Why phone videos sound noisy

Audo's video noise reduction cleans up video audio in MP4, MOV, MKV, WebM, AVI files (and WAV, MP3, M4A, AAC, FLAC, OGG, Opus, WebM, AIFF audio) up to 10 GB without an account, and the first minute of each is free, 3 times a day, with no sign-up. A one-minute clip is usually ready in about 10 seconds, and an 18-minute file in about a minute. Wind, traffic, crowds, fans, and hum come down, and the speaker still sounds like themselves. For a voice that echoes or sounds muffled, Audio enhancer is the better pick.

Wind noise is gusts of air hitting the microphone: a low roar that comes and goes. A phone's microphones are small openings with nothing in front of them, so outdoor videos pick it up, along with traffic and air conditioning. The example above was filmed in a windy field.

Next time, put a foam or furry windscreen on the mic, stand with your back to the wind, or film out of it. For the videos you already have, there's no need to shoot them again.

Questions

How do I remove background noise from video online for free?

Add your video at the top of this page. Audo's video noise reduction is free for the first minute of each video, 3 times a day, with no sign-up. Longer videos are $0.05 a minute ($3.00 an hour), with no subscription needed — see pricing.

How do I remove background noise from a video on iPhone?

Use Safari or any browser on your phone: open this page, add the video, and download the clean copy. There's no app to install, and it works the same way on Android.

How do I remove wind noise from a video?

Add the video here and leave the slider at Remove most to remove wind noise from video along with traffic, fans, and hum while keeping the speaker's own voice. If the voice also echoes, use Audio enhancer instead.

Will it keep my voice?

Yes. Nothing about the voice is rebuilt: only what's behind it is turned down, so it still sounds like the person who spoke. Music counts as background here, so it gets quieter too.

Does the picture change?

No. The picture is copied as it is, so it loses no quality, and only the sound changes. An MP4 comes back as an MP4, and a MOV as a MOV.

Can I get only the sound?

Yes. Pick MP3, WAV, M4A, or FLAC under Save as in More options, and the cleaned sound comes on its own.

Can ChatGPT remove background noise from a video?

Yes, with Audo added to it. Attach the video in ChatGPT and ask it to remove the background noise, and you get the same video back, with clean sound. Claude works the same way. Add Audo to your assistant once, and it's there in every chat.

Can I clean a TikTok or Instagram video?

Yes, from the saved video. Audo takes files, not links, so save the video to your phone or computer first, then add it here and post the clean copy.
