Avidemux Forum

I have a smartphone video in MP4 format encoded with AVC H.264 and AAC audio.
This video is almost perfect. What need is to eliminate/erase only some small tiny noises of approx half a second each.

How can I achieve this without re-encoding (at least without re-encoding of the video part)?

This common problem is sadly not as easy to solve as it should be. You don't need to re-encode the video however.
The easiest way would be to cut audio+video when the noise occurs, but you stated you want to only silence the unwanted sound and keep the video. So you will need to use an audio editor such as Audacity to process the audio. Care must be taken not to change audio duration or you will lose sync. You then remux the original video with the corrected audio.

Ok, thank you so far

Assume I have extracted, edited and created a new *.aac, *.wav or *.mp3 audio file.

How can I tell Avidemux (with currently loaded original video+audio file) to drop old audio track use the new external file instead?

I miss an "import audio file" menu

Audio menu/Select track
Change "Track 0 from video" to "Add audio track" and select the file.

Thank you
