Extracting sound files (wav) from audio files

[William J Poser]

Another approach to extracting audio from video files is to use
the ffmpeg program, which is available at no cost here:
http://ffmpeg.mplayerhq.hu/index.html

I've only used it under Linux but it is supposed to compile
under MS Windows as well. The command line arguments are somewhat
cryptic. The command line you need is like this:

ffmpeg -i foo.avi -f wav foo.wav

The argument of the -i flag is the input file. The argument
of the -f flag is desired output file type. The last argument
is the name of the output file.
