Wind blowing across a phone microphone makes a rumbling noise that is hard to remove later.
Shield the microphone
Turn your body so you block the wind, or film with the wind behind you. Shooting beside a wall or a car gives shelter.
Use an external microphone with a windshield
A small clip-on microphone with a foam or fur cover reduces wind much more than a phone does alone. Make sure it is compatible with your iPhone.
Move closer to your subject
Closer microphones pick up more voice compared with wind.
Do a test clip
Record five seconds and listen with headphones.
Wind reduction is built into our app and still being tested. It is not released yet and results will depend on your phone and conditions.
