oggdec plays at about twice the volume of mp3dec #191

I played a list of mp3 and ogg files, and found the ogg files played much 
louder than the mp3 files. I do not have this problem playing the same files on 
Linux using XMMS or Audacious.

/rc/bin/play was used like this:

while() {
    play `{fortune $list}
}

it goes to eleven... no seriously :)

use audacity and generate some reference wav signal, encode in mp3 and ogg,
analyze in audacity... then render the mp3 and ogg files to pcm with 9front
(you can use the -o flag in play for that), then look at it in audacity again.

so we have the original pcm, and the mp3's and oggs and the rendered pcm.
