech level, and fade it in and out at the edges.
- Add one sound effect at a time, each quieter than the speech, and check the mix on a phone speaker.
Checking on a phone speaker is not optional. Most viewers hear your Reel through one, and a mix that sounds rich on headphones can sound muddy on a small speaker. If speech survives the phone speaker, it will survive everywhere.
Levels and balance
Think of levels as a pecking order. Speech sits at the top, music sits below it, and effects sit below that, popping up only for a moment when they matter. When two sounds fight at the same level, the viewer hears neither clearly, so one of them must always win.
Watch for clipping: the harsh, crackling distortion that happens when a sound is pushed too loud. If a voice crackles, lower it rather than raising everything else to match. Our voiceover guide covers recording clean speech in the first place, which makes the mix far easier.
Ducking music under speech
Ducking means lowering the music whenever someone speaks, then raising it again in the gaps. It is the single biggest upgrade you can make to a talking video. Without it, music and speech compete; with it, the viewer hears both, each in its own moment.
Do it by hand if Edits does not duck automatically: split the music track at each speech section, lower the sections under speech, and keep the sections between sentences at full level. Short fades at each split keep the changes from sounding abrupt. Our captions guide explains why clear speech matters even for viewers who watch muted; ducking is its audible twin.
Effects and EQ basics
Effects and EQ are seasoning, not the meal. A touch of EQ can remove the boom from a voice recorded too close to the phone, and a short reverb can make a voiceover feel less dry. But heavy effects draw attention to themselves, and a voice buried under reverb is harder to understand, not easier.
One rule covers both: if you notice the effect, it is too strong. Turn it down until it disappears into the mix, then leave it there. The best audio work is the work nobody notices.
Layering sound effects
Sound effects work best one at a time. A single click when a title lands, a soft whoosh on a transition, a quiet ambient bed under a travel clip: each one earns its place. Stack three effects at once and the viewer hears noise, not craft.
Place effects on the beat or on the cut, never in between. An effect that lands with the picture feels intentional; one that drifts feels like a mistake. Our transitions guide covers the visual side of the same timing.
Troubleshooting
Speech is hard to hear
Lower the music to a third of the speech level, or duck it under speech sections. Raising speech that already clips will only add distortion.
Music jumps in volume
Add short fades at every music split and at the start and end of the track. Abrupt level changes read as mistakes.
Voice sounds echoey
Record in a smaller, softer room next time, and keep reverb low in the mix. Effects cannot fix a roomy recording.
Mix sounds fine on headphones but muddy on a phone
Phone speakers hide bass and exaggerate harshness. Lower the bass-heavy music slightly and check speech clarity first.
Export sounds different from the preview
Export a short test and listen on a phone, as our export settings guide recommends. Preview playback can flatter a mix that export reveals.

Frequently asked questions
What does mixing mean in Edits?
Mixing means balancing your audio lanes: speech, music, and effects, so each is clear and none fights the others. Speech leads, music supports, effects punctuate.
How loud should music be under speech?
About a third of the speech level. Every word should stay effortless to follow, and the music should be felt more than heard.
What is ducking?
Ducking is lowering the music whenever someone speaks, then raising it again in the gaps, so speech stays clear without losing the music bed.
Why does my mix sound different on a phone?
Phone speakers hide bass and exaggerate harshness. Always check the mix on a phone speaker before you export.
Do advanced audio tools cost extra?
No. Audio tools are part of the free Edits app, and exports using them carry no watermark.
Can I mix audio on a PC or Mac?
Yes, inside an Android emulator running the same free app. Our PC guide and Mac guide explain the setup.

Audio for different video types
Talking-head videos live or die on speech. Keep music very low, duck it under every sentence, and skip effects almost entirely. The viewer’s attention belongs on the speaker’s face and words, and anything else is a distraction.
Product and travel videos have more room: a music bed can carry the mood between voiceover lines, and one or two effects can punctuate a reveal. Even here, speech still leads whenever it appears. The moment a voice starts, the music must step back.
Mixing mistakes that hurt a Reel
- Music at the same level as speech, so neither is clear.
- No fades, so tracks start and stop with an audible click.
- Effects stacked on top of each other until the mix turns to noise.
- Checking the mix only on headphones, never on a phone speaker.
- Fixing a bad recording with effects instead of re-recording it.
Every one of these is easy to fix once you hear it, and almost impossible to fix once the video is posted. Spend five minutes on the mix before you export, and your videos will sound like they were made by someone who cares.
A simple mixing checklist
- Speech is clear on a phone speaker, without headphones.
- Music sits at about a third of the speech level and ducks under every sentence.
- Every track fades in and out, with no clicks at the edges.
- At most one effect plays at a time, and each one lands on a cut or a beat.
- The exported test file sounds the same as the preview.
Run through this list before every export, and it will become second nature within a few videos. The checklist is short on purpose: a mix that passes five checks is a mix worth publishing.
Good audio is quiet craft. Nobody will compliment your ducking or your fades, and that is the point. When the sound disappears into the story, the story is all the viewer remembers.
When to stop mixing
Mixing has a point of diminishing returns, and it arrives sooner than most creators expect. Once speech is clear, music sits underneath it, and no effect jumps out, the mix is done. Every change after that point risks making it worse, not better.
The test is simple: play the video once, from the start, without touching anything. If nothing pulls your attention away from the story, export it. If one sound still bothers you, fix that one sound and test again. A mix finished on time beats a mix perfected too late, because the next video teaches you more than the last hour of tweaking ever will.
Speech first, music second, effects last. Check it on a phone, export it, and move on to the next video.
Listen to the audio of Reels you admire, and you will hear the same pattern: speech that never strains, music that never fights, effects that land exactly on the picture. Those creators are not using better tools than you. They are making the same five decisions, in the same order, on every video.
Make those decisions yours, and your videos will sound like you mean them to. That is the whole secret of advanced audio: it is not advanced at all, just careful, repeated, and checked on a phone.
