# How to remove background noise from a video > Three ways, in order of how much they cost you. Why the fix is nearly always in the recording, and the one kind of noise nothing removes. Canonical: https://easyreels.io/blog/remove-background-noise-from-video [Blog](https://easyreels.io/blog) · How-to 23 September 20265 min read Use the noise reduction already built into your editor first: CapCut, Premiere and DaVinci all have one, and for hum, hiss and traffic it is usually enough. A dedicated tool handles worse cases and starts to make voices sound processed. Nothing reliably removes another person talking, music, or reverb from a hard room, which is why the real fix is almost always in how the audio was recorded. Noise removal is one of those problems where the tools have got very good and the advice has not caught up. Most short-video noise is now fixable in one click; the cases that are not are worth recognising quickly, because no amount of processing rescues them. ## What kind of noise do you have? This decides everything, and the categories behave completely differently. | Noise | Removable? | Why | |---|---|---| | Constant hum, hiss, fan, air-con | Easily | Steady, so it can be modelled | | Traffic, distant rumble | Usually | Mostly low frequency | | Keyboard, clicks, taps | Often | Short and distinct | | Wind | Partly | Overlaps the voice | | Another person talking | No | It is also speech | | Music in the room | No | Same reason | | Reverb, a hard empty room | Barely | Not noise: it is your voice, late | The bottom three are the ones people spend an evening on. **Reverb especially**: it is your own voice reflecting off bare walls, so removing it means removing part of what you want. Tools that claim to do it leave the voice sounding underwater. ## Start with the editor you already have Nearly every editor now has this built in, and for the top rows of the table it is enough: - **CapCut**: "Reduce noise" on the audio track. - **Premiere Pro**: the DeNoise effect, or Enhance Speech. - **DaVinci Resolve**: Voice Isolation in the Fairlight page. - **Audacity**, free: sample a second of pure noise, then Noise Reduction. Still the most controllable option. The Audacity workflow is worth knowing even if you edit elsewhere, because it is the honest version of what all the others do automatically: it needs a sample of the noise *alone*, which is why leaving a couple of seconds of silence at the start of a recording is the cheapest thing you can do for yourself. Whatever tool you use, apply the least amount that works. Over-processed audio has a distinctive swirling, hollow quality that is more noticeable than the noise it replaced, and unlike noise, it sounds like a mistake rather than like a room. ## Then a dedicated tool, if you must If the built-in one is not enough, the specialist tools are genuinely better and there is a cost: they are all doing more aggressive reconstruction, and voices start sounding processed. Use them for footage you cannot reshoot. For anything you can record again, re-recording takes five minutes and sounds better than an hour of processing. ## The fix is in the recording Almost every noise problem is a recording problem that was solved too late. In rough order of effect: 1. **Get the microphone closer.** The single biggest factor by a wide margin. Distance is what makes the room louder relative to you, and halving it does more than any plugin. 2. **Record in a soft room.** Curtains, sofa, bed, clothes. A wardrobe genuinely is better than a kitchen. 3. **Turn things off.** Fan, air-con, fridge, the laptop doing something. 4. **Record audio separately from filming.** The camera microphone is the weakest link in most reels: [voiceover on reels](https://easyreels.io/blog/voiceover-for-reels). 5. **Leave two seconds of silence** at the start. That is the noise sample every tool wants. 6. **Listen back on headphones before you finish**, not after posting. Point one is the one people skip because it feels too simple to matter. It matters more than the other five combined. ## Wind, specifically The most common outdoor problem and the least fixable in software, because it is broadband: it overlaps your voice rather than sitting under it. - **A foam cover** on the microphone, which costs almost nothing. - **Put your body between the wind and the mic.** - **Record the voice separately indoors** and use the outdoor footage silent. This is what most good outdoor short video actually does. ## When to give up and re-record Be quick about this decision. If, after the built-in reduction at a moderate setting, the voice sounds processed or the noise is still obvious, re-record. It is nearly always faster. The exception is footage that cannot be repeated (an event, an interview, a moment). There, process as far as you need and accept the artefacts, because a slightly odd-sounding real clip beats not having it. ## Where audio sits in whether a video works Bad sound makes people leave faster than bad footage does, which puts it squarely in the first second: [what the first three seconds have to do](https://easyreels.io/blog/reel-hooks-first-three-seconds). It is also one of the quieter items in [six reasons a reel looks amateur](https://easyreels.io/blog/why-reels-look-amateur), because viewers register it without identifying it. And the consistency point applies here as everywhere: the same recording setup, the same processing, every video. Re-deciding it per video is how a feed ends up with one clip that sounds like a studio and the next like a corridor. That is the same argument as the rest of the production system. Once the setup is fixed, what is left is assembly. [Easy Reels](https://easyreels.io/) takes a track, a folder of clips and a template and returns finished 1440 × 2560 files, ten or fifty at a time, cut on the beat because the cuts came from the audio. [Batch-creating reels](https://easyreels.io/blog/batch-create-reels) is that workflow. ## Common questions ### What is the best way to remove background noise from a video? The noise reduction built into your editor, at the lowest setting that works. For hum, hiss and traffic it is usually enough, and it avoids the processed sound that heavier tools introduce. ### Can I remove background noise for free? Yes. Audacity is free and still the most controllable option, and CapCut's built-in reduction costs nothing either. ### Why does my voice sound strange after noise removal? Too much of it. Noise reduction removes parts of the signal, and past a point that includes your voice. Reduce the amount until the artefacts disappear, even if some noise stays. ### Can I remove someone talking in the background? Not reliably. Speech and speech occupy the same space, so tools cannot separate them cleanly. Re-record if you can. ### How do I stop wind noise in outdoor videos? A foam cover on the microphone, your body as a windbreak, or record the voice separately indoors and use the outdoor footage without its own sound. **About this article.** Written by the team that builds Easy Reels, which edits your clips and songs into finished vertical reels from one prompt.
