Sound System Rework: Phase 2 (cont'ed)

2009-12-25T11:59:04+00:00

. Fixed super fast refresh rate issue

. Recovered  shortcut key for ThrottleSkipping

. Removed redundant "soundstream->Update()" in DSPLLE
  (Thanks to LordMark)

Sound System Rework: Phase 2

2009-12-23T15:34:14+00:00

. Performance boost
  (Completely non-blocking between Sound thread and CPU thread, in the meantime keeping them thread safe)

. Both 32KHz & 48KHz sound can be handled properly now
  (But up-sampling is still not implemented, and I don't think any game requires it.)

. Strategy adjustment
  When your PC is *NOT* capable to run the game at 100%:
  >> DSound    Could yield more fluent sound than OpenAL sometimes, but you will lose the sync between video & audio (since audio is played before video to guarantee fluency)
  >> OpenAL    Ensures video & audio are always sync'ed, but sound could be intermittent(to let slow video catch up)

. Changed default frame limit to: Auto
  (Somehow this can dramatically decrease the chance of wiimote desync in game NSMB)

Sound System Rework: Phase 1

2009-12-22T07:26:30+00:00

. Fixed Sample Rate for DSP
  (Now if your CPU is capable to run game at 100%, you will get pure sound without buzz or static noise)

. Fixed Sample Rate for AI
  (Now if your CPU is capable to run game at 100%, you will get sync'ed video and audio)

. Fixed Backend list for DSPLLE

. Improved Aduio DMA a bit
  (There might be a completely redesign in following phases)

WARNING: The whole rework will take time to complete.
This commit is compilable, but could be unstable.
So you can try it and test it but don't take it as a release rev!

Now OpenAL works, at least.

But Dolphin's sound stream system really needs a rethink.
Because this is the root cause of constant blocking.

Add the mixer change from issue 1479 (use sleep(1) instead of cpu yield)

Fix aram handling in wii mode - was doing strange things with aram AND mem2 space - only mem2 exists on wii. Let me know if this breaks anything...
Fix Wii BS2 HLE - don't zero out bytes 6 and 7
Thanks to skidau for finding the ssbb error cause :)
Fixes issue 303
Fixes issue 1479

get rid of the '¯' chars in source code...non ascii chars are not really good to have floating around for no reason. http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml?showone=Non-ASCII_Characters#Non-ASCII_Characters

Now ALL copyright dates are fixed to the legally correct year: The year in which the project began. Now we don't have to change it every year :)

No more SleepCurrentThreads in Command Processor. Some Fifo cleanup.

Attempt to calculate actual refresh rate (i.e. a CPU-GPU synced Mhz), no real success. Anybody have any ideas?

Is there no indication from the game when the screen refresh should occur? No, not what I could find, we currently calculate the refresh rate and m_VBeamPos from the CPU ticks progress. That works perfectly if the CPU and GPU is perfectly synced as in the single core and no-idle skipping mode. So I guess it's possible that the game doesn't indicate when the screen should be refreshed, but rather that the hardware calculate that from the CPU ticks progress. That leaves us with a problem in the dual core and idle skipping modes to calculate a CPU-GPU synced CPU ticks progress.

a NEED DEBUG version of openal sound system, nakee, try to FIX it! :)
