How to remove wind noise from a video on a Mac
Shot something great outside, only to hear wind battering the mic the whole way through? That low, roaring rumble is the most common thing that ruins outdoor clips. Here's how to cut wind noise from a video on a Mac in one tap, 100% offline: the picture is untouched, and there's no account, no upload.
The fastest way: just ask
Crisp has a plain-English box ("Or just tell Crisp what to do…"). Drop your video in and type it:
- reduce the wind noise — cut the wind buffeting
- cut the wind — clear the low rumble
- it's too windy — tame a gusty outdoor take
- wind buffeting on the mic — knock down mic wind
Crisp reads the request, switches to the Audio lane's Wind mode, and you just press the button. (It's careful about wording, too — asking to "rewind" a clip won't trigger it.)
Step by step: the Audio lane
-
Open Crisp and drop in your video
Get the free Crisp app for Mac and drag your clip onto the window. Nothing is uploaded: the whole job runs on your Mac.
-
select the clip and use Audio in the Tools panel, then Wind
In Crisp, select the clip on your timeline and use Audio in the Tools panel. Or just type “remove the wind noise” in the prompt bar — Crisp maps plain English to the same tool.
-
Press it
Crisp runs a firm high-pass to clear the low-frequency rumble that dominates wind, then a light denoiser for the residual gustiness — on-device. The picture is stream-copied untouched — only the audio is processed.
-
Save
The cleaned clip lands beside your original — with the video never re-rendered.
Cuts the rumble hard — keeps the voice
Wind on a mic lives almost entirely in the low frequencies, below where speech sits. Wind mode leads with a firm high-pass around 150 Hz — under the bulk of a voice — so the roar drops out while people stay clear and present. In a quick test, a 50 Hz wind-band tone fell about 21 dB while a 1 kHz voice tone barely moved (0.02 dB). Want the levels even afterward? Run Normalize next.
Wind vs Denoise: which mode?
Both live in the Audio lane, but they solve different problems:
- Wind — the loud, low rumble of wind buffeting a mic outdoors. Firm high-pass. That's this guide.
- Denoise — steady broadband hiss, hum, or AC drone in a room. Gentler, broadband. See remove background noise.
- Visual noise / grain in the picture — that's not audio at all. Use Enhance / Low-light.
Crisp vs iMovie vs online wind removers
| Crisp | iMovie | Online tools | |
|---|---|---|---|
| Dedicated wind-noise mode | Yes (high-pass tuned for wind) | Generic noise slider | Varies |
| Plain-English request | Yes | No | No |
| Video not re-encoded | Yes (audio only) | Re-renders | Varies |
| 100% offline, nothing uploaded | Yes | Yes | Uploads your clip |
| Price | Free tier + one-time $129 | Free | Free + upsell |
iMovie's noise slider re-renders the whole project and isn't tuned for wind specifically; online tools upload your footage. Crisp targets the wind rumble, touches only the audio, and keeps it local.
Why offline matters for wind cleanup
- Your footage stays yours. The "remove wind noise online" tools upload your clip first. Crisp cleans it entirely on your Mac.
- Video untouched. Only the audio is processed — no quality loss on the picture, and it's fast.
- No queue, no size cap. It works on the whole file locally.
- Stack it. Wind, then Normalize the levels — all on-device.
Cut the wind — offline
Free to try on your Mac. One tap to clear wind buffeting and keep voices clear: no account, no upload, nothing leaves your device.

Wind noise questions
How do I remove wind noise from a video on a Mac for free?
Use Crisp: drop your clip in, select the clip and use Audio in the Tools panel, then choose Wind (or type "reduce the wind noise"), and press it. It cuts the wind on your Mac: no account, no upload.
How does it cut wind noise?
Wind on a mic is dominated by low-frequency rumble, so Wind mode leads with a firm high-pass (around 150 Hz) that sits under most speech, then a light denoiser for the residual gustiness: the rumble drops hard while voices stay.
Is this different from Denoise?
Yes — Denoise is for steady broadband hiss/hum/AC drone; Wind is tuned for the loud low rumble of wind on a mic. Pick Wind for breezy outdoor footage.
Does it change the video?
No — only the audio is processed; the picture is stream-copied, so there's no quality loss and it's fast.

Wind is a low-frequency problem
Wind noise lives almost entirely at the bottom of the spectrum: the rumble and buffeting from air hitting the mic capsule directly. That's why a high-pass filter rolling off below roughly 80–120Hz removes a surprising amount of it while leaving speech intact, since almost no useful information in a human voice sits down there.
What can't be fixed is a fully overloaded capsule. When wind physically clips the mic, the recording has no clean signal underneath to recover. That's why a foam windscreen outdoors saves footage that no amount of processing will.
Physical protection beats every filter
A foam cover handles light breeze; a furry windjammer handles real wind, and the difference between them outdoors is not subtle. Even cupping a hand upwind of a phone mic measurably helps. None of this is a processing tip, but it's the difference between footage you can rescue and footage you can't.
Check whether there's anything left to save
Before spending time on a clip, listen to a section where nobody is speaking. If you can hear the room and the wind sitting on top of it, there's clean signal underneath and filtering will help. If the wind gusts produce a hard, crackly distortion that cuts out entirely between buffets, the capsule was overloaded and the underlying audio wasn't recorded at all.
In that case the honest options are re-recording the audio, replacing it with narration, or cutting to a different angle, not a stronger filter.
