Is it possible to set the driver 'resolution' to 16-bit/44.1 kHz?

jiitee

Tril · Sep 24, 2006, 08:27 PM

jiiteepee, the ASIO inputs of all the cards supported by the kX drivers are only available at 48 kHz since the DSP works at that frequency. At least, my soundblaster card (emu10k1) works that way.

ketu, in the latest version of the drivers (3538l), you can use the ma command to
assign any DSP control to master volume. Here is a plugin to control the volume of six inputs : Vol6.da

The code of that plugin is simple :

Code:

  macs   out4,  0x0,  in4,  vol;
  macs   out5,  0x0,  in5,  vol;
  macs   out6,  0x0,  in6,  vol;
end

Register the plugin by executing it.
Load the plugin in the DSP and place it between Surrounder+ and epilog.
Open the kX console (from right-click of kX system tray icon) and type :
ma 0 Vol6 vol vol 0x7fffffff
If you want to reset the Master volume to its default usage, type the following in the kX console :
ma 0 epilog MasterL MasterR 0x7fffffff

Thank you very very much.I can use master volume now. What can i say... only serious people here...didn't expect to have so much support...once again i THANK YOU

Best regards!!1

Tril · Sep 25, 2006, 06:43 PM

It appears that the changes are reset when you restart your computer. See this thread posts 9 and 10 about this.

Following Russ suggestion, you can create a .bat file containing the command "kxctrl -ma 0 Vol6 vol vol 0x7fffffff" (without the quotes) and place it in the Windows startup folder (you can find it in "Start->Programs->Startup" if you have an english version of Windows).

Hi,

first of all, THANK YOU TRIL. You changed my life

. Because since i got a back surround loud speaker, i was searching for a solution to get my games on the computer in 6.1. Now i got it with your tool. I just set my audigy 2 (which is modded @4) to 6.1, start encoding with your tool and force Dolby Digital EX with my receiver and everything works perfect. The receiver does a really good job, it clearly seperates the back surround from left and right surround.

Now some questions. Would there be a way to optimize your tool to 6.1 and maybe for DTS (or dts es in case of 6.1)?

THX
MCX

PS: I love you

PS2: Is it normal that i'm able to hear the latency (i set it to 2ms) in some gamemenus? if i switch over to analog sound, i can't hear any latency...

Tril · Sep 27, 2006, 12:28 AM

I took a look at how Dolby Digital EX 6.1 works and it's probably possible to add it to redocneXk. I'll try to add it if you agree to test it for me (I don't have the required hardware to test it myself).

DTS encoding is not possible because no free encoder exists. Reverse engineering is illegal. There exist a free document about the specs of AC3 but there is no such document for DTS. So all free DTS decoders would be assumed to be made by reverse engineering, thus be illegal.

There is always a latency of at least 32 ms because the encoder encodes blocks of 32 ms of audio data. The latency is probably higher due to other factors that add up.

mcx · Sep 27, 2006, 08:34 AM

ok ok. yes i would test it for you

.

thanks

Tril · Sep 27, 2006, 02:28 PM

If you can manually enable Dolby Digital EX (you seem to be be saying that you can and that you are doing it) and if you are using the kX drivers, there is nothing to change in redocneXk to get a surround back channel.

If you are using the Creative drivers, i'll have to add a seventh ASIO input to the program and do the mixing of the rear surround channel in software.

Download here an example of a DSP to test the rear surrund speaker of Dolby Digital EX. Enable Dolby Digital EX on your receiver, set the volumes of Stereo Mix to 100% and start redocneXk.

If it works, you should be able to hear the sine wave coming out of your surround rear speaker. From what I've read, to add a rear surround channel by using Dolby Digital EX, you mix the rear surround channel to the surround right and surround left channels.

I can modify redocneXk and the avcodec dll to activate the flag that tells the receiver that the AC3 stream contains a rear surround channel. This would make the receiver automatically activate the EX mode. Tell me if it's necessary or not and if you want me to try to program it.

mcx · Sep 27, 2006, 04:07 PM

hi!

It would be good if you try to do it. because i don't use kx Drivers. my audigy 2 runs at audigy 4 and the configurations are much better than kx... it would be nice

thx
MCX

Tril · Sep 28, 2006, 01:19 AM

I just noticed that Dolby Digital EX support is already partially implemented in the console version of redocneXk specially made for the Creative drivers and in the GUI version. Also, if you use the kX drivers, you can mix the rear channel in the DSP.

All you need to do to get the rear channel working with Dolby Digital EX is mix the rear channel to the rear left and the right right channels and flag the receiver that it's getting a EX encoded stream.

Both versions I mentionned at the beginning of the post already have the rear center channel mixed to the rear left and rear right channel so the rear center speaker should work if you activate Dolby Digital EX manually. If you use the other version where it's not mixed, you can do it in the DSP.

Most if not all receivers have the option of manually setting the receiver in Dolby Digital EX mode so I won't put much work in getting the flagging of EX content to work for now.

Tonttu · Oct 15, 2006, 05:11 AM

Hi,

First off I'd like to thank you for your hard work, for free, to bring nice digital surround with all sound sources (especially when everywhere was said that it is not possible

.)

Now on to my problem.

I have Audigy 2 ZS Platinum Pro, Logitech Z-5500 and Creative's drivers.
When I use digital mode the bass is almost nonexistent, and this happens even without redocneXk.

At the moment I've the speakers connected with optical cable, but the problem is present even with coaxial cable.

So to sum it up: Digital bass = very weak, Analog bass = normal.

Does anyone have any suggestions how to fix this?

Thanks in advance.

Tril · Oct 15, 2006, 07:54 PM

I found some information but I'm not sure what's the cause of the problem.

Basically this changes the level display for the volume control to a "stepped" type display instead of the default "bar" display. It also changes the color of the LED when in standby mode from red to purple... how cool is that?

To toggle between the first and second skins, first set the unit to standby mode, then press Input + Effect + Settings + Mute simultaneously for 6 seconds. Once you see the LED flash for 2 seconds, you would have toggled to a new "skin". The only downside to this "second skin" is that the volume is about half as loud as the main skin's.

2. Enabling volume offset for Analog sources

Okay so you noticed Direct 6 Channel analog mode is lower in volume compared to Optical and Coaxial digital. If you want to "normalize" the level here is how you do it:

While in 6 Channel Direct mode, hold down the Mute button and start rotating the volume knob while keeping the Mute button down. Note that the display now shows "offset" values.

3. Displaying firmware version and resetting to factory settings

Set the unit to standby mode then press Input + Settings simultaneously for 6 seconds. This will display the firmware version for a few seconds and will also reset the settings to their original factory values.

4. Displaying the digital stream type/mode

Set the unit to standby mode then press Input + Effect simultaneously for 6 seconds. This will put the Control Center in "Diagnostic Mode". Now everytime you the Z-5500 is fed a digital stream (DTS, DD, etc.), it will display the stream information (format, bitrate, etc.) for 5 seconds in place of the DD or DTS logo before returning to the standard display.

2 and 3 might help you.

Verify that you are not in night mode while listening to the digital mode. I think this is some kind of compressor and it may be lowering the bass.

You can adjust the level of the speakers separately but this is supposed to be global (the same for all the inputs). Try to increase the level of the subwoofer while listening to the digital mode to hear if it raises the volume enough.

All I can say is wow.

Only the "factory default settings" part is mentioned in the manual.

Just woke up and can't test right now if they had any effect. About 7 am at the moment here.

Oh, and it seems that in digital mode the master volume, bass and treble slides in Windows volume control/Creative surround mixer do nothing, so it would seem that the "digital bass control" in Windows is at zero gain and can't be changed with the normal controls.

I don't think Z-5500 has night mode, but yes I tried to put the subwoofer volume to max, and it didn't have much effect, so it might be the cause of the "digital bass control" in Windows being default at zero gain and can't be changed with the normal controls.

All in all, thank you very much for your suggestions, I'm sure they come in handy even if they don't work in this case - the second skin is pretty cool.

I'll edit this when I have tested.

EDIT:
What the heck, now that I have the second skin the Windows/Creative master volume, bass and treble work like they should in digital mode, hurray! Thank you!

Although it seems weird that they suddenly start working with other skin, because previously I could put the master volume/bass/treble from the Windows volume control/Creative surround mixer to 100 % without any difference from 0 %.

Oh well, atleast my bass is now normal in digital mode, thank you again.

TheOtherside · Oct 16, 2006, 07:18 PM

Thank you very much for this tool!

But i've a little problem. I did exactly everything you described in your first post, (although I couldn't find AC3 Passtrough mode in Kx Mixer? Maybe because i've a newer version?

http://img107.imageshack.us/img107/8839/kxmixerdy3.jpg

But that isn't the only thing, I get the message:

Wich is weird because I managed to install the kxdrv3537-full drivers
My Soundcard is a Creative Soundblaster Audigy 2

Does anyone has a solution.

**dj_stick** · Oct 16, 2006, 08:00 PM

use drivercleaner to remove ALL aspects of the creative drivers - you don't need them (they just cause trouble)

the ac3/spdif menu with "SPDIF1" selected in that pic of yours is the AC3 Passthrough selection

Thanks that worked out great, i've now Dolby Digital turned on all the time even when listening to MP3

sweet

.

Only one more thing, I can't seem to set my delay time in the Asio control pannel, I can only choose from:

2.66 ms
5.33 ms
10.66 ms
21.33 ms
42.66 ms
and even higher values

But I can't select 32 ms wich I read was the best option, Now I selected 21.33 ms but a few pages back I readed that that wasn't a good value to set it on.

mcx · Oct 22, 2006, 01:44 PM

hi Tril,

are you working on the DD EX encoder?

Could there be a way to minimize the buffer from 32ms to something shorter?

thanks
MCX

Tril · Oct 22, 2006, 05:39 PM

I'm not working on the DD EX encoder, mainly for two reasons.

EX playback can be manually activated on most receivers.
The required routing is correctly done in the test version for the Creative drivers, it can be modified in the version with a GUI and this routing can also be done in hardware in the DSP of the kX drivers.

The buffer can not be shorter than 32 ms. DD is digitally encoded audio and the length of each block of data is 32 ms. You have to wait 32 ms for the audio buffer to fill before encoding it.

That's the shortcoming of using realtime AC3 encoding. You have to live with a delay of at least 32 ms.

yesterday, i bought the Asus P5B Deluxe... it has DTS Connect with the onboard soundchip, i will report

ViRuS2k · Oct 25, 2006, 01:55 PM

Does this work for people that have a Digital Reciver and XFI Fatality but can only connect from the XFI to the Digital Reciver VIA Spdif cable

I get 5.1 digital on movies only lol

ROBSCIX · Oct 25, 2006, 02:03 PM

Not with a X-fi. This ia for older CL cards...Audigy 2's Live's etc. Unfortunatley you will have to make due with what you have.

Tril · Oct 25, 2006, 06:22 PM

Sorry to contredict you ROBSCIX but :
- It can work on the X-Fi.
- It won't work on the SB Live because the kX drivers don't support AC3 passthru on this card and the Creative drivers don't have ASIO support.

Using an X-Fi, it's about the same as using the Creative drivers on an Audigy2. The difference is that the X-Fi works on 24 bits packed into 32 bits and the Audigy2 can work with 16 bits. Dolby Digital only works at 16 bits. To make it work on the X-Fi, you need to convert from 24 bit to 16 bits. I made a closed test with someone and it worked. This version was not ready for release.

It will work on the X-Fi in the next version of the program but I don't have the time to program it for now.

ViRuS2k · Oct 28, 2006, 03:06 PM

hmm so tri m8 your saying with the xfi cards and your updated drivers that i could then use that 5.1 on the fly decoder to get 5.1 from games though my spdif to my digital amp ?

Tril · Oct 28, 2006, 08:01 PM

Yes. I'll work on it as soon as possible.

I stand corrected, I must say I don't know alot about this plug because I don't use it. I would say now it doesn't need KX? What I meant is KX doesn't work on the X-fi and last time I looked this plug needed KX to work. I guess things have changed?

No, kX was never really a requirement. It was always more about the abilty to record each channel using a real ASIO driver (and in the correct format), and the ability of the driver to do AC3 passthru (do both things at the same time).

ViRuS2k · Oct 29, 2006, 10:32 PM

so i guess no KX in the future and without them i cant use that on the fly 5.1 decoder for games with my xfi and spdif out.

Using an X-Fi, it's about the same as using the Creative drivers on an Audigy2. The difference is that the X-Fi works on 24 bits packed into 32 bits and the Audigy2 can work with 16 bits. Dolby Digital only works at 16 bits. To make it work on the X-Fi, you need to convert from 24 bit to 16 bits. I made a closed test with someone and it worked. This version was not ready for release. It will work on the X-Fi in the next version of the program but I don't have the time to program it for now.

I would say now it doesn't need KX? What I meant is KX doesn't work on the X-fi and last time I looked this plug needed KX to work. I guess things have changed?
