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

If did use 48 Gbits/s PAM-X, RAW (without frame headers), you could do 240 channels @ 200 Mbits/s (200 MHz), total.
240 x 200 = 48 Gbits. Headers would be equivalent to 2 pulses in time, so +2 bits per sample frame.

In this case we can calculate 240 channels +2 (frame) = 242 channels x 200 = 48.4 Gbits.
1 channel is 1 bit within a frame, so 2 bit time (single pulse) = 2 channels.

----

Frames chain link, where the new header ends the previous sample and starts a new.

----

Bandwidth is not the right measurement, instead its bit rate, or pulse rate.

I see a typo in line one of the post above (+you, If you did use). Anyhow since I was previously talking about 48 GBits/s and more if PAM-X, I will re-iterate PAM-X video:

GPU: 3840 x 2160 (4K) = 8,294,400 (8.3 million) pixels, 1 bit a pixel would be 8.3 Mbits, x refresh rate, lets say 1000 Hz (1 kHz) = 8.3 Gbits/s.
No change to pulses per bit, since pixels display 16.77+ million colours, its already direct pixel data (not encoded).

Using the same as audio (to validate): 8,300,000 channels at 1 Kbit/s = 8.3 Gbits/s.
PAM-X GPU, could also be called pixel pulse technology.

----

Would not be surprised if Nvidia decide to put their Spectrum-X (PAM-X) on a GPU.

====

The PAM level with RGB is [RGB] its self, 256^[3], the number of available values, per bit, is equal to the result. [RGBV] (if V = 256) is 256^[4].

Just so you know I will not be updating this pack very much, if at all. The DTS files are not being changed, as the files used are the last version to support 'External' universally as default.
Most newer devices will have USB Realtek and not HDA, due to the available bitrate and other features. The current HDA Realtek files work perfectly for me.

I am also looking to upgrade my Z906 from 2010 (original version), so personally I am waiting for a self controlled DTS DMAS.

----

Note the current DTS DCH pack contains the updated APO4 extension and APO4 preset (DTS:X Ultra).
The preset requires no further updates, there are essentially no files (universal).

Global processing is enabled.

----

For SPDIF multichannel, you won't get a better experience. DTS Digital Surround has a higher specification than Dolby Digital Live.
APO4 (DTS:X Ultra) processing (32 bit float) is enabled on SPDIF (pre-encoder), so enjoy the upgrade!

Also don't think of the data rate of PAM-X as oversampling, although it has the same positive effects.
Audio bandwidth is 20 Hz - 20 kHz, the data rate used is independent from bandwidth.

You can do 20 Hz - 20 kHz at 2 Mbits/s or 2 Tbits/s, the latter being the most accurate.
The slower the data rate, the more sparse the audio data is (gaps, missing).

Here is a universal audio video and data cable, either end can be connected, as the transmitter and receiver are built into the devices.
Standard up down connection, in HDMI terms that would be full audio video and data return, such as eARC.

It would be possible for a TV and a gaming console to communicate internet, in addition to audio and video.
A TV for example may have a hardwire ethernet input, which can be expanded to the console.

Technically speaking 200 MHz can record up to 100 MHz in audio bandwidth, a digital brickwall filter is used to attenuate all frequencies above 20 kHz (20 Hz - 20 kHz).
At this point the 200 MHz (200 Mbits/s PAM-X), is used to represent position data for 20 Hz - 20 kHz, and not above, increasing data accuracy.

This is why audio bandwidth is not a specification with PAM-X audio, instead its bitrate, with a specific audio bandwidth.
You also don't specify a decibel specification to bit value range, instead its speaker power and SPL.

----

Example PAM-X speaker specs (updated with PCM equivalent):

Bits: 1 (24, 48 - RGB)
Bit rate: 200 Mbits/s
Pulse rate: 200M - 400M
Response: X Hz - Y kHz
Transcoder: 60w, Max
SPL: 100 dB @ 60w

Bits: 1 (32, 64 - RGBV)
Bit rate: 200 Mbits/s
Pulse rate: 200M - 400M
Response: X Hz - Y kHz
Transcoder: 60w, Max
SPL: 100 dB @ 60w

To re-iterate.

PAM-X Audio.png

The amp is a PAM-X amp, bit value changer.
At the Windows end its a soundcard.

You can add a brickwall filter to the mixer.

====

Based on an older paper on optical internet, a single fiber can carry up to 400 TBits/s.
So bitrate is a non-issue, pulse rate and sensors are the limiting factor.

Neither USB or HDMI (or DisplayPort) can do 400 Tbits/s.

====

Take note of my video post and universal cable post above, same cable for the DMAS.
As you can see from my video post, PAM-X does 1000 Hz in less bitrate.

400 Tbits/s available and it only needs 8.3 Gbits/s (rounded up).
2000 Hz and a 0.5ms frame buffer, 1ms response.

----

7680 x 4320 (8K UHD) = 33,177,600 pixels (33.2 Mbits rounded) x 1000 = 33.2 Gbits/s.

No compression, no encoding, no binary, no power signal, easy to calculate.

In terms of video, PAM-X its self is the pixel clock, and its in bitrate not bandwidth.

1000 Hz would need 1000 FPS.
 
I actually do not know, the badge shows for me when I install DTS:X ultra, its only a shortcut so do not worry too much, it should be there though.
 
Noted. I am still using Win10 here, ultra low latency.

That's an edited image, but if only.

It seems I should refer to the method used for he DMAS, to be called [1 bit PAM-X].
Each pulse (1:1) is a bit, each pulse can represent 16,777,216 values.

This, in turn means each bit can address 16,777,216 power switches (steps).
In addition, it would be sound transmission at the speed of light.

PAM-X.png

----

If you used 2 pulses to 1 bit time (2:1), then 281,474,976,710,656 values.

----

Multilayer level, RGB as the primary, pulse to bit time the secondary.
Bit time and data rate can stay fixed, regardless of pulses.

Bits: 1 (24, 48 - RGB)
Bit rate: 200 Mbits/s
Pulse rate: 200M - 400M
Response: X Hz - Y kHz
Transcoder: 60w, Max
SPL: 100 dB @ 60w

No, the one I gave AAF is a bit newer, but there is no difference in audio.
 
Did DTS Sound Unbound app topped working for all of you or is it just me?
I reinstalled everything same results every time hope some one can help me thankyou.

I would guess Windows downloaded another driver and installed it. If your are using the provided apps, and they did not update, then check driver.
 
Pulse rate to bit value, with equal bit time, simplified illustration. For two pulses A and B, for each A there is B (A x B, A^Pulses).

Pulse Rate - Value.png

Yes it's possible to increase the value range of A (RGB), for example RGBV, still A x B (A^Pulses).
In linear transmission A is first, B second. BA -->

----

You can use pulse rate to increase bit values, or increase sample rate, or both at the same time, RAW direct.
Given a single fiber can carry up to 400 Tbits/s, the potential for resolution is massive.

----

It should be possible to produce a laser lock for security, one that uses variable colours and pulse widths.

If you use EAPO, and have used MFX, you will get that issue, since you replaced DTS with EAPO at that point.

If anyone needs assistance, I use RustDesk, no install (run as admin), message me.
I have a 10/10 reputation using RustDesk with the general public.

Most of the time I will refuse donations, so don't feel like you need to pay me.

If you update Win10 to Win11 you can also get a whole bunch of issues to fix.
