I don't think so, no. MEncoder is a video encoder, not an audio encoder.
About the best you can do is
mencoder -oac pcm -novideo -endpos 30 filename.mp3 -o filename.avi
mplayer -vo null -vc dummy -dumpaudio -dumpfile filename.wav filename.avi
but that's clunky, by no means guaranteed to work, and you ought to be
able to do it more easily and perhaps better with a program which is
actually intended to do audio encoding, rather than one which does it as
a side thing to make video encoding work easier.
Warning: Simply because I argue an issue does not mean I agree with any
side of it.
