64 bit build: http://sjeng.org/ftp/lossless/mp4als_x64.exe

Does it required a win64 plateform ?

Which compiler did you use for sse/sse2 ?


btw, I'm testing your different builds. Thanks for your work.

Of course. All 64 bit programs need a 64 bit OS.

This is a bit exceptional because:

a) core arithmetic in ALS is in 64 bits
b) compiler does a real bad job of optimizing it in 32 bit mode

Assembler coding can probably give a good gain in 32 bit mode, while 64 bit compiler code should be close to optimal.

Meh. I want Dual Core, too.
