For some reason sounds were only updated/started about every 100ms,
which could lead to delays of up to around 100ms after a sound gets
started (with idSoundEmitterLocal::StartSound()) until OpenAL is finally
told to play the sound.
Also, the actual delay drifted over time between 1ms and 100ms, as the
sound ticks weren't a fixed multiple of the (16ms) gameticks - and the
sound updates didn't even happen at the regular 92-94ms intervals they
should because they run in the async thread which only updates every
16ms...
Because of this, the machine gun and other rapid firing weapons sounded
like they shot in bursts or left out shots occasionally, even though
they don't.
Anyway, now sound is updated every 16ms in the async thread so delays
are <= 16ms and hopefully less noticeable.
You can still get the old behavior with com_asyncSound 2 if you want.
OpenAL devices can disconnect, and with some luck they're back after
a few seconds. This especially seems to happen with Intels Windows GPU
driver and display-audio when switching the resolution or enabling
fullscreen, see #209
Now a disconnect is detected and we try to reset the device for 20
seconds, hoping it comes back. This needs at least openal-soft 1.17.0
to build and 1.20.0 or newer to actually work.
Also added missing stub functions in openal_stub.cpp (used by dedicated
server so it doesn't have to link libopenal)
idSoundSystemLocal::Init() didn't consider the case that opening the
default device (alcOpenDevice(NULL)) could fail, but this can happen if no
audio devices exist (or all are disabled or they're sleeping bluetooth
headphones or whatever).
Starting a map failed then with
ERROR: idSoundCache: error generating OpenAL hardware buffer
Now this and "s_noSound 1" are handled the same and one can play.
If the main sound in a shader was a .wav
(soundShader->entries[0]->hardwareBuffer == true), only that sound was
played (and looped with AL_LOOPING), even if a leadin was configured.
If the main sound was an .ogg it worked.
Not it should always work.
If an OpenAL source runs out of samples it transisions into state
AL_STOPPED. That happens if we're entering the menu (which switches
to another soundworld) and when saving the game (because the game
blocks for some milliseconds). Work around this by adding a new
field 'stopped' to the channel state and use that to determine if
a sound was stopped. And not AL_STOPPED like before.
so even with many loud sounds the overall volume isn't reduced by
OpenAL - apparently OpenAL scales down all sounds temporarily if the
mixed result would be too loud or sth like that.
Just sending all sounds to OpenAL with a lower volume prevents that from
happening (just set your system speaker volume a bit higher if needed).
This problem was especially noticable when shooting at metal walls with
the shotgun (each pellet produces an impact sound so it gets kinda loud)
* r_mode defaults to 5 (1024x768), I think that's more sane than 640x480
* r_fullscreen defaults to 0 (=> windowed mode) because fullscreen in
the wrong resolution sucks.. let people do their initial configuration
in windowed mode
* r_swapInterval defaults to 1 (=> VSync active by default) because that
makes the game feel more smooth and most PCs should be able to 60fps
in this 11years old game anyway
* s_useEAXReverb defaults to 1 (=> use EAX/EFX effects by default),
because OpenAL-soft supports them on all platforms/hardware and if
for some reason the used OpenAL implementation doesn't support it,
it's deactivated automatically anyway.
All these things can be configured in the Options Menu.
* the OpenAL function definitions mustn't include __declspec(dllimport)
=> fixed by pretending to compile OpenAL statically
* glimp.cpp shouldn't be used in dedicated-only mode (as it was already
the case on Linux and OSX)
=> No special handling for ID_DEDICATED needed in glimp.cpp, as it's not
used anyway
* add APIENTRY to every gl function in stub_gl.cpp for compatibility
with windows headers and MSVC
* remove GL/gl.h #include from win_local.h as it's not needed
* in qgl.h, when building dedicated server for windows, redefine WINGDIAPI
to nothing for SDL_opengl.h #include to get rid off __declspec(dllimport)
by using #pragma push_macro and pop_macro, because our stub is no dll.
Fixes https://github.com/dhewm/dhewm3/issues/39
Apart from some minor stuff, this changes the signature of some methods
of Parser and Token classes and of the (unused) Random2 class.
That no problem though, because the calling code uses normal ints
anyway.
Set AL_LOWPASS_GAIN like EAX did under the hood.
Set the same filter via AL_DIRECT_FILTER on sources.
This should bring the overall sfx closer to EAX:
<kaan_> it sounds awesome
All infos provided by KittyCat from #openal.
The gain values are expressed as millibels in the .efx files
and need to be converted to normalized floating points.
Get the EAX4 EAXREVERBFLAGS_DECAYHFLIMIT from the "flags" token
and set AL_EAXREVERB_DECAY_HFLIMIT accordingly.
All infos provided by KittyCat from #openal, many thanks!
First attempt at porting the EAX reverb code to EFX.
This only works when the ALC_EXT_EFX extension is supported by
the OpenAL vendor (which is not the case for the OSX supplied
framework, use OpenAL soft instead).
The current stable version of OpenAL Soft (v1.13 as of this
writing) can barely handle this additional workload, current
master is highly recommended when using this feature.
We already link to OPENAL_LIBRARY further down.
Log some debug OpenAL info, mainly so OSX users can check they are not
using Apple's OpenAL. OpenAL Soft is recommended as it fixes many
issues.
I specify it as follows:
cmake -DOPENAL_LIBRARY=/usr/local/lib/libopenal.dylib -DOPENAL_INCLUDE_DIR=/usr/local/include -GXcode ../neo/
(because FindOpenAL.cmake prefers the /System frameworks)
Don't include the lazy precompiled.h everywhere, only what's
required for the compilation unit.
platform.h needs to be included instead to provide all essential
defines and types.
All includes use the relative path to the neo or the game
specific root.
Move all idlib related includes from idlib/Lib.h to precompiled.h.
precompiled.h still exists for the MFC stuff in tools/.
Add some missing header guards.
Use the CVar s_numberOfSpeakers for that, its already stored
in there.
Add the same (!= 2 && !=6) check as in the audio backends since
the mixer is limited to these 2 values.
variable set but not used
Removes some CollisionModel code under _DEBUG which was probably a
leftover, since it was completely useless (its done later anyways).
