How to extract the audio track from a movie file

[paddyo]

I found a sound clip on the web.
The uploader posted it with a useless photo montage.
So what could have been a .mp3 of about 6 Mb is a .mp4 of almost 40 Mb.

How can I get only the sound.

Format : mpeg-4
audio codec : ACC

Thanks

Use Avidemux a free video converter, only takes a few seconds to get the audio. Here's how.

I tried and failed.

I read at the bottom of the link that it is written that file in AAC does not work. My file is AAC. That could be the problem.

VLC ( http://anonym.to/?http://www.videolan.org/ ) should usually work:

-Select convert/save from the media menu
-Add the file to convert
-Click on convert/save
-Choose the desired audio format under settings and adjust the profile if needed
-Click save

If that fails you might want to try Super:

To demux Mp4 into elementary streams, use tsMuxer.

The VLC did not do it.
I used to have the SuoerC. It is a great converter.
That will be my next try.
