I used Win 7 movie maker to extract a portion of a .MP4.
Now I want to extract the music to a windows compatible music file.
Then put on my cell phone.

Can something on Windows 7 or XP do this ?

If not, is there a free application to do this?

TIA

I like FFMPEG. It works with movies, sound and video.

It's command line. The following is an example only, but is
likely to work for your test.MP4 as well.

ffmpeg -i test.m4a -c:a libmp3lame -b:a 192k test.mp3

FFMPEG is normally available as source, however there are
build-meisters who make available very nice binaries.

(Example of a Static build, a nightly from February...)

You want 32bit, static, because the static version, the ffmpeg.exe
file (36MB) has all the DLLs baked into the executable. That means
your copy of ffmpeg.exe is portable and can be put anywhere you
need to use it. That's why I prefer static builds.

The included ffplay.exe, plays stuff for you. So you can
verify that at least *something* will play it.
