Well you can look it up in the archives if you want to.

And it totally defeats the purpose of a lossless compression 
algorithm. If it's going to be lossy anyway we might as well use 
Vorbis only.

You could just use 17-bit values and then use a specialised Huffman 
coder (or likely something more advanced) to reduce entropy. That 
would be a correct solution and it would still be efficient.
