[MPlayer-users] converting dumped audio stream to wav

[Amadeus W. M.]

I dumped an audio-only stream from an web radio station using mplayer.
I can play the dumped file ok with mplayer, but I'd like to convert it to
wav so I can cut and edit the file using e.g. audacity.

I skimmed through the docs, and I tried something like

mencoder -oac pcm -o /dev/null stream.dump

but it says 
AAC file format detected.
Video stream is mandatory!

Exiting...

Is it possible to force mencoder to ignore the video stream?

If this is not possible with mencoder, is there any other tool that will
do what I want? (convert aac to wav or mp3).




Some info that mplayer reports on that file:
