I am using Audacity 2.2.2 in Windows 7 on an HP G72-260US Notebook laptop. I am new to Audacity (I’ve only been using it for a few weeks), and I’m using Audacity on a school project. In one of my classes in school, we are making documentaries. I’ve been taking video on my iPhone 8 and have imported the videos into my computer, and they’ve been automatically saved as QuickTime Movies. I’ve been using Audacity primarily as a noise-reduction tool, since a majority of the video was shot outside in the wind. I select the clip that I want to edit and import it into Audacity as an mp3. I can reduce the wind noise to a level I am happy with, but I am reluctant to go further. I am not sure if there is a way to export the edited audio with the video. I really don’t want to go through all the extra trouble of cutting the original audio from the video, then matching up the edited audio, then piecing it all together in the proper order in a video-editing software (I am using the latest version of OpenShot). When I go to export the file, the only available formats are “MP3,” “WAV,” “OGG,” “Audio,” and “Multiple.” I have already tried using multiple, since I thought it would export both the audio and video, but that does not work because it says that I have only one unmuted track. I am reluctant to use the other formats because they are all audio formats, and I’m not sure if it will properly export with the video. My main question is this––is there any way to export the audio and have it automatically match up with the video, or I am I going to have to go through a very complicated process of cutting, editing, and pasting?
Audacity will open and extract the sound file from a supported video, but that’s it. You need a video editor to put your corrected sound track back in.
We can help with the wind sound. Effect > Equalization: Low Rolloff for Speech. This is a pitch filter that drops most sounds lower than 100Hz or so. That’s thunder and trucks going by. That will help with the gut-punching rumble sound that wind can cause. The grownups use a similar filter for live video shoots under difficult conditions. Theirs is built into the mixer.
That’s the “bent line” switch. Note it looks similar to the bent line in Effect > Equalization.
Fair warning, if the wind is loud enough, it will damage the sound channel and nothing makes it through.
This is where the microphone is on my iPod. If yours is in a similar place, see if you can tape a thin, doubled-over trip of tissue paper over the microphone, all the while not blocking the round camera lens to the right.
This is why splitting the sound shoot from the video camera happens really quick after you find out how hard it is to maintain good quality with everything in one camera.
Do you have two iPhones? Shoot the video on one and put a sock over the other one and use that for sound. You’re planning on splitting the sound anyway, right? You can double record the sound and pick the best one.

I frequently mux modified audio tracks back into videos with a tool called MKVToolNix GUI. If you can deal with using the MKV format, then I highly recommend it.
“Multiple” means export the track(s) as multiple separate audio files.
If you want audio edited in audacity to remain in-sync with the video you can’t alter its length …
