P.E.Op.S. PSX Sound emulation plugin 1.6

**aldo** · April 5th, 2003

05. April, 2003 Version 1.6

Eric added another interpolation mode, called "cubic
interplation". That one offers a better treble than the
gaussian mode (imho), so give it a try.
Xodnizel has coded a xmms audio plugin, based on the
PCSX and P.E.Op.S. spu open sources. You can find his work
here: http://xod.starmen.net/sexypsf/
Doing this he found some apparent bugs in the spu plugin,
and he was kind enough to inform me (Pete) about them:
a small buffer overflow did happen when gaussian interpolation
was used, prolly that's the reason for the distorted sounds
some users reported.
So I've decided to increase the interpolation helper buffer, that
a) will fix the issues and b) it gives more room for even
better interpolation techniques in the future.
Because of that change I had to clean up the save state loading,
though... maybe some of your old save states will have no
sound after loading, sorry. Of course easy to repair: play a bit
until the sound reappears, or save the game to a memory
card file, restart the game, and load that save instead.
I've also fixed a small bug with save states, which could cause
crashes when the state was loaded with a different interpolation
mode as it was saved before.
Also please note (Linux users only): the newest RedHat 9
will come with a new thread library (Posix style). I don't know
how it will affect the spu plugin (which is using the pthread
library), but there are already known problems with the nVidia
drivers or Wine, for example. So, if you are in doubt: feel free
to compile your own plugin... the full sources can be found, as
always, on: http://sourceforge.net/projects/peops/
The same applies to the ALSA port, some users (including me,
ehehe) had trouble to run linuzappz's ALSA port, so prolly
it would be best if you compile your own plugin version (didn't
help on my system, though )
