Deadcat vs Foam: Which Wind Protection Do You Actually Need?
Share
Wind noise is the one audio problem you cannot fix in post. Once that low-frequency rumble is baked into your recording, no plugin will cleanly remove it without gutting the dialogue underneath. The only real solution is stopping the wind before it hits the capsule.
But walk into any gear discussion and you'll hear three different answers: foam, deadcat, blimp. They are not interchangeable, and using the wrong one is why so many outdoor shoots come back with unusable audio. Here's how to choose.
The three levels of wind protection
Think of wind protection as a ladder. Each rung handles more wind than the last — and adds more bulk.
1. Foam windscreen — indoor and near-still air
The foam sleeve that ships with most microphones. It stops plosives (the burst of air from "p" and "b" sounds) and very light air movement. That's it.
- Good for: indoor interviews, studio work, podcasting, voiceover, static talking-head shots
- Stops working: the moment you step outside. Even a gentle breeze will get through foam
A common mistake is assuming the included foam is "wind protection." It isn't — it's a pop filter that happens to look like one.
2. Furry windcover / deadcat — outdoors, real wind
The fur — often called a deadcat, windjammer or windcover — is what actually handles wind. The long synthetic fibres break up moving air before it reaches the mic, killing the low-frequency rumble that foam lets straight through.
- Good for: any outdoor shooting, run-and-gun, moving shots, handheld gimbal work, weddings outdoors
- Stops working: in strong, sustained wind, where you need an air gap as well as fur
If you shoot outdoors at all, this is the piece of gear you're missing. It's also the cheapest upgrade with the biggest audible difference.
3. Blimp / basket + fur — high wind and professional location sound
A blimp (or basket windshield) suspends the mic inside a rigid, hollow cage, creating a pocket of still air around the capsule. Add a furry cover over the basket and you have the full system — the setup you see on every film set.
The basket also isolates the mic from handling noise, which matters enormously on a boom pole. The Radius Mini-ALTO works this way, with a matching Nimbus furry cover slipping over the top for serious wind.
- Good for: film and documentary, boom work, coastal or open locations, any professional location sound
- Trade-off: bulk, weight and cost — but there is no substitute when the wind picks up
Quick decision guide
| Your shoot | What you need |
|---|---|
| Indoor interview, podcast, voiceover | Foam windscreen |
| Outdoor vlog, YouTube, Reels | Furry deadcat over the mic |
| Wedding, outdoor ceremony | Furry cover on lav + on-camera mic |
| Documentary, run-and-gun outdoors | Basket windshield + furry cover |
| Film set, boom pole, open location | Full blimp system (basket + fur + suspension) |
| Coastal, rooftop, high wind | Blimp + fur, and consider a longer fur |
What about lavalier mics?
Lavs need wind protection too, and it's the most commonly skipped step. A lav clipped to a jacket outdoors will pick up wind just as badly as a shotgun — worse, because it's often more exposed.
The fix is a small furry cover made for lav capsules. If you're also fighting clothing rustle, that's a separate problem solved with concealment gear — see our Hidden Mic Solutions range and our guide to hiding a lav under clothing.
Does wind protection muffle your sound?
This is the fear that stops people using it — and it's mostly unfounded.
A good furry cover takes a small amount of high frequency off the top. In practice, that loss is inaudible compared to the wind rumble you'd otherwise be recording. A cheap, badly-made cover is a different story: dense, matted fur can genuinely dull your audio.
The rule: use a quality windcover sized for your mic, and the trade-off is negligible. Use no wind protection outdoors, and your take is gone.
Getting the size right
This is where most people go wrong. Wind protection is not one-size-fits-all — a cover made for a short mic will leave a longer shotgun's capsule exposed, and an oversized basket adds pointless bulk.
