Hello Gabriel,
U just did a profile on one of my test files (will do profile on
castanets.wav later).
My system is a Pentium 166 Mhz MMX, over clocked at 200 Mhz, using 10 ns
SD-RAM (96 MB)
I've used the Intel Performance compiler on Windows 32 (about 15% faster
than regular MSVC). I still have some mods laying
around which will combine the window_subband and filter_subband functions,
will come back later on the actual improvements
I get with these using Lame 3.05 and send the source mods to Mark.
Albert
Enough set, here are the result
