How do I remove background noise from a video or audio recording for free?

For a voice recording or a talking video, Adobe Podcast's Enhance Speech is the quickest free fix: sign up for a free account, upload the file and it cleans up the spoken audio (Premium raises the limit to 4 hours a day and files up to 1 GB). If you are editing the video anyway, Microsoft Clipchamp's free editor removes background noise and silences inside the project, so the sound is fixed and the video exported in one place. Audacity is free, works offline, and its Noise Reduction is good on a constant hum, hiss or fan, but it is not suited to traffic or a crowd. On an iPhone 16 or later, a video shot with Spatial Audio can be fixed in Photos with Audio Mix, whose In-Frame option reduces sounds from sources not visible in the shot. Push any of these too far and voices turn thin and watery, so compare with the original. Rule: Enhance Speech for talking, Audacity for a steady hum, Clipchamp when the clean-up is part of an edit.
