POSITIONAL AUDIO WORKS BUT CAN'T FIGURE OUT WHETHER EAX/A3D IS WORKING

BEENNath58 commented 4 years ago

IN GAMES LIKE GTA VICE CITY, GTA 3,SAN ANDREAS, I INSTALLED THE PROGRAM AND USED A DIFFERENT HRTF FOR THE GAMES. THE HRTF WORKS WELL AND I CAN HEAR POSITIONAL AUDIO,BUT I CAN'T FIGURE OUT WHETHER EAX IS ON/OFF. BECAUSE THESE GAMES HAVE OPTION TO TURN OFF EAX AND WHEN I TURN IT OFF AND USE D3DSOUND,I GET THE SAME SOUND.

IS THERE ANY WAY I CAN FIND IF EAX EFFECTS ARE WORKING.

IN CASE OF A3D,1.0 I GET THE SAME KIND OF SOUND AS I WILL GET IN BOTH EAX OFF/ON.SO I CANT REALLY UNDERSTAND HOW TO UNDERSTAND THE EAX/A3D EFFECTS IN GAME.

THE GAMES HAVE THE SIMILAR PROBLEMS WITH THE BUILT-IN HRTF TOO. AND I ALSO TESTED OUT FALLOUT NV, FEAR, FAR CRY TOO

Didn't your mum teach you anything about caps locks and the internet? Then, GTA 3 has a selection for eax, but san andreas does not. And they support higher versions than the ones working here.

And A3D requires the right wrappers instead, this is only one little part of the possible problems.

I wrote with caps lock off but while writing FEAR and selecting the shift option on mobile keyboard,the text got cap locked.

GTA 3 has options for eax, eax 3, dsound3d, my question was how should i understand if eax was activated after selecting eax option. Secondly A3D 1.0 was supported by DSOAL in GTA 3 but I couldn't find any difference between DSOUND3D, EAX or A3D. DSOAL supports EAX, A3D, is true, but i dont get any difference in turning off EAX or A3DD.

San Andreas supports EAX, EAX2, EAX3, EAX4 and the game provides proper HRTF too.

Dsound3D features are working. How shall I know if EAX and A3D features are working? That was my question.

DSOAL is literally Directsound-OpenAL. There's no A3D involved. If you want that try to use this.

As for the rest, if I'm understanding this right, I may suggest replacing "CAN'T FIGURE OUT WHETHER" with "enabling doesn't make a difference".

You are right, Enabling doesn't make a difference . I installed Alchemy with restriction remover for helping in this matter but still i couldn't find out a difference. And for A3D 1.0, it gave me same sound as eax with DSOAL, but A3D 2.0 would crash. I don't know how this worked but lets leave it. However that piece of software: a3d live and a3d driver from pcgaming site didn't install on my Windows 10 PC. I would get a crash in the setup with the message "Install failed" for both of them.

This is absurd as i execute them with admin privileges, and they don't install.

However I now got A3D to work by a software named A3D-Alchemy

I also find DSOAL supports a3d 1.0,not 2.0. Every a3d 1.0 game works for me.

Even the youtuber has videos of a3d on dsoal and has even found out bugs in its emulation

To see if EAX is actually used by a game run it with DSOAL and these environment variables set:

DSOAL_LOGLEVEL=3
DSOAL_LOGFILE=1_dsoal_log.txt

Warning: The DSOAL log file can get really huge: Hundreds of megabytes within minutes so don't play for too long with the environment variable set or make sure you have enough disk space and a capable text viewer.

This creates 1_dsoal_log.txt next to a game's binary. Open it and search for EAX and you should see the EAX calls a game makes. I've seen some games claiming to have EAX support but not really doing anything with EAX although maybe I just didn't test them enough.

From my understanding the logfile can also be used to see if a game actually uses the DS3D API for positional audio. Some games apparently use dsound.dll but only use DSBuffer_SetPan calls to generate positional audio, i.e. positional audio is only 2D. Other games apparantly use internal mixing and only use dsound.dll for the output of prerendered buffers. Usually the log file contains only calls dealing with buffers. To check if a game actually uses DS3D for positional audio I search for DSPrimary3D_SetPosition but I don't know if there are cases where this DS3D call doesn't appear in the log but the game still uses DS3D.

The last paragraph only stems from my observations, @kcat would need to confirm my interpretations are correct.
