how to convert stereo mp3 to mono wav?

I'm trying to convert an mp3 to a ringtone, and I need the intermediate file to be a mono wav file. I'm using this command with mplayer:

mplayer -ao pcm input.mp3 -ao pcm:file="output.wav"

and it converts nicely, but the wav is in stereo.

How do I make it mono?

Your help is appreciated,

I'm sure mplayer can do this, prob with a -m flag tho. have you looked at man mplayer?
if not look into Lame

ok, I have it so I convert the original mp3 to a mono mp3 then decode to wav using lame.

Thankyou for the suggestion!
