How to Redirect 5.1, 7.1 to SPDIF [DTS-Dolby] - All Apps

[Ferather]

Same as the older X-FI, capture PCM from Speakers > encode to DTS > redirect to SPDIF > SPDIF out. You could have enabled 'Stereo Mix', then enabled 'listen to' then mute it for 'always on'.
When I had the X-FI there was an additional Creative service for the encoding and redirect, which used up to 10% CPU (at the time), I had an 8 core CPU when tested.

Another way to achieve Speaker to SPDIF redirect, is to install Virtual Audio Cable (VAC), then setup the playback as Speakers, and capture to 6 channels.
Then set the capture to 'listen to' SPDIF (where SPDIF has the encoder on it), it will redirect Speakers to SPDIF (6ch), then DTS out.

If you get the full version of Virtual Audio Cable, you can set it up the same way as Creative. As above, if you need help let me know.

Speakers (VAC, 5.1) > VAC Capture, listen to enabled (5.1) > SPDIF (DTS 5.1, encoder) > DTS 5.1

----====----

You will need to right click and run the config panel app as admin, and enable speaker pin (tick box). Speaker and capture should be max 6 channels 24bit, ideally 48k.

got it all working i am not sure if there is a delay while gaming. movies are no delay
here is all my settings maybe you can check if all is correct in the vac control panel

dont know why it shows 8 channels

thanks again

I think the 'MS per' is the ms latency per instance, 3ms I would guess, that's perfectly fine. Also try max NC 6, see if that makes it 6 (top left corner).

all is fine now. nc 6 was the setting i overlooked
thank you for helping me

VAC will also accept Equalizer APO, if you want to add an SFX upmixer, see here.

 

[Ferather]

A small side note, VAC seems to have its own channel mixing feature that appears to disable the Windows one.
The 7.1 to 5.1 with virtual side downmix trick does not seem to work with VAC, at this time.

The first time I tried it, side was redirected to front, after some changes just blank.

 

[Ferather]

When setup and running, you can either use VAC Speakers (redirect) permanently, or for certain apps-games.

fx sound can be used instead of loopbeaudio if u cant afford that to send 5.1 audio to games if the game is haveing issues with these drivers the only game i had issues with before useing fxsound was overwatch 2 but after installing fxsound on the microsoft store for free it outputted full 5.1 surround sound to my system aswell as made my dolby digital plus eq move so it was still useing the drivers i turned fxsound off so it diddnt apply any enhancements as iv set my eq the way i like it for my system 10/10 would reccomend loveing this for gameing (posted twice just incase some ppl dont see this post but see the other one )

 

[Ferather]

Note, this fix will not work on app and games that output the maximum number of channels set by the device, but only populate certain channels with audio.
An example is a web browser YouTube and Audacity, we can see all channels are in use, but stereo only populates left-right.

Below I am using the SPDIF output directly (no VAC redirect), all channels are in use, correctly.



Most upmixers will detect more than 2 channels, do nothing.

which fix are u speaking of?

[nicegirl05]

thought i would update iv found fx sound to be paired best with dolby digital plus home theater hdmi/spdif useing dolbys eq adds too much processing to the mixes that i cant stand but if i use dolby home theater v4 its 20 times worse so i tryed v4 with fxsound still sucked thinking of trying to use dts my optical usb adapter can support dts just my speakers dont support dts dolby only so idk if itll work

I am doing the same to upgrade DTS Interactive into essentially DTS:X Interactive, by adding additional DTS:X processing prior to encoding.

well that work on a dolby atmos 5.1 soundbar i do have true rear speakers but no support for dts and dolbys drivers for windows kinda suck

 

[Ferather]

No it seems you can only receive Dolby Digital (from what you said). I won't comment on Dolby Digital sound quality, and also Windows :s

danmm ok at least fxsound makes it sound perfect but i dont like the fact i need a extra application just to make it sound on par of quality to hdmi do yk why that is?

HDMI will be outputting multichannel PCM, Dolby Digital will input multichannel PCM, then encode and compress it to [640 kbps - 16 bit 48khz 6 channels], then output.
Now lets say you set HDMI to 24 bit 48khz 6 channels, as mentioned that would be uncompressed PCM, at 6.912 mbps (6912 kbps).

Not only will Dolby Digital compress the audio, in this case it would also go from 24bit to 16bit. If you sent 192khz, you will get 48khz also, with HDMI it stays at 192khz.

Conclusion: Dolby is nerfing your audio.

i hate it here i can only use dolby iv tryed useing the viper4windows some of the dts ones asus sonic drivers at least i can make it better but sad i have to but my optical port aswell as system dose fully support 32bit over optical iv found is out thru looking at media player classics output settings the main issue i have is when it comes to how loud music is not compression everythang sounds just as rich as hdmi but its not as detailed and loud unless i use a eq with a eq it sounds sometimes better than hdmi or at least compairable this could be due to fxsound also supporting 24bit audio

 

[Ferather]

Yes its a shame in this case, DTS is the better pick guaranteed.

turns out im not useing dolbys or dts ture audio codecs media player classic has been translateing theme to
dolby digital/plus/ a IEEE float 5.1
anythang atmos/truehd is pcm 7.1
anythang dts is pcm 5.1
anythang dtsx is pcm 7.1
all 32bit hz depends on the actual file iv found but my optical connection can support up to 192.0khz
(afterthought) i just thought about this but is it the drivers that are translateing my music or is it media player classic

 

[Ferather]

Media player will output what you said, but the Windows audio system/device will output the devices selected format.
In terms of quality and accuracy you seem to have the right output settings.

ok good shit thank you so much im disabled and dont have a job at the moment so i use surround sound as a way to coap with being stuck in the house i love the way it all works and the history around it youv been a huge help i highly appreacte you

 

[Ferather]

I'm doing the same, 32 bit float, although I set 48khz high quality (oversamples I think), PCM output, it then flows through Windows audio partially as 32bit float, finally encoded to DTS Interactive.

So lets say I playback Dolby TrueHD or DTS-HD Master Audio, its decoded to 32 bit float 48k HQ PCM, then output as DTS Interactive.

also have to say have u tryed ther fxsound method i spoke of on your system before? on the forms some ppl say they love it some say they cant use it i want to reccomend it but it seems ify on support

also for me dose that mean i am actually getting a true dolby digital signle ? because in that case how is it live encoded i can play games besides ones with object baced surround without fxsound just fine

 

[Ferather]

I have not tried it no. Currently there is no reason for me to use it, but I have nothing against others using fxsound.
You are getting lossless to lossless up to the encoder, the only loss is the encoder its self.

You do gain the benefit of digital passthrough, which reduces hardware influence on the audio.

thank you letting me know i must ask whare did you learn as much as you know iv been scouring the internet on terms of months now and havent found alot of documintation on this kinda thang besides the actual encoders themeselfs

but if u find somethang u feel could give better performance please reach out iv described my system needs to a t

 

[Ferather]

Also on a side note, 2 channel max MP3 is 320 kbps, so 6 channels would be 960kbps, DTS Interactive is 1509 kbps.
Would you notice the difference between CD and DTS Interactive, maybe, probably not.
