Universal mod for other Unreal Engine 4 games?

[ThreeDeeJay]

Hi there, is there any chance this could be adapted to other UE4 games?
I recall some UE3 games could be forced to use OpenAL but often resulted in no audio, so I'm guessing the soundbanks need to be converted which I assume is what the AL_Sounds folder is. Some UE4 games could use x3daudio1_7_hrtf, but that's been abandoned and usually doesn't work on UE4.24+ 😔

UE4-ALAudio-Win64-Shipping.dll was compiled from UT4 source code so it is completely native to game.
Originally OpenAL (ALAudio) audio module was set to be build for Linux only. I've made changes for it to be build for Windows too.
Implemented missing low-pass filtering, reverb, fixed various bugs, ... all the stuff listed in release notes.

To work with other UE4 games it would most likely require to compile UE4-ALAudio dll for every UE version and to match with a version a particular game is based on.
The chances of it working would depend how much UE was modified and if loading of different audio modules is not disabled.

AL_Sounds folder is used for modified sounds to reduce overall noise profile/chaos in UT4 and is optional.
There is a video under 2023-10-21 release notes demonstrating it.

x3daudio1_7_hrtf uses hooking to achieve functionality. That approach would be more universal without dll matching assuming it is adjusted for every specific case when it does not work properly.

compile UE4-ALAudio dll for every UE version

I wonder if it'd be possible to set up Github actions to compile it for every version kinda like I did here to compile older DSOAL with its contemporary OpenAL Soft retroactively 🤔

Makes sense 👌

x3daudio1_7_hrtf uses hooking to achieve functionality. That approach would be more universal without dll matching assuming it is adjusted for every specific case when it does not work properly.

Other than not being compatible with newer UE4 (I think since the audio overhaul that added spatial audio renderers) or anticheat engines blocking it, X3DAudio HRTF is surprisingly compatible. Though sadly it's based on an ancient OpenAL Soft, so it requires old MHR HRTF format, and lacks features like reverb. I wonder if it could be repurposed into a wrapper to let OpenAL Soft handle all the audio mixing on its own. Though I'm not sure the dev is planning to update it any further.

On the bright side, I just tried your UT4 mod and works like charm, even with the latest OpenAL Soft DLL, which allows using WASAPI exclusive for ultra low audio latency 👀👌
