How to add a voiceover to a video — and make it sound great

1. Pick the right room

Echo is the most common problem with home voiceovers, and no microphone can fully fix it. Hard, bare surfaces — tiles, glass, empty walls — bounce your voice around the room and make it sound distant and hollow.

• Choose a small room with soft furnishings: a bedroom with curtains, a rug and a bed is ideal.
• Try the wardrobe trick. Recording facing an open wardrobe full of clothes gives surprisingly dead, clean sound.
• Avoid kitchens and bathrooms, and don't record in the middle of a large empty room.
• Kill background noise: close windows, switch off fans and air conditioning, and put your phone on silent.

2. Choose (and place) your microphone

Any of these will work — placement matters more than price:

• Phone or laptop mic. Fine for a start if you get close to it and your room is quiet and soft.
• Headset or earphones with a mic. Keeps the mic at a steady distance from your mouth — often better than a laptop mic.
• Clip-on (lavalier) mic. Cheap, discreet and consistent. Clip it to your collar, about a hand's width below your chin.
• USB microphone. The biggest step up for narration. Plug it into your computer and select it when your browser asks for microphone access.

For a desk mic, position it about 10–15 cm (4–6 in) from your mouth and slightly off to one side, so the bursts of air from "p" and "b" sounds (plosives) don't hit it directly. A pop filter — or a thin sock stretched over the mic — helps too.

3. Write a script for the ear

Even if you like to improvise, a short script or bullet list keeps you focused and saves editing time. Writing to be heard is different from writing to be read:

• Use short sentences — one idea each.
• Use everyday words and contractions ("it's", "you'll") so it sounds natural.
• Say it the way you'd explain it to a friend, then write that down.
• Leave room for the pictures. Don't describe what viewers can already see; add what they can't.
• Plan your length. Most people speak at roughly 130–160 words per minute when narrating. A 30-second video fits about 65–80 words.

Read the script aloud before recording and rewrite anything you stumble over.

4. Delivery tips

• Warm up: hum, yawn and read a paragraph aloud first. Your first take is rarely your best.
• Smile while you talk — it genuinely changes how your voice sounds.
• Slow down slightly. Nerves make everyone speed up.
• Stand or sit up straight so you can breathe freely.
• Keep water nearby and avoid dairy right before recording; it can make your mouth sound "clicky".
• If you make a mistake, pause and repeat the whole sentence. Clean restarts are easy to edit; fixes in the middle of a word aren't.

5. Step by step: record a voiceover in VDOAPP

Our free online editor records straight from your microphone while your video plays, so you can time your words to the pictures.

1. Edit the video first. Arrange and trim your clips so the timing of the pictures is final.
2. Put on headphones. In the Audio tab, Mute video while recording is on by default to stop echo. With headphones, you can untick it and hear the video as you speak.
3. Place the playhead where the narration should start.
4. Press 🎙 Record. The first time, your browser asks for microphone permission. After a 3-2-1 countdown the video plays and a REC timer appears.
5. Stop by pressing the button again, or let it stop at the end of the video. Your recording appears on the timeline with a waveform.
6. Adjust. Select the voiceover to move its start time, change its volume (up to 200% for quiet mics), play it back or delete it. Record more takes for different sections if that's easier.
7. Add music. Lower other sound under voiceovers (on by default) automatically drops music and clip sound while you're speaking and brings it back up in the gaps.

Microphone recording needs a secure connection, which vdoapp.com always uses. If your browser doesn't ask for permission, check that the microphone isn't blocked in your browser's site settings.

6. Mixing voice and music

• Voice first. Music should sit clearly underneath the narration. If you have to strain to follow the words, the music is too loud.
• Pick music without vocals for narrated sections. Two voices at once are tiring to follow.
• Use the gaps. Let the music swell briefly between sentences and at the end.
• Listen on a phone speaker as well as headphones. Most viewers will hear it that way.
• Use music you have the rights to. Look for royalty-free libraries or tracks licensed for your use.

Quick checklist

• Quiet, soft room with fans and notifications off
• Mic a hand's width away, slightly off-axis
• Script read aloud and tightened
• Headphones on (or video muted while recording)
• Levels checked with a short test recording
• Music lowered under speech
