Wind noise in outdoor recordings really sucks.
That constant thumping of the wind against the microphone is at least distracting, at worse it makes listening really hard to do.
Fortunately, there is a way to protect a microphone from wind noise. It's called a dead cat.
You can find many examples on eBay and Amazon but it's also easy to make one yourself, both cheaply and quickly. You can find videos on YouTube that show you how and there are a number of blog articles that not only explain what these dead cats do and how they do it, there are some that actually show you how to make your own DIY dead cat.
If you don't have the time to make your own dead cat, take a look on Amazon. Here's an example for
the very popular Rode VideoMic Pro plus microphone.
