What is Microphone Wind Muff for?


When recording video/audio outside on a breezy day, you'll probably hear the wind 'cutting' your audio. Even a gently breeze can completely destroy an otherwise perfect audio recording, especially when you use a shotgun/condenser microphone.

Ask any videographer or sound profession and they'll tell you it's extremely difficult (or maybe "impossible") to remove wind noise in post-edit. The most useful and easiest solution to avoid all this pain? Use a wind muff!

What is Wind Muff?

The synthetic fur covers on microphones in video production are often referred to as a “dead cat” or “wind muff”. These funny looking covers can block wind from hitting the microphone, therefore reducing the wind noise from being recorded.

Three Types of Wind Muffs

Foam – Effective to block gentle wind ONLY  

This is the most common type of windscreens and is often used in the indoor/studio environment because it blocks the least amount of wind compared to the other wind muffs.

Many microphones are supplied with a foam windscreen made of polyurethane – a foam material that is effective at blocking the wind at less than 1 m/s (about 2 mph). Typically the denser a foam windscreen is, the better it is at reducing wind noise.

Dead Cat – Budget Producers’ Favorite Wind Muff

The fluffy “dead cats” use a lightweight synthetic fur material to block wind. No actual cats are injured in the making of these handy accessories – but take one look and you’ll understand why they earned their delightfully morbid industry nickname. This is the best choice for anyone with a tight budget. The furry material blocks wind, but allows audio to pass through without losing the high-frequency response of a microphone.

You can also combine the dead cat with the foam windscreen for an even better effect to block higher-speed wind: Ex. Wind speed 6 m/s (about 13 mph).

 

Blimp Windshield – The Heavy-Duty Wind Blocker

The most effective windscreen on the market is the blimp, shaped like a “pill”. Different from foam or dead cat wind muffs, the blimp is a hollow cage that creates an open chamber of space of still air around the mic.

Depending on your situation for audio/video recording, you may or may not need a blimp. If you are seeking one, make sure to check the material and weight, as the newer versions are often much lighter than the old ones.


Pro Tip

Measure your microphone so the wind muff fits well. Having a tightly-sealed windscreen is important when selecting a wind muff because wind can “cut” its way into your microphone from every direction.
