i do have some doubt that it cant just be done with half the operations
that said, thats not holding the code up from svn, because we dont know if
or how that could be done.
whats holding it up is the lack of any proper review, ill try to do that

one thing that would help me is some text/spec that describes the algorithm
(that is sbr as a whole not the filterbank)


> [01:50:50] <peloverde> However i think requiring new SIMD code is really out of the scope of a new decoder

i never asked for simd optims


> [01:51:07] <peloverde> and writing really fast scalar C is a waste of time

didnt ask for that either

i too am in favor of having -mt in 0.6 :)

my gpg key expires 2010-05-26, and will be bumped by me to 2011
around that time, i never understood what expiration is good for if one can
just change it at will but thats how gpg works, you guys have forgotten to
get the key update last year i guess
