P.E.Op.S. DSound PSX SPU v1.9a r21 is released. P.E.Op.S. DSound PSX SPU is the Windows PSX spu emulation plugin, using DirectSound, which can be used with the win32 ePSXe emulator software.

__hankhoser__ knows audio quality. And found more bugs that forced major rewrites to almost everything. Main thing to know is this: quality + compatibility is hugely improved because of these findings Important changes: - async wait = spu blocker (runs at your audio card rate which is typically ~59.8 fps or possibly ~50 fps with emu region framelimiter) Uses a sleep timer to cut down on cpu usage. - async on-demand = spu blocker w/ spin loop. 100% cpu usage for rock solid fps (suggested to turn off gpu framelimter) You will be limited to ~59.8 or ~50.0 unless your emu supports SPUsetframelimit.
