I think it's attainable. Of course, it depends on how much time I have
and how much help I get. I estimate that removing the remain float
operation would probably take about 20-40 hours of work for the plain
CBR (not including the VBR, VAD and all). 

There are also a couple things I don't like in the current port. One of
them is that I'd like to reduce the amount of 32-bit operations (convert
some things to 16-bit arithmetic).
