I think you can use lame to do it.

You can take a page out of this script.

cat convert2mp3.pl 
#!/usr/bin/perl -w
use strict;

foreach my $file (@ARGV) {
next if ($file !~ /\.wma$/i);
my $base = $file; $base =~ s/\.wma$//i;
system "mplayer \"$file\" -ao pcm -aofile \"$base.wav\"";
system "lame -h \"$base.wav\" \"$base.mp3\"";
unlink("$base.wav");
print "$base.wma converted to mp3.\n";
}

I personaly prefer using a pipe. :)

Here is my "mp32mp3.sh":
#!/bin/bash

echo "Converting mp3 to mp3..."
if [ $# -lt 2 ]; then
        echo "Usage: $0 <dest-dir> <abr> <mp3_1> <mp3_2> ..."
        exit 1
fi

DEST="$1"
ABR="$2"

shift
shift

for a in `seq 1 $#`; do
        echo "* Converting \"$1\"... "
        exit 1
fi

DEST="$1"
ABR="$2"

shift
shift

for a in `seq 1 $#`; do
        echo "* Converting \"$1\"... "
        mpg321 -q -w - "$1" | lame --abr $ABR - "$DEST"/"$1"
        if [ $? = 0 ]; then
                echo \[done\]
        else
                echo failed
        fi
        shift
done

% END

Fek. There are doubled lines....
I should have kept my mouth shout up. I corrected that.
