Detach audio from avi, edit audio, re-attach. How?

Hi guys,

What software can I use to remove audio from a video (either avi or mp4), edit it (various situations call for various edits, such as: editing, noise removal, normalizing, etc) and then re-attach the audio to the video (without affecting the video itself).

Any info or links (or "google keywords") are most welcome.

thanks

 

Use Avidemux.
Open the file, then select "audio" at the top, and you'll find a way to save it.

 

Nice and fast reply...thanks davexnet!!!

 

You're welcome.

 

Audacity is a very good program to do the audio editing. Install ffmpeg for Audacity, and then you can open the MP4/AVI...to edit the audio directly without first demuxing/separating it from the video. Then you can use Avimux Gui/Yamb/MKVMerge and remux the video with the new,edited audio.
