Thanks, is it this patch?

Is see it is at least partially committed already. I'm not sure about
the part still not in SVN, do I really need it?

What I'm having troubles now with is shift value. I tried to encode
some wav file ripped from CD with lame and decode it with different
decoders (using mplayer, -ac mad, -ac ffmp3, -ac mp3). They all are
quite similar to each other (according to tiny_psnr stats), but have a
major difference from the original file, probably because of shift.
And I have difficulties with figuring this shift out. I'll try to make
an automatic shift detection patch for tiny_psnr.c to solve this
