[PSX] Plug-in PEOPS DSound 1.10b SVN3/4/5

Plug-in PEOPS DSound 1.10b SVN5

• One more speed boost - skip zero volume channel data (another +10 fps).

Plug-in PEOPS DSound 1.10b SVN4

• Fix phase inversion (reverb channel input) (Suikoden 2 - Tinto Mines)

Plug-in PEOPS DSound 1.10b SVN3

• Speed boost! - optimize sound card writing method (DSound)
• Handle emu lags better (DSound)
• Getting around +10 fps in Threads of Fate overall. So it's nice for slower systems.
• Save / load states should handle better now (less old music playing).

Plug-in PEOPS DSound 1.10b

• Main volume $3fff -> $7fff max (Die Hard Trilogy - Die Hard 1 stage music)
• fix dll version #s

Plug-in PEOPS DSound 1.10a

Fix ADSR

Plug-in PEOPS DSound 1.10

Features:

• Rewrote Async, Timing, ADSR, Noise, IRQ, VAG, XA, CDDA, Decoded buffer engines
• Rewrote Output drivers (DSound, XAudio 2), Save state support
• Partial rewrites of Reverb, Dma, (Gaussian) Interpolation, FMod, Envelope cores
• Added pseudo-5.1, 7.1 support, xa/cdda/output filters, latency/volume control

Release 21

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)

changes:

• fix ADSR fractions (Resident Evil 3)
• fix reverb volume $3fff -> $7fff (Resident Evil 2)
• new output spu blocker (all games, buffer quality + improved latency)
• fix XA / CDDA distortion (all games)
• fix XA / CDDA interpolation (all games)
• fix XA / CDDA timing
• fix 1.00 Gaussian strengths
• fix SPU timing (Actua Soccer 2 + FIFA dropouts)
• fix A/V sync (Novastorm)
• fix mono + frequency response to work correctly
• $1000 jumps for dead channels creates halt (Metal Gear Solid)
• SPUsetframelimit to bypass spu blocker (shark only)

ADSR Sustain Level

• = Fixes FF7 cursor
• = Fixes DQ4 music
  
• = Fixes lots of other sounds, music
  

Mix fmod into output

• = Fixes Xenogears save icon (high pitch)
  

VAG fixes - $7 loops

• = Fixes missing Xenogears sounds
• = Jungle Book gets music, gameplay now
  

VAG fixes - silence flag

• = Allow IRQ generation until release

Voice on/off detection - immediately within same apu cycle

• = Fixes loop hangs, buzzes

Emu crash protection

• = Handle save states better

Async timing improvement

• = Looping the FF7 cursor menu works better (more like Eternal now)
• = Jungle Book gameplay pauses much less
  

Latency = 20ms

• = Less pops, crackles for async changes

CDDA ISO support

• = Emus like PCSX-Reloaded
• = Maybe Mooby's CDR plugin
