Hello list,

I have added a 1200 bit/s version to rev 318.  

It's still a little experimental so I haven't popped up any samples yet.
It's based on a 24 bit/frame vector quantiser for the LSPs that
Jean-Marc developed.  In this case it's not predictive, i.e. it doesn't
use frame-frame differences.  I wasn't sure if prediction would give us
significant gains on 40ms frame updates.

It's supported by c2sim and the stand alone encoder/decoder c2enc/c2dec.
Still needs some tweaking to get it up to the same level as the scalar
36 bit/frame LSP quantiser.

Thanks,

David
