Well we removed the amr reference code support because of license
issues, so I don't think we should add more code in. The best way to do
this is to add working reference glue code to the SoC qcelp tree. Then
port the current decoder to fixed point. Then make sure the decoder is
bit exact compared to the reference source. This would remove any doubt
of compliance but it would be alot of work. There is lots of fixed point
code available in in the g729 patches that are aimed for speech codecs.
So are you up for all that work ? You could get svn commit access to the
 qcelp soc tree if that would help out your work and the review process.
