If you want to just extract the audio stream and not re-mux it into a
video file, then you should use mplayer:
$ mplayer -vc null -vo null -ao pcm -benchmark
Then you can probably use sox to convert audiodump.wav into IMA ADPCM.
Note that I haven't tried this and there might be a better way... you
should be able to make it work, though.
