something like this works
$ mkfifo pcmpipe21
$ mplayer -af volume=-16,equalizer=11:11:10:5:0:-12:0:5:12:12,format=s16le
 -ao pcm:file=pcmpipe21 input.mp3
$ lame pcmpipe21 out.mp3

But the quality is not good.Using ffmpeg as a frontend give me better results
$ mkfifo pcmpipe21
$ mplayer -af volume=-16,equalizer=11:11:10:5:0:-12:0:5:12:12,format=s16le
 -ao pcm:file=pcmpipe21 input.mp3
$ ffmpeg -i pcmpipe21 -acodec libmp3lame -ab 128 out.mp3

ffmpeg do the needed housework and pass is to lame. You probably need
to adjust the parameters like bitrate and the pre-gain. I dont did
much testing.
