Strip audio from an mp4 video

[heylookitsmewow]

I have some mp4 video files and would like to take only the audio and convert it to an mp3 file so i can listen to the audio in an mp3 player. How can I do this?

Re: Strip audio from an mp4 video

One way to do it

> Avidemux

Package: avidemux-qt (or avidemux, gtk version)


If the mp4 has an mp3 audio: Audio = copy and Audio > Save...

If the mp4 audio needs conversion: Audio = MP3 (lame) and Audio > Save...


More > MPEG-4 Part 14 (MP4)

Re: Strip audio from an mp4 video

Thanks Rog131 that did exactly what I wanted. Now what program will break the mp3 file I created into several shorter ones? The mp3 is a 2 hour long audio but I would like to split it into several shorter sections.

a) Avidemux. Save the audio into short pieces (from the original mp4).

There is a slider at the bottom of the Avidemux window and letters "A" and "B". The "A" will set the start point and the "B" will set the stop point.




b) Use the mp3 splitters, one of them > HOW TO merge or split mp3 files


c) As the "vinnywright" suggested there is the Audacity. More options > Audio editors, some of them can edit the mp3's.

Re: Strip audio from an mp4 video

Actually I spoke too soon. Avidemux did create an mp3 file but it is choppy and distorted when i use the mp3 lame setting. When I use "copy" it creates a file that my mp3 player can't read. Is there some way I can solve either of these problems?

I got it to work with wavepad with wine. It always worked great on windows and didn't think of trying it on wine but it works just the same.

There is one more possibility no one mentioned - command line program ffmpeg from repository, with a lot of options but no splitting. See http://www.ffmpeg.org/ffmpeg-doc.html
