Thanks very much for your solution. Actually, using the method of
piping sox's output to mplayer worked fine for me, aside from one
warning printed by sox. Of course, since MPlayer reads the audio from
stdin, no keystrokes are recognized, but that's not a problem when I
just want to listen to the stream from beginning to end.

The temporary file solution I could perhaps implement as a shell script.

Thanks again for your help.
