It was only used for Windows XP and lower.
This also bumps the _WIN32_WINNT define in the stdafx precompiled headers to set the minimum version as Windows Vista.
The two instances of this class were sharing a frac variable causing
audio glitches when both were running (which is now all the time).
Fixes issue 7463 (Since DTK merge, audio has staic in it).
The code actually handles this case correctly; the algorithm is linear
interpolation between the two closest samples, and the way it is written
should work correctly with any ratio.
The primary motivation here is to make sure we submit samples from the
CPU thread. This makes sure the timing of related interrupts accurate,
and generally keeps the different kinds of audio synchronized. This will also
allow improvements to audio dumping functionality.
The new code is also more concise because it gets rid of some duplicated
audio mixing code.
This reverts commit 4990b8910b.
The commit is causing substantial performance issues for the DSound
backend which I somehow didn't catch during testing.
Pretty straightforward; IDirectSoundNotify lets you register for
notifications after a certain amount of sound has played, so use that
instead of depending on Update() notifications from the CPU thread.
Also, while I'm here, reduce the buffer size by a factor of 4; this seems
to reduce the latency, although the difference is sort of subtle.
This is good for a couple of reasons: one, it gets rid of duplicated code,
and two, DSP emulation shouldn't need to interact with audio in the first
place.
- remove unused variables
- reduce the scope where it makes sense
- correct limits (did you know that strcat()'s last parameter does not
include the \0 that is always added?)
- set some free()'d pointers to NULL
The default async api allow us to set some latency options. The old one (simple API) was the lazy way to go for usual audio where latency doesn't matter.
This also streams audio, so it should be a bit faster then the old one.
* Currently there is no DEBUGFAST configuration. Defining DEBUGFAST as a preprocessor definition in Base.props (or a global header) enables it for now, pending a better method. This was done to make managing the build harder to screw up. However it may not even be an issue anymore with the new .props usage.
* D3DX11SaveTextureToFile usage is dropped and not replaced.
* If you have $(DXSDK_DIR) in your global property sheets (Microsoft.Cpp.$(PlatformName).user), you need to remove it. The build will error out with a message if it's configured incorrectly.
* If you are on Windows 8 or above, you no longer need the June 2010 DirectX SDK installed to build dolphin. If you are in this situation, it is still required if you want your built binaries to be able to use XAudio2 and XInput on previous Windows versions.
* GLew updated to 1.10.0
* compiler switches added: /volatile:iso, /d2Zi+
* LTCG available via msbuild property: DolphinRelease
* SDL updated to 2.0.0
* All Externals (excl. OpenAL and SDL) are built from source.
* Now uses STL version of std::{mutex,condition_variable,thread}
* Now uses Build as root directory for *all* intermediate files
* Binary directory is populated as post-build msbuild action
* .gitignore is simplified
* UnitTests project is no longer compiled
This fix the 1h32 audio bug which outputs static sound after 1h32.
The mixer is used for 32->48kHz resampling and as output buffer for the async audio backends.
So this buffer was indiced by a writing and a reading pointer and the count of samples in it.
As this is redundant and the sample count isn't accurate calculateable because of the interpolation,
both indices gets out of sync. So after some time (~92min), this buffer overflows and return only garbage.
thx @ moosehunter + delroth for debugging on this issue. You did the most work :-)
Also, some tab/space mismatches removed from VideoOGL, and some places I missed in VideoDX[number] projects.
Now, the Core is literally the only project with tab/space mismatches (on a large scale).
This commit mainly elaborates on some messages a little more. Also fixes some typos that slipped through the last commit.
A large change in text can be seen in EXI_DeviceMemoryCard.cpp. I added more info as to why a write to a memory card may fail. (This actually was a reason I was unable to write to a memcard recently).
Elaborations can be seen in WGL.cpp
I did change some comments in some files that I was correcting logging messages in, however this is only if I spot a typo or if an abbreviation is lower-cased. Even in that case, the amount of changes done to comments is very minimal.
* OpenAL:
Changed SoundTouch to use float samples, allowing SSE to be used. Made the DPL2 decoder disabled by default. Re-added the audio hack used by the Accurate VBeam emulation option.
Added a latency setting to the audio settings. Removed the Sample Rate setting. It is now hardcoded to 48000hz (accurate audio timing).
Skipped timestretching if the emulator is running below 10% speed to prevent buffer overflows.
Removed the synchronisation between the CPU thread and the audio thread. Added code to detect and resume from buffer underruns. Disabled the ability to change the DPL2 option after the game has started. Fixed a memory leak that occurred in the DPL2 decoder. Fixed the OSX build.
Build fix
Added a Dolby Pro Logic II (DPL2) decoder in the OpenAL backend. DPL2 audio is decoded to 5.1. Code adapted from ffdshow. Added an option in the DSP settings to disable the DPL2 decoder in case Dolphin incorrectly detects a 5.1 audio system. Updated the OpenAL files to OpenAL Soft 1.15.1 in the Windows build.
Removed the system timing hack which was activated when the Accurate VBeam option was enabled.
Fixed the include directories in Audio Common for the Windows 32bit build.
Fixed the include directories in Audio Common for the Windows build.
Messed up the static include line
Fix include paths and compiling in Linux. Externals soundtouch is 1.7.1, while Ubuntu 12.10 is 1.6.x. Externals soundtouch is compiled with integer samples, while ubuntu is compiled with float samples. Float samples is probably the more common route. If you're going to use soundtouch, you should probably use SAMPLETYPE instead of explicitly choosing short. This probably breaks the windows build since its includes aren't setup.
OSX: typedef signed char BOOL
OSX build fix
Build fix
Added audio time stretching by using the SoundTouch library.
Implemented correct audio timing.
OpenAL for Windows initial commit
Added code to detect and resume from buffer underruns.
Disabled the ability to change the DPL2 option after the game has started.
Fixed a memory leak that occurred in the DPL2 decoder.
Fixed the OSX build.
Added an option in the DSP settings to disable the DPL2 decoder in case Dolphin incorrectly detects a 5.1 audio system.
Updated the OpenAL files to OpenAL Soft 1.15.1 in the Windows build.
Fixes issue 3023.
They are currently broken and cause sound issues which are not present in other
backends:
* OpenAL plays music 2x too fast in Zelda UCode games with HLE
* Pulse backend uses a lot of CPU power and slows down emulation significantly
Both backends are currently being re-implemented in separate branches of
Dolphin, so this should be a temporary removal.
the intent is to replace the haphazard scheduling and finger-crossing associated with saving/loading with the correct and minimal necessary wait for each thread to reach a known safe location before commencing the savestate operation, and for any already-paused components to not need to be resumed to do so.
XGRA Extreme-G Racing Association/Conduit 2... Enabled 48kHz output for LLE (before it was just 32kHz). I hope it works, if there are serious problems, it will be reverted.

move much of the build settings to .props files
-please use them as much as possible in the future, instead of changing individual projects
NOTE: to avoid left over blobs, clean your builds *before* applying these changes.
TODO: add DebugFast target for projects that are lacking it. Lack of DebugFast targets cause the linker to use LTCG when we don't want it.
please test for regressions which could be caused by being too happy with compiler flags :)

case they are included in several .cpp files.
Also a few other minor LTO fixes.

and just operate on lists of object files instead.
This helps with LTO since LLVM/clang LTO is completely broken
by static libraries. It also helps identify symbol clashes
between components like the former plugins.
Many linkers also expect static libraries to form a strict DAG
which turns out be a difficult rule to uphold in practice,
especially since some of our platforms aren't picky about this.
LTO builds currently appears to crash at runtime because of
the static wx libs.

Fix some debugger issues. Still need to get sound window working, but the invalid id panic alert is fixed.
Also, a ";" as a comment in an ini file is now only allowed at the beginning of a line. The debugger has settings strings with semicolons in them. That completely broke the debugger.

and use wxGetKeyState on platforms other than Windows.
I am not sure if wxGetKeyState is unreliable on Windows or if
the use of GetAsyncKeyState() is simply historical, but for now
I've left the Windows call in there just in case.
This does mean that Host_GetKeyState() is currently only valid
for the small set of keycodes that overlap between wx and Win32,
one of which is VK_TAB/WXK_TAB.
Anyway, please test wxGetKeyState on Windows and remove the
ifdef if it works, so we can extend it to the remaining hotkeys.

This WILL temporarily break the Linux and MacOSX builds but should be easy to fix.
Things left to do:
* The UI on the new Audio tab for the LLE/HLE choice is ugly
* At times the code still look "plugin-y" and needs cleanup
* The two plugins should be merged further. DSPHLE should use the emulated memory etc of DSPLLE as much as possible, so that simply saving the DSPLLE state is enough. This would also bring the possibility of savestate compatibility between the two plugins.
