[iiwusynth-devel] Changes on CVS

[Markus Nentwig]

Some changes now on CVS:
--enable-longlong ./configure option: Uses long long for phase
calculation, slightly faster.
--enable-SSE option: Use Pentium SSE extensions for some buffer copying.
Interpolation is also coded in SSE, but currently disabled. It's still
slower than the original. Somebody, who knows some assembler, might make
a big difference here.
All over all, the improvements gained through using SSE were quite
disappointing. Peter's original code is too fast, that takes all the fun
out of optimizing...
- Filter: The filter will now smoothly interpolate between two settings
over the length of one buffer.
- Reverb: Fixed a problem with denormal numbers causing floating point
exceptions. The reverb is quite a bit faster now.

The 'loop point modulation SEGV' is still unfixed. Next week...

Cheers

Markus
