There are few simple ways to extract audio from various types of video files (MPEG, AVI, DivX, etc). Use MediaInfo to find out the audio-stream information of the video file.

Using ffmpeg

ffmpeg -i video_file -f mp3 audio_file.mp3

In order to specify a different bit rate for your output file, use the -ab switch (in b/s).

ffmpeg -ab 192k -i video_file -f mp3 audio_file.mp3

Using MPlayer

mplayer -dumpaudio -dumpfile audio_file.mp3 video.avi

That is, if the audio stream is in MP3 format. If it isn't, change extension appropriately.
