How to Fix Bad Audio in a Video
Bad video audio can be fixed in post without re-shooting — here's how to replace, clean, or enhance the audio track depending on what's wrong
Video with bad audio — background noise, muffled sound, echo, or low volume — that needs fixing without re-shooting?
The fix for bad video audio depends on what's wrong. There are three main scenarios: (1) The audio has consistent background noise (HVAC, traffic, room hum) — AI noise removal on the audio track handles this. (2) The audio has specific technical problems (clipping, too quiet, severe echo) — dedicated repair tools address each problem. (3) The audio is so poor that it's unusable — overdubbing (re-recording the voiceover separately and syncing to the video) is the most reliable option. The general workflow: extract the audio track from the video, fix the audio as a standalone file using the appropriate tools, then re-embed the cleaned audio into the video. Most video editors handle this without re-encoding the video track.
