DTS DCH Driver for Realtek HDA [DTS:X APO4 + DTS Interactive]

[Ferather]

HDMI, eARC and SPDIF are all limited by HDA which is common at ~37mbps, that includes DisplayPort.

just kinda dumb i mean your using a full hdmi cable and port for audio only you think it be at least 18gbps lol

 

[Ferather]

Unfortunately not.

 

[emanresu]

Hmm.. but if Windows x86 can handle (at least) 128GB RAM (with lil' tweakerz) - and HDA goes all the way back..
Always wondered why B.G. went x86 -> x64.
32bit Vs 64bit.. but is really x86 32bit (limited)? Or did the elderly wizer wissards foresee a Loudness War early on?

i feel like you may be confuseing audio bit depth and memory register bit architecture

 

[Ferather]

Yes he is, hes wonderful in his own way, 64bit audio is OTT. Regardless, yes we are still limited by HDA.

I have a question for you emanresu, if 24bit 48k is lossless, what does 32bit 96k do?

 

[emanresu]

32bit isn't "lossless" either.
I've broken 192khz32bit.
Just saying. A lot of bass is a lot of bass.
You should remember, I've told you alreadeeh

And DTS HD Master/DTS X has HP filter..
Then it's NOT lossless.

We tried on a good Mastering friend of mine's audio track. DTS HD Ma - Best Quality - just made it sucky. So don't get too in-nerded on false DTS or Dolby bribery.

 

[Ferather]

You could do it in various formats including FLAC or PCM, since encoded formats end up as PCM in the end.

If it was PCM, then you could side-by-side a visual wave test to see the difference between 24bit @ 48k and 32bit @ 96k.
That way you should be able to visibly see if there is a difference between the two, and compared to an original.

In terms of a DAC and equipment, you could add a lot of variables.

 

[emanresu]

Yes many variables indeed.
But I know that 16bit 44.1 with correct forcing and recording / playback (AudaCity - perfect loop) will give you full 3D. 24bit & 32bit & 64bit is like halfhandicapped alternatives to not having analog gear or recording in ONE bitdepth from beginning to end.

Windows is not a fan of 44.1 - even though playback device says 44.1 - it's probably not.
Spotify -> Vac (44.1 16) -> AudaCity MME input that Vac with transport on/overdub off and then your playback device in also 44.16.

Tldr: WASAPI layers a dimensional coating that just sucks. True audio can be looped.
WASAPI CAN NOT.

 

[Ferather]

Yes indeed, its a good discussion, when we include human limits and hardware ability. Plus games, and encoded audio will need to be updated to 32bit and 96k +.
If you try to turn a 24bit 48k file or audio source into 32bit 96k +, it should be no different from the 24bit 48k file, but now larger.

If I remember correctly the Z906 plays back 24/96 DTS Surround, but unfortunately even back then, it did not take off.

Side note, 32bit will also increase bandwidth requirements on HDA.
There is also high and low quality re-sampling, at the same rate.

 

[emanresu]

Yes, but don't listen to music in 48khz.. or 96khz.. or any 48 multiple. It just is not the same - when the source is RECORDED in 44.1 [CD standard]. Which pretty much all music is.
Sorry.

I told you about the PAL SpeedUp effect©®™
If that was intentional towards us Europeans.
What do you think 44.1 kHz -> 48 kHz is?
It's like we are the Jankees' experiment.
First our TV broadcasts and movies are played back too fast and too high-pitched (2h USA NTSC equals 1h55min EU PAL). ADHD?
Then our 44.1 kHz RHYTHMICAL music is slowed down when converted to 48 kHz (* or any of it's multiples - there seems to be ONE software brand that can handle it - and it ain't fucking SoX nor R8Brain). And now Windows by standard is 48 kHz ( since when? ) and TV / DVD (and it's derivations). Which is SLOWED down, IF original recording was 44.1 kHz. The effect is that we get hyper by regular TV broadcasts. When we listen to music in our Mobile Phones we probably get 44.1 kHz (Spotify App?), which makes us perceivable to the (Swedish) correct Takt and the whole Rytm - which is all the different Takt together.
This is while you are commuting to derp work, or from it. Enjoying nature? Play something soothing or pause the digitalaries.
If 48 kHz (YouTube - not sure about YouTube Music) - then I hope they did the conversion correct... Now you can finally relax in front of your PC or TV. But it's not the artist's version (presumably 44.1 kHz since Spotify et. al. kinda requires it?). So you finally soothed your converted NTSC - PAL standard ADHD with yet another misconversion. Congrats.

I roll 44.1 (or multiples thru my whole music chain) - when listening to Spotify. This is why I will succeed. Not sure you guys actually can that when you can't hear music as it is intended. But now you know the problem. Now you can solve it.

And Ferather - I know you are the theoretical speccs guy. It takes its man. But I am the one breaking them. That takes a psycho.

And it's the Xinaman trying to fuck us in modern times. Allegedly he told P*tin that either you try take Europe, or I will. So don't trust anything yellow basically.
/rant over

You can have the Creative X-Fi output DTS 44.1 or 88.2 kHz. Start by that before getting lost in translation. Please

The German Nas Zen knew their HipHop / Beastie Boys. And they liked stuff analog.
Lebensraum and such.

Now we have the N'vidia (formerly nVidia) boss talking to a midget hologram (even more-) Meesiks-version of himself thru Reptoidberg©®™ MetaVerse. I hope they both go to hell at the same time. Which is really soon.

Here you are, courtesy of substantial Windows XP testing by Koreative Creans. Note they don't (want to?) give XP x64 the same support. But I have found a way to enable x86 to 128GB

And Windows and DRM©®™ for WHQL.
That Ego-gene is really strong once the (hwite) guy gets to the top of the fake pyramid of schemes.

Like the guy who made the first unofficial (?) DTS encoder said;
"Don't use this for commercial purposes.
I will know."

 

[Ferather]

I feel like maybe I offended you, not intended. I was just pointing out 32bit and above 48k is not yet an industry standard, and its used rarely. Not saying its worse, per say.
Blue ray certainly has the ability to store large PCM files, but I don't think the gain out weights the file size and bitrate requirements.

This is the reason why 64 bit audio does not exist, and probably never will.
Most headphones don't do above 48k.

SD: 16bit 44.1k | HD: 24bit 48k | UHD: 32bit 88.2k [??].

 

[emanresu]

64bit audio did exist on Win x86 according to an equally old plugin. This you also know already

And no, you didn't offend me.
It's just that re-sampling seldom works.
Even the Creative guys pointed out that this is an issue post-WinXP.
According to Russian sources their kernel driver is the best sounding, WinXP (x86?).
I'm just trying to get you on with what went wrong so you don't thwart yourself and others on the ultimate audio experience. You can try patching what is already wrong, but why?

 

[Ferather]

Yes, that's why games, music and encoded audio would need to support and be 32bit and above 48k, Dolby and DTS formats do support up to 192k, but not 32bit.
Everything you steam, nearly all games (probably) and encoded formats will be 24bit max, and not likely much higher than 48k.

Personally, I have only seen 32bit in analogue cases (DAC's), neither SPDIF or HDMI support 32bit PCM.
You might be able to get 32bit out via USB, but still only in analogue cases.

 

[emanresu]

I shall see what I can do with my Audigy 2 ZS, kX Driver and so.. tried to force it onto the Auz HD and USB EMU 0404 - they didn't accept the treat. Thank Lawd for Safe Mode.

 

[Ferather]

Lol, dont crash the computer too much, if you find a 64bit PCM file I will indeed be very shocked.

 

[emanresu]

Spoof Appx to roll WinXP x86 - then I'm out and over. Might have some tools for that. Or spoof Win11 (de facto x64) to partially believe that it is WinXP x86.. would it drop the Forced Sample Rate Switchery and the DRM-WHQL nonsense?

AudaCity can save in .wav 64-bit?

But can't record directly into it..
If that's what you also meant ✓

 

[Ferather]

If it supports, RF64, cant remember, else stick with 32 bit float you will be fine.

 

[emanresu]

And I busted 770dB headroom.
Lol

 

[ajf64]

770db and your head didn't explode lol

 

[emanresu]

Heheh. I have a pic of Top Peak dB that made 100+ without the plugin showing red/error. And I once did ~272 dB +, but my figgity ADHD managed to click-reset the same plugin.

* The plugin being the dB analyser, last in the chain.

Also I did -28dB Top Peak and still had more than loud audio once. Somehow I'm never content and don't document very well.

 

[Ferather]

Well if you can prove 32bit is worth the price (hardware) and file size, and also get HDA updated as standard so it can do more than 6 x 192k @ 32bit, I am all ears (pun intended).
If I side-by-side 32bit analogue and 24 bit SPDIF (where SPDIF has lossy DTS encoding), I still find SPDIF is better, although the 32bit DAC's are of equal volume.

Some people can mistake volume for audio quality at times. If an encoder increased bass range volume but lost 2% quality, is the bass better?

DTS usually is "louder" on my Z5500 compared to Dolby PL2 and alike.
Sharper.

I am scouring old Creative X-Fi YouPAX / PAX drivers and trying to get them to work on latest Windows 11 x64.

There are interesting .inf's that describe what happens when DTS is encoded / decoded. What the "new" EQ settings are, and so forth.
I believe the DTS sharpness comes from 31 Hz to 30 kHz range, instead of 30 Hz to 20 kHz range. 9.999 kHz later..

Might spoof OS and give it a spin. Sometimes you can install the latest, working driver and then "dumb down", i.e. install a tad older driver on top of the newer one, and then progress with even older drivers, step by step - and they can work, in this stepping stone process, all the way back. Especially true for Realtek.. :3

Dat GameSpirit.

 

[Ferather]

Higher bitrate, 1536 max vs 640. Dolby is also 16/48k, DTS 24/48k.

 

[ajf64]

i honestly cant tell a difference between 24 and 32 bit on my audigy 2 zs platinum pro its what made me stop using it crazy just how long that card as held up
