ok i ported some of the 3dnow code, the equinvalent c code from libac3 too 
which does work but compare says the difference is larger than +/- 1
the C code is allso 2% faster than the current C code in liba52
do u want a patch or should i commit it?
committing would require to copy srfftp.h & srfftp_3dnow.h -> liba52/
