as far as CMSS, honestly I've never played with headphone mode (didn't evnenknow the x-fi could do such a thing, I just ignore CMSS entirely since all of the previous creative boards its just like a crappier version of Pro Logic (2.0/2.1 -> 5.1/7.1 (which sounds like crap even on Dolby systems)), the headphone mode may or may not sound better, but my question is, why aren't you using EAX acceleration for positional audio, and setting it to stereo? (thats just what I've found to work the best, I'll have to play around with CMSS Headphone realizing its a feature on X-Fi that I did miss)

CMSS3D isnt just a spatializer though it does that when used on stereo normal source like music. As far as I have understood, what it does is hijact the hardware 3D acceleration with positional information and try to "binauralise" it though it isnt perfect. So for some folk it works, for others not so well. IIRC it isnt even Creative's own invention, but comes from other soundcard company that they bought which utilised this technology on their cards for surround sound without relying on multiple speakers? It is completely different from old CMSS which is just a spatializer. To use normal CMSS3D (which doesnt work well with with headphones cuz its for normal stereo speakers), you have to set your settings in Audio Console to Speakers, and for CMSS3D Headphone set for headphones (which again doesnt work well with speakers).

And again, EAX does not do 3D audio, (thought it does help) it processes enviromental effects, how sound reflects on different enviroments like echoes etc... and CMSS3D and EAX work together with each other perfectly.

EAX is an add-on for DirectSound3D, which deals with 3D audio and whatnot, but you're right, in that it isn't alone in doing 3D audio

as far as "creative bought it out", thats EAX you're thinking of, and its only part of it, in like the year 2000 Creative bought the bankrupted company Aureal, and merged A3D technology into EAX, and has been developing from that point ever since (its gone through a lot of updates and changes since 2000)

I guess im mixed it with EAX.

My XMOD doesnt have EAX i think...how useful is EAX ?

does it improve the Sound quality noticeabily?
post #20 of 46
Isnt Xmod based on Audigy or Live! cards? They had support for first versions of EAX. It doesnt improve "quality", but immersion by making sound behave much more realistically, like how the sounds sound like in metal corridors or how the wall impacts the sound between the sound source and the listener etc... They can also be simulated in software, (and some soundcards do offer software emulation of EAX) but creatuve cards do EAX on hardware with barely any impact on perfomance.

XMOD is the first product to take-out the X-fi technology of the computer.

it is a soundcard + avg. DAC + sound enhancer....

it has X-fi crystallizer + CMSS 3-D but NO EAX.

i bought as it was selling damn cheap...much better than laptops soundcard ..but doesnt satisfy a head-fi member totally.

It's stll more than just an eq. You can't analyse it by looking at a sine wave because there are no dynamics in it to enhance. A test tone will not trigger any enhancements except for the eq.

Battlefield 2142 with cmss3d enabled headphone effect sound pretty good. Except for the degradation in sound quality, the positional effects were very good. Better than any "5.1" gaming headphones that really are just marketing.

EAX is just the environmental effects. It doesn't handle anything stereo wise.

"can't compare a dedicated DSP and a general processor", true, but you really want to argue (uphill) that the Creative chip can magically fix ultra-compressed content and turn it into lossless/the original signal, my point in saying that is even in systems with hardware acceleration (like a ProTools HD system, thats 27+ DSPs for those of you at home counting)
No, but it does apply a signal dependent dynamic eq. Protools will easily do the same kind off processing an X-fi does.

If you want to know more about how x-fi does it read this, then creatives comments and finally Maxim's final response. It's not just a simple eq.

common knowledge that you cannot take a signal going through a system and improve it
Ofcourse you can, our audio engineer at work does it everyday.

There's no point in the crystalizer really when you can have a non-coloured great sound (for the soundcard) feel to the music by enabling 'Bit-Matched' playback and if you're using XP, using an ASIO to bypass XP's ****ty sound processing. It's only really maybe good for movies and stuff to enhance the sound. Also since there arn't many gamers who frequent Head-fi thus no gaming perspective, EAX is only useful in gaming. That's it. That's it's purpose. Game programmers gripe about it a bit as it's in fact a b*tch to code for. There actually do prefer others such as OpenAL (used in a lot of 'independent' and freeware games) but majority and adoption rules!

Crystalizer is terrible.

but it can add more effects/processing to stereo sources, imho it made Bioshock a 2-3x better experience, and don't get me started on HL2 Ep2

thanks for the read

With raw data, yes, but you cannot take, lets say, a CD that was mastered poorly, and make it sound like an audiophile recording, unless you remaster it from the original data, its simply impossible, there is no "plus" system, only "equals" and "minus" systems

imho crystalizer is a "minus" system

::edit
so, read his reply, basically creative is full of it (from what he's saying), and he's not saying anything against the original article, just in addition to it

post #27 of 46
Yup, everything soundwise is done by software in HL2 engine.
post #28 of 46
well then, its still amazing

shows how much I pay attention to games' settings, I tend to just set everything to the maximum allowable, and usually its EAX 4 AdvHD, so I just figured that was HL2's limits too

One of the best sounding EAX game series is Thief.

i use it with cheap and cheerful mp3's and for gaming. thats it. seems to do quite well at giving an artificial boost!
