Ways to cut through the noise
If you are experienced in making videos and shooting movies, commercials or even TV series, then you know how stressful it can get when you have to do on location sound recording while working outside. But you yourself might know some tricks on how to avoid your audio from getting messed up and keep it clear even if the wind is blowing. First of all you need to make sure your microphone is not opposite of the wind direction, so it isn't hit by the wind, but is set so that wind simply blows by it. That way you can avoid most of the problems, but still you won't get your clear audio.
There are tools that can help you
Professional microphones might cost quite a lot, but if you want that perfect audio, then you will consider investing. If you really don't have the budget to buy a microphone that costs as much as a professional DSLR camera, then you will need to figure something out. There are companies out there, like Rode that makes equipment for the normal video maker, like caps for lenses, stands, lights and even microphone furs. They even have microphones that don't cost that much and still can make your sound quite amazing compared to other ones in the same price range.
If you are dealing with some other noise that cannot be blocked out by a fur or special microphone, then you will need to figure out some other ways. This is when your skills make the audio great, so don't worry, with time you will manage to find some solutions. Some creators use blocking panels, like many who shoot documentaries in the wilderness where you have more noise than you can comprehend. Others try editing and canceling out noise with modern programs and tools, but those are quite hard to work with and if you are still making videos for fun, then you shouldn't bother with those.
