If I'm interpreting you correctly, the first thing which springs to mind is:

mkfifo myfifo

mplayer <stream URL> -novideo -ao pcm:fast:file=myfifo

And then use myfifo as the input file for the convert-to-proper-codec
program. (If you do intend to do this purely in realtime, then the
"fast" option can I believe be safely omitted.)
