Updated with OpenAL Soft 1.20.1

Original Links





This project is for a DirectSound DLL replacement. It implements the

DirectSound interfaces by translating the calls to OpenAL, and fools

applications into thinking there is a hardware accelerated sound device. EAX is

also implemented (up to version 4) by using OpenAL's EFX extension, allowing

for environmental reverb with sound obstruction and occlusion effects.

Ultimately, this enables DirectSound applications to enable their DirectSound3D

acceleration path, and turn on EAX. The actual processing is being done by

OpenAL with no hardware acceleration requirement, allowing it to work on

systems where audio acceleration is not otherwise available.

Or more succinctly: it enables DirectSound3D surround sound and EAX for systems

without the requisite hardware.

Source Code


To build the source, you will need CMake 2.6 or newer (you can get it from

<http://www.cmake.org/>). You can either use the CMake GUI, specifying the

directories for the source and where the build files should go, or using one of

the command-line programs, for example by first making sure to be in an empty

directory where the build files will go (such as the provided build/ sub-

directory) and running cmake with the path to the source.

Once successfully built, it should have created dsound.dll.



Once built, copy dsound.dll to the same location as the desired application's

executable. You must also provide an OpenAL DLL in the same location, named as

dsoal-aldrv.dll, or else the DLL will fail to work. Some applications may need

to be configured to use DirectSound3D acceleration and EAX, but it otherwise

goes to work the next time the application is run.

Source releases, the Git repository, and Windows binaries for OpenAL Soft are

available at its homepage <http://kcat.strangesoft.met/openal.html>.

Instructions are also provided there.

Sadly seems this updated OpenAL-Soft can cause crashing in New Vegas, for me at least crashes started in/around Camp Forlorn Hope.
Some diagnosing showed this updated version to be the cause, reverting back to the version in the DSOAL pack on New Vegas NexusMods let things work fine again.

Tried building a new version of dsoal to see if that'd fix things (the dsound.dll in this pack), but that just crashed at the main menu, too bad since maybe updated dsoal would work better with newer OAL-Soft.
(Just to be sure I tried building latest OAL-Soft too and had exact same results as the version from here, tried with both VS2019 & Clang)

      Hello everyone, I would like to clarify why my editing in the article on sound is constantly canceled?
      Here is the evidence on the pictures below about the difference in sound on the spectrograms.
      As you can probably notice, that on Windows 10 samples are more identical to the original, rather than on Windows 7.
      Used materials in this tests

      Source sound

      Windows 10 on Realtek

      Windows 10 on Creative G1

      Windows 7 on Realtek

      Windows 7 on Creative G1

      The peculiarity of this behavior in terms of sound in Windows 7 was caused by the introduction of DRM at the development stage of Windows Vista, which is also easily confirmed by reading the development literature.
      To carry out this test, recording through the line input via the built-in sound card with the help of Audacity was used and then the results were transferred to the schedule through the Spek.
      The conditions were the same (Volume 80% output and input) and the same player Foobar2000 on default settings (no asio/openal and ks with wasapi exclusive for output) was used.
      For very talented people, I note that the sound system has remained the same since Windows Vista, but has been significantly reworked: https://www.head-fi.org/threads/windows-10-has-better-sound-quality-than-windows-7-on-my-computer-not-necessarily-yours.789224/
      Especially it is important for the old and not-so games that use DirectSound.
      And for those who like to listen to music, and especially in a high quality, because windose 10 does not force you to use all sorts of workarounds crutches mentioned above.

      This is a pack containing a compiled OpenAL Soft libraries and softwares for Linux use. It was compiled by me (KayX291) in order to help newcomers with using OpenAL Soft without trying to compile it by themselves. It can be used for specific software which uses OpenAL or use it in your system as a replacement.
      The main difference between OpenAL and OpenAL Soft is the fact that the latter is not only open source, but also a support for mono, stereo, 4-channel, 5.1, 6.1, 7.1 and HRTF output. But with the configurator, you can customize and even enhance the sound output with filters, effects etc.
      It contains:
      - OpenAL Soft libraries
      - OpenAL Soft GUI Configurator
      - HRTF files
      - alsoftrc sample file
      and more.
      They are available in both 32 bit and 64 bit versions.
      Dependencies required:
      Qt5 and pressumably SDL2 (For GUI configurator to work)
      Compiled on:
      ArchLinux - 64 bit
      Manjaro 17.0.6 (via VirtualBox) - 32 bit
      Loki Software for OpenAL
      KCat for OpenAL Soft
      Me for compiling em
