Making Audio Enhancers Work on Windows

[Jayce]

You did the LFX delete properly. Try redo the delete and then click refresh on top.
Which product did you use to enable DD encode? Dolby Home Theater V4? Dolby Digital Plus Home Theater?
Still this technique might reduce the delay by usually at most 10ms.

Would deleting the LFX properly also fix the delay when using Dolby Atmos for gaming with a soundbar HDMI?

Dolby Atmos for Gaming uses SFX, and all processing is done on that SFX. Disabling that SFX = Disabling Atmos for Gaming.
Any audio processing software will cause latency. You want minimum latency = remove any and all audio processing software.

I don't think I have any processing software other than Dolby Atmos for gaming app.

Then your latency is as minimum as it can on the PC side. Check the soundbar if there is any audio enhancers enabled.

Is realtek audio console a processing software? I don't need it anymore since I use a soundbar.

My soundbar has Truvolume setting. Night mode off. Ecopower is on

Ok, my bad. I had to hit "Apply Effect and Processing Mode Configs".
Yes, it seems to be better now and the experience has improved. Not much, but made me happier. Every bit counts
I used Dolby Digital Plus Home Theater (HDMI/SPDIF). Any better product to improve the latency? (I have not installed any Audio Enhancer app, btw).

Truvolume WILL cause latency. realtek audio console is not audio processing.

I have an issue applying modern APOs on my Sound Blaster Omni.
This is my stock APO on the SPDIF out endpoint.

[Notes]
Default Omni SPDIF

As I need Dolby Digital Live, I cannot replace the GFX. I can only replace the LFX section GUID with older APOs, locking me in using a single APO at a time.
Trying to put anything in SFX, MFX, EFX does not apply; no APO gets loaded; clearing LFX and GFX does not make any difference.
I would like to use APO such as Dolby Atmos, but I cannot apply those. Also I was previously could use composite APOs on Realtek, but cannot on the Omni.
Does anyone know how to allow usage of modern SFX, MFX, EFX on such devices?

In the original driver package of this model, only GFX and LFX are used in INF, but in Creative's APO (Post-Processing Library) SFX, MFX and EFX values are also present.

In the original driver package of this model, only GFX and LFX are used in INF, but in Creative's APO (Post-Processing Library) SFX, MFX and EFX values are also present.

It appears that the driver itself is limited.
I did a few tests with stock Windows drivers, different APOs are applied, but SFX, MFX and EFX values do not work, thus appearing that the limitation is on the driver itself.
Still, I was able to apply Dolby Atmos APO. I kept the Creative GFX, so that Dolby Digital Live support remain, and moved contents of Dolby Atmos from SFX to LFX.
Creative audio effects are performed on the GFX, compared to Dolby APOs, where audio processing is done in LFX/SFX level. Thus now I have both Dolby Atmos APO effects along with Creative effects working together. That is the most I can do.
Still, I miss using composite SFX, where I was able to mix Dolby and SRS.

Too bad I don't have any equivalent hardware at hand. If not, I could modify the driver, include SFX, MFX and EFX Composite values and test on a reinstall.

Anybody ever seen Super X-Fi mod? I think it's the best option for 3D headphone surround.

hi, im fairly new to apo, i have everything working but i dont want my audio enhancements to apply to my realtek digital output. i only want it applied to my speakers output. Essentially how do i apply product settings to one single endpoint?

You select the speaker endpoint then you use product config tool.

 

[nikownzyu]

I do that but it seems to to think my speakers and realtek output are the same thing whenever i apply it to just one of them it does both of them

OK. That's strange. Post a screenshot of FX Configurator.

I've been using Apo driver for a long time with dts connect and asus xonar u7 for 5.1 sound, works great.
But it's unclear to me, can I use any other enhancements along with it? I would like to use equalizer APO for room correction, or really any form or eq.
But as soon as I install eq apo and restart pc, dts interactive from my soundcard formats is lost.
I tried to install as SFX/EFX but its the same. Can someone help?

Hey people, i recently went back to Windows 10 LTSC (1809) and as soon as i apply APO effects (in this case Nvidia HMDI audio Dolby Digital Plus) the volume on the HDMI audio device always resets to 100% after reboot (it doesn't remember volume level prior to reboot), this issue was not present on windows 1909 onwards, disabling exclusive control did not make any difference. Btw i'm using the latest APO.
Any clue on how to fix this ?
