Convert mp4 to mp3

Hello everybody,

Could you please suggest me a quick way to convert just the audio of movies from AC3 to MP3 ? I would like to get a new Avi with the same video, but different audio (mp3). OS: windows 7.

(I do not need to convert video, just audio)

thank you !

You can do it with ffmpeg. Try a command line like this:

ffmpeg -i <input_filename> -f <container> -vcodec copy -acodec libmp3lame -ar 44100 -ab 128k -ac 2 <output_filename>

Replace the <> stuff with whatever filenames and containers you are using. Do note that this will downmix surround to 2 channel audio.
