How to Reduce Wind Noise in Recordings

To reduce wind noise in a recording, cut the low-frequency rumble first, then run what's left through the free Noise Reducer, using Voice mode for speech or Music mode for anything with instruments. Gust thumps that overloaded the mic won't fully come out, so trim or fade the worst ones and blend the result rather than going for 100%. Everything runs in your browser, and your audio never leaves your device.

Order matters here. The low cut does most of the work on wind, and noise reduction handles what the filter can't reach.

What wind noise is (and why it's harder than hiss or hum)

Wind noise doesn't travel to the mic the way a voice does. It forms right at the capsule: moving air breaks into turbulence as it passes over and around the mic, and those small, fast pressure changes push the diaphragm as if they were sound. Most of that energy sits in the low frequencies, which is why wind comes across as a rumble or a flutter rather than a hiss. When a gust hits the capsule directly, you get a thump or a pop, much like a plosive "p" on a vocal mic.

That makes wind a different problem from the other common kinds of background noise:

• Hiss is steady broadband noise, spread across the spectrum and most audible in the highs. How to Remove Hiss from Audio covers it.
• Hum is tonal, a drone on 50 or 60 Hz and its harmonics. See How to Remove Hum and Buzz from Audio.
• Wind is low, uneven and changes from second to second. A light breeze can be fairly steady; gusts come and go without warning.

That last point is the hard part. Most noise reduction assumes the noise is roughly constant. Wind often isn't. For fans, traffic and room noise, the wider guide is How to Remove Background Noise from Audio.

Spotting wind on a spectrogram

Drop the file into the Spectrogram. Wind shows up as bright, blotchy patches along the bottom of the display that swell and fade with the gusts, unlike hum's thin steady line or hiss's even haze across the top. If the blotches reach well up into the mids, the gust was strong, and probably clipped. How to Read a Spectrogram explains the axes and settings.

What you'll need

• A file you already have, in MP3, WAV, FLAC, M4A, AAC, OGG, Opus or WebM audio. Some versions of Safari can't decode OGG or Opus, so if one won't load, try another browser.
• For the Noise Reducer, a file up to 100 MB and 12 minutes long. Trim a longer one first with the Audio Cutter.
• Headphones. Laptop speakers barely reproduce the low end, so you can't judge wind rumble, or a low cut, on them.

Step 1: cut the low rumble

A low cut (also called a high-pass filter) removes everything below a set frequency. Speech carries very little useful energy down there, so you can cut quite firmly before the voice suffers. Music needs a gentler touch, because kick drums and bass live in the same range.

You have three ways to do it on Vocal Cut:

The Audio Enhancer in Voice mode. This is the quickest route for speech. Voice mode applies a fixed 80 Hz high-pass filter, a clarity EQ, compression, and loudness normalization to −16 LUFS with true peaks held under −1 dBTP. A Strength slider controls how hard the EQ and compression work. Music mode uses a much lower 30 Hz rumble filter and normalizes to −14 LUFS. The Enhancer also has a "reduce steady background noise" option, which is on by default in Voice mode. It's a good one-click pass for a breezy voice clip, though you can't move the cutoff. Because the Enhancer already reduces steady noise and sets the loudness, you can skip the final Volume Normalizer pass in Step 3 if you go this route.

The Audio Master Rumble filter. If you want to choose the cutoff, Audio Master has a Rumble filter slider that runs from 20 to 100 Hz. For speech, somewhere around 80–100 Hz is a typical starting point. For music, stay lower and check that the kick and bass still sound full.

The Equalizer. It's a 6-band graphic EQ with fixed bands: an 80 Hz low shelf, peaking bands at 240 Hz, 750 Hz, 2.2 kHz and 6 kHz, and a 12 kHz high shelf, each adjustable from −12 to +12 dB. There's no true high-pass, but pulling the 80 Hz low shelf down by 8 to 12 dB works as a rough low cut. If the gusts leave a boomy residue above that, trim the 240 Hz band by a dB or two. Go carefully, though, because that band carries the body of a voice and too much cut makes it sound thin. Flatten resets every band if you overdo it.

Whichever you use, listen to a gusty section and a calm one. The rumble should drop clearly while the voice stays natural.

Step 2: clean what's left with the Noise Reducer

1. Open the Noise Reducer and add the low-cut file. Drag it onto the drop zone or click to choose it.
2. Pick a mode. Voice (the default) uses GTCRN, a small AI speech model, and suits podcasts, voice memos, interviews and video narration. Music uses spectral processing, not AI, and suits songs, mixes and field recordings with instruments in them.
3. Click Reduce noise. The button reads Reduce noise (Voice mode) or Reduce noise (Music mode). Processing runs in a background worker with a progress percentage and an estimate of time left. In Voice mode the first run downloads the AI model (about 0.5 MB) and the engine that runs it, and both are cached for next time. It still takes a while on a long file.
4. Set the mix. The slider runs from Original to Denoised and starts at 75%, shown as "Noise reduction: 75%". Try somewhere between 70% and 90%. Full strength tends to leave the watery, underwater artifacts that make cleaned audio sound processed.
5. Export as WAV (the default), MP3, or Opus where your browser supports it.

How each mode handles wind is worth knowing before you choose.

Music mode builds its noise profile from the quieter, steady part of the signal, roughly the level each frequency stays under 20% of the time. A constant breeze rumble fits that profile, so it gets turned down. A gust doesn't: it's loud and brief, so the profile mostly ignores it, and it passes through. Music mode can tame a steady wind bed but won't do much about gusts.

Voice mode works differently. The speech model keeps what sounds like a voice and suppresses most of everything else, so it can often reduce wind under speech that a spectral gate leaves behind. It has two limits. It can't bring back words that were buried under a loud gust or flattened by a clipped thump, because that information isn't in the file. And it's the wrong tool for music: the tool warns that it removes everything that isn't a voice, so instruments, pads and reverb tails go too, and the output is mono and focused on the speech band. How AI Noise Reduction Works explains why.

Step 3: deal with the gusts that are left

After the low cut and noise reduction, a few hard thumps may still stand out. Those are usually gusts that clipped the mic. Clipping happens when the signal goes past the loudest level the mic or recorder can capture, so the waveform is flattened and the damage is baked into the file.

• Cut them. If a thump lands at the very start or end of a clip, trim it off with the Audio Cutter. For one in the middle, cut the parts before and after it into two files and rejoin them with the Audio Joiner. Only do this where a short gap won't be noticed.
• Fade around them. For a thump at the start or end of a clip, a short fade with Audio Fade softens it.
• Level the result. Removing rumble and gusts takes out real energy, so the file may sound quieter. Run it through the Volume Normalizer at the end, after cleanup rather than before.

How to remove background noise from a video with wind in it

The tools above work on audio files, so for a video clip, start by pulling the soundtrack out of the video file you already have with Video to Audio. Run the extracted audio through Steps 1–3, then put the cleaned track back in your video editor in place of the original sound. Keep the clip at its original length, and avoid trimming its start or end, so it lines up with the picture again. Cutting gusts out of the middle will knock it out of sync, so for video, lower a gust's volume in your video editor instead of cutting it.

When the result still isn't right

The voice sounds thin. The low cut is too high, or you pulled the 240 Hz band down too far. Lower the cutoff or give some of the 240 Hz cut back.

It sounds watery or underwater. Too much noise reduction. Pull the Original/Denoised slider back toward Original.

The music got eaten. You probably used Voice mode on music. Switch to Music mode and lean on the low cut instead.

A gust is still loud. It likely clipped, and no filter can rebuild a flattened waveform. Cut it, fade it, or re-record the line if you can.

How to reduce wind noise at the mic

Every fix above costs something. Keeping wind off the capsule costs almost nothing, and it's the only way to deal with gusts completely.

• Use a windscreen. A foam cover helps with light air and breath. Outdoors, a furry windjammer (often called a "deadcat") does far more, because the fur slows the moving air before it reaches the mic.
• Use your body as a shield. Turn your back to the wind and keep the mic in your own lee. A wall, a car or a tree works too.
• Hide the lav. A lavalier mic tucked under clothing, with a small furry cover, stays out of the wind. Make sure the fabric doesn't rub on it.
• Shelter a phone mic. Cup your hand loosely around the mic opening without covering it, or keep the phone in a case that shields it. If your phone's recording app has a wind noise filter, switch it on.
• Leave headroom. Gusts are sudden peaks, so record with room to spare. How to Set Recording Levels on an Audio Recorder and How to Avoid Clipping on an Audio Recorder cover how much.
• Mind the angle. Placement changes how much wind reaches the capsule as well as how close the voice is. Mic Placement for Clean Voice Recordings covers the basics.

Frequently asked questions

Can you completely remove wind noise from a recording?

Not always. A steady breeze rumble can be reduced a long way with a low cut and noise reduction, and an AI speech model can often reduce wind under a voice. But a strong gust that hit the mic hard often clipped the recording, flattening the waveform, and no tool can rebuild what was lost. For those moments, cut the gust out or turn it down, or re-record the line.

Does a high-pass filter remove wind noise?

It removes a large part of it. Wind noise concentrates in the low frequencies, so a high-pass filter (low cut) set around 80–100 Hz for speech takes out much of the rumble while leaving the voice intact. It won't remove gust energy that reaches higher up into the midrange, so follow it with noise reduction, and use a gentler, lower cutoff on music so the bass survives.

Why does my phone recording pick up wind noise even in a light breeze?

Phone microphones are tiny, exposed openings with little or no wind protection, so even gentle moving air creates turbulence right at the mic and reads as low rumble. Holding the phone so your body blocks the wind, cupping a hand loosely around the mic opening, or turning on the recording app's wind filter if it has one all help more than fixing it afterwards.

Is it better to prevent wind noise or fix it afterwards?

Prevent it whenever you can. A foam windscreen or a furry windjammer stops wind before it reaches the capsule, and nothing is lost. Fixing it afterwards always trades some audio quality: a low cut thins the low end, noise reduction can leave watery artifacts, and clipped gusts can't be repaired at all. Use cleanup tools for what got through, not as the plan.

Can I remove wind noise from a video?

Yes, by working on its audio. Extract the soundtrack from the video file with a video-to-audio tool, apply a low cut and noise reduction to it, then replace the original sound with the cleaned track in your video editor. Keep the clip's length unchanged so it stays in sync with the picture, and lower the volume on gusts in your editor rather than cutting them out.
