The first 3d audio post

ArconX

Well, let me be the first to post about the 3d audio acc.

It works (kinde ).

Running BF42, you hear for the first few seconds sound but with a bit of distoring into it. After those few second the sounds gets more distored up to the point that it's not sound anymore.

While flying a place, i noticed that after a few min, the sound of the engine returned (not perfect, but there was sound that you can recognice).

Software playback had no problems ofcourse.

I tried the same under Morrowind, and i noticed the sound had less problems, but still distorted, but not so bad like under BF42 (ran it only for about 4 min testing the 3d sound).

Sorry if it's not very detailed, but i'm not a audio expert, so i can only tell what i hear. I can't guess on the problem...

kuja

Yah same for me. Sounds are either missing or badly distorted, so I turned it off for now.

One game that it really doesn't work in is OpFlashpoint

inteks

same here in ut2003 !!!

what is the kind of distortion?
a pitch shift? cracking? noise?..

/Eugene

kuja

Definitely pitch shifting, plus many sounds are simply not audible. The missing sounds may be a config issue on my end because I only have headphones with front left/right enabled in the DSP but it set to 5.1 in Windows Audio.

ArconX

Nowp, it's not you setup, it's identical to what i hear ( 5.1 Audio on in KX ).

TWidXugA

I've got a 4.1 speaker config, and am testing it with games such as morrowind,
gothic 2 etc...
i noticed strange pitchshifting to the point of distortion only with certain sounds on gameplay, and most of the times are the same sounds (samples) of the game that make it happen.
As for missing sounds, it seems i'm sometimes lacking a center channel instead of it bein redirected to my only 2 front speakers, even if I configure the games to 4 speaker setup, this is variable though. (of course I have the surrounder set to 4 speakers).
also experienced (and this happened 1 time only) a "doppler go crazy" thing for 4 or 5 seconds...
I just hope any of this info helps in any way!



Thanks 1 more time kx people!!

Eugene Gavrilov

there's an updated version of 3534 available (non-official release)
it might fix certain problems with Doppler as well as muted sounds

let me know if it fixes some of the issues

http://kx.maincore.nl/beta/kx3534e1.rar

(copy kx.sys to windows\system32\drivers folder and reboot)

/Eugene

p.s.
use WinRar 3.x

kuja

I lost all sounds except for a single ambient with that update

TWidXugA

Used the update
and nothing... I still get pitchshifting in strange ways, like when a character in gothic 2 is speaking and I turn around quickly:
it all gets pitchshifted to a higher or lower frequecy (sometimes higher, sometimes lower).
I haven't notice missing sounds though... but the testings has just begun.

Hope to help in anyway...


Thanks 1 more time Eugene!

Eugene Gavrilov

perhaps we need to find a 3-D tool to verify / reproduce audio bugs...
does anybody have EAX2 SDK installed? or, probably, Microsoft DirectX SDK?.. or at least RMAA3D?

I'll try to create a test suite -- but this might take some time...

/Eugene

Details follow after installing the e1-driver

HumanRes

ok, here some results.

dxdiag-issue is still there.

UT-issue (pitch shift / disorted / loud sounds with directsound enabled) is not gone. But i figured out thatit has something to do with speakers setup. I had 5.1 copy mode, and switched now to 5.1 surround on. So i recognized that the "missing" sounds i described are actually not missing, but come out from the rear speakers now. But some sounds are still disorted (loud parts). In my opinion, the separation between front and rear is very absolute, i mean the sound directly switches from front to rear. I don't know if this is a feature or a bug, but i think it should fade out or should be there on front and rear. So, in 2.1 setup with surround enabled i hear nearly all sounds on my headphones, but as already said some are very loud, and others can't be heard nearly.

Rightmark 3D Sound Subjective Test
Everything sound good. 5.1 surround on is fine as well as 2.1 surround on. And this in ds software, ds hardware and ds hardware eax2 mode.

Well i watched the debugview output while running UT and Rightmark CPU test.

Eugene_: if you need the complete / more logs, let me know where to send it (>50K).

the RM3D-log has some entries

don't know if this is relevant.

3534e2 is out -- check it (and post any feedback to that thread, too)

http://www.hardwareheaven.com/showthre...threadid=23464

at least, it fixes a doppler issue in some games (such as Morrorwind)
