It can output bitperfect streams without ASIO, so why enable it?


Because it sounds better :p If you output from Winamp, Foobar2000, etc., using DirectSound you're routing through all the Windows sound architecture crap. It's a WAY more direct signal going through ASIO so it sounds better in various ways.

And the Support website. Google is your friend!

I'm assuming Upmix is essentially resampling to 96kHz or something to that effect. Sounds cool actually, i'm wondering if it genuinely makes the games' sound / music sound better.


Yeah, I'veen been digging around google looking for answers and haven't come up with any answers, but thanks for all your suggestions and help!

Not true as far as I know. If the card can output a bitperfect signal without ASIO then there is no scientific reason I have head that would result in better sound.

Also, the fact that can output a bitperfect signal without ASIO suggests that it can bypass the Windows audio system (kmixer) without employing ASIO.

I can output a bitperfect signal from any software as long as things are setup correctly and the volume setting is maxed. I have tested this using DTS encoded wave files in Itunes and many other applications. If the DTS signal is passed correctly that indicates that there is absolutely no change in the digital data stream from the source to the output. If any changes are made to the DTS signal then the decoder would not be able to process it.

I stopped using ASIO when I got this card and figured out the bitperfect settings as there is no reason for it.

It's also great to have bitperfect and not worry about what application you are using.


p.s. I'm very familiar with the mangling effect Windows can create with lousy soundcards. I spent a long time figuring out why the digital output of my original SB Audigy sounded like garbage. The infamous DTS test is the only test I trust other than my ears. Very easy to test if the output is being mangled, and the Auzentech doesn't mangle the output when setup correctly.

Hmm. Interesting. I shall have to test this and do some research and testing of my own

Thanks for the info that's really surprising / enlightening -- if you're right that is

My main question or rebuttal would be that, doesn't WDM architecture resample all output by default? I'm pretty sure it does.


EDIT: Good sig statement. It's true

It's the Upmix option right under Upmix Mode in Game Mode (see pic). That option is not available in Entertainment Mode and not sure what it does exactly.

Enabling multichannel upmix
If you are using multichannel speakers, you can use CMSS-3DSurround to upmix stereo sources into surround sound of up to 7.1 channels.

To upmix stereo sources
Click the CMSS-3D tab

Select the CMSS-3DSurround check box.

Click the Upmix box, and select the On or Auto option.

Click the Stereo Xpand option to expand stereo sound into multichannel surround sound.

OR

Click the Stereo Surround option to play back stereo sound from each speaker pair, and to redirect center-panned sounds into the Front Center and Rear Center speakers.

Drag the Stereo Envelopment slider up or down to adjust the upmix balance between front and surround speakers.
For the most compelling upmix effect, drag the slider to its middle position, or click the arrow icon to revert to the default setting.

Note

The multichannel upmix depends on your speaker hardware and your speaker settings. For example, if you want to upmix to 5.1 channels, make sure you have connected 5.1-channel speakers to your audio device, and have selected the 5.1 speakers option in your speaker settings setup.

The Stereo Xpand and Stereo Surround effects are available only in multichannel speaker configurations.

Tip

If you have a 4-speaker system, you an also enable CMSS-3DVirtual to enjoy even more realist gaming.

Not necessarily. The first time I read about people getting bitperfect output without ASIO or KS was with some USB sound cards, and some poeple who found soundcards and setting that would work with software that had no ASIO or KS options (eg. Windows Media Center Edition, and Itunes).

I've included a screen cap I took the last time this came up with this card.

Note that source has to be at 44.1 in the settings screens and bitmatched has to be checked on the other tab in the settings screens (assuming 44.1 source material). I don't know if all the inputs have to be muted, but I did notice that I lose bitperfect when the digital input is not muted. Also the volume must be maxed for the master volume, and the volume must be maxed in the application. In Itunes if I nudge the volume anwhere down from full... boom, bitperfect is gone and the DTS file will start playing as static.

Now I'm really confused. After reading that I need ASIO output in winamp now ASIO is not need for bitperfect output?
