What is Microphone Wind Muff for?  Foam & Dead Cat Windscreens Explained

What is a 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.

When recording video or audio outside on a breezy day, you'll probably hear the wind “cutting” your audio. Even a gentle breeze can completely destroy an otherwise perfect audio recording, especially when using ashotgun or condenser microphone.

Ask any videographer or sound professional, and they'll tell you that it's extremely difficult (or maybe even impossible) to remove wind noise in post. The most useful and easiest solution to avoid all this pain? Use awindscreen!

Also called wind muffs, windscreens come in many shapes and sizes to fit different kinds of mics. There are tiny muffs that are specially made for youriPhone and GoPro microphones, as well as a plethora of big ones for professional sound recording. Before we get to our recommended microphone cover for your device, let’s first see the different kinds of wind muff and what they specifically do.

What are the Three Types of Wind Muffs?

  1. Foam Microphone Windscreens– For effectively blocking gentle wind ONLY

This is the most common type of windscreen, and it is often used in studios and indoor recording environments because it blocks the least amount of wind compared to the other wind muffs.

Many microphones are supplied with afoam windscreen made of polyurethane—a 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.

  1. Dead Cat Mic Covers– For keeping your audio clean even on a budget

The fluffy “dead cats” use a lightweight synthetic fur material to block wind. (No actual cats were 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 wind blowing at a high speed, like 6 m/s (about 13 mph).

  1. Professional Blimp Windshield– For heavy-duty wind protection

The most effective windscreen on the market is theblimp, a microphone cover that is shaped like a giant pill. It is a hollow cage that creates an open chamber of space of still air around the mic. Unlike other muffs that only cover the mic head, blimps enclose the whole microphone, including the body, to completely protect it from vibration. This is important in extreme weather conditions where the wind can shake the base of the mic and distort the sound it records. With a blimp housing the microphone and absorbing shock, noise can be substantially reduced from the final audio output.

Depending on your recording situation, 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.

One More Tip...

Measure your microphone so that the wind muff fits well. Having a tightly-sealed windscreen is important when selecting a wind muff because the wind can cut its way into your device from every direction. This is also why an airtight rubber base is an important feature to check when weighing your options.
