RTFS :) that is the fixed point amr code, i faintly remember that some
fixed point reference implementation just used hardcoded float emulation
or so, dunno if that was amr, if its fake fixed its useless as it wont
be faster than float with emulation on no FPU systems
if OTOH its proper fixed point code it will be faster and we shouldnt
drop support for it
benchmarks are of course usefull too ...
