Creative's X-Fi Audio Chip Reviewed 336

theraindog writes "The Tech Report has posted an in-depth review of Creative's new X-Fi audio processor. The 51-million transistor chip employs a unique audio ring architecture that pushes an apparent 10,000 MIPS, supports up to 128 hardware-accelerated voices for 3D audio, and can upsample and upmix stereo 16-bit/44.1kHz audio to multichannel 24-bit/96kHz. Creative says that the X-Fi's upsampling and upmixing capabilities can make MP3s sound better than the original CD, and although that claim isn't validated by listening tests, the X-Fi does sound better than other consumer-level audio cards. It also performs better in games, in part because precious few sound cards feature hardware acceleration for 3D audio."

      The _usage_ of the "MIPS" here might be mostly marketing bullshit (as it doesnt make the sound "better"), its not compareable to PMPO or co.

      Its just a bit decieving, because getting mips in audio chips is _REALLY_ easy. You are mostly dealing with 16 or 24bit integer values, in neat streams. You can build a whole function unit for a few 1000 transistors...

      So just give the thing 50 adders, 50 mul-units, runn it at 100 Mhz and you get 10 billion possible instruction per second (which might be burned quite quickly if you want to do bigger effects on xx streams, but thats another matter).

        I always had bad experiences with stable machines becoming unstable after installing Creative's drivers, and never liked that you can't seem to just install what seems like a driver but have to screw up your system with what seems more like an application suite / (buggy) driver combo.

      Exactly. The statement might be revised to "Precious few sound cards feature full hardware acceleration for 3D audio", since some cards like the SB Live! do 3D acceleration, just not on enough 3D channels to cover it all in hardware.

      This used to be a big issue in games where 3D (surround) sound was used. These days with faster processors, it isn't such a big issue any more. In fact, many modern games (Half-Life 2's Source engine, and DooM 3) both do all sound processing exclusively in software (though Creative later blackmailed Id into adding hardware support for DooM 3). It was decided for this current generation of games that CPUs were fast enough to do the sound processing in hardware, and that it was the best way to provide a consistent presentation no matter what sound card is used. Both games do all their 3D mixing, and their post-processing (reverb for example) entirely in software.

      Does doing it in hardware still provide a CPU benefit? Yes. Is it that important anymore? No, unless you're going nuts for framerates.

      I seem to recall a benchmark done years ago on an Athlon 1.4 that showed 40% CPU usage exclusively for 3D sound on the SB-Live, and something like 5% on the Audigy. Now, with current high-end CPUs at something like 3x faster than that, spending 15% of a game's CPU budget on sound is fine. Multithreading in games (to support multicore processors) will further reduce this, since you'll be able to offload sound processing to the second core.

Of course, X-Fi can't do this, so it must be "guessing" what the original information was.

      That image technology has been around forever. Just watch an episode of CSI.

      I was going to make much the same observation and then something occured to me:

      Quality of sound is subjective.

      It's why every crappy CD player and walkman comes with a Bass Boost. Boosting the bass doesn't make the sound more authentic than the original but, for the average listener with no idea what clear music should sound like, more bass is appealing and a selling gimmick.

      Similarly, you upsample, apply smoothing algorithms, apply fractal algorithms, whatever, you may be able to give a perception of clarity, of spacial separation, etc. far in excess of what the original CD had. That doesn't mean it's what the artist and engineers intended, it doesn't mean it's more accurate to the original performance, but you'll still get the average 13 year old telling you that Britney's latest masterpiece sounds even better now.

      So, you can make a track sound "better" to an average sampling of listeners without it being more accurate to the environment of the original recording. It's all about their definition of better.
      • It's also entirely possible to "upsample" a recording to make it more accurately represent the original - if you have out-of-band information. For instance, we "know" what a violin is, and that a violin doesn't make high frequency "popping" noises. So given a sample of a violin with popping, we can use noise reduction on it. The result will not only sound better subjectively, but be closer to the original sound source than the recording from which we're working! Does this violate some rule of informati

      I think my subject line is more appropropriate than yours.

      If there's one hardware firm I despise over any other then it's Craptive for that very reason. Aureal had some superb tech waiting to be unleashed. A3D 2 was superb and was easily a 10 frag head start in Q3 and HL, you could hear exactly where your enemy was and where they were coming from. A3D 3 was going to be even better until Craptive decided to bury Aureal in litigation. Then the vultures bought what was left of them and A3D lies in their vaults while they palm off their inferior reverb engine that is EAX.

      I still take out my Vortex 2 card and cradle it thinking of what could have been. Now I can only dream of Creative going under and someone like Nvidia and the ex-Aureal engineers they employed for SoundStorm finally bringing us true positional 3D audio.

      I don't care how good their latest chip is, creative can fucking rot in hell for all I care.

    • " Those fuckers killed Aureal. Creative has been on my shit list ever since..."

      And Aureal's strategy was to put Creative out of business. They were not a non-profit, nor would they have been satisfied with 50% of the market. This is competition.

        So fair competition in your eyes involves malicious litigation knowing that the legal burden will drive your much smaller competititor under?

        The only real audio card maker to have the balls to stand up to Creative was Diamond (remember them?). All the others wouldn't touch Aureal's tech while there was question marks over the legitimacy of Creative's claims which meant Aureal lost even more money. Later the courts would throw out every one of Creative's claims but by then it was too late.

        The real injustice was the fact that Creative after losing the court case was allowed to pick over the remains of Aureal and acquire their IP. There is something seriously wrong with capitalism when companies are allowed to do this. Whatever the outcome, Creative was going to end up the winner while you, I and Aureal were most definitely the losers.

I still have my MX300 in a drawer, on the off chance that someone with a soul gets an internship at Creative and leaks the driver source so that it can be updated for XP and Linux 2.6.

    So how does this compare to other sound cards? I've been told by others into pro-audio that the Audigy was an expensive over-hyped POS and sounds really bad compared to pro cards.

    So how does this compare to low end prosumer cards like M-Audio and Emu? Or higher end more professional cards from RME, Apogee, Lynx Audio? Or is this really pointless? If there is DSP accelleration on this new card, I was wondering if it could have pro applications like VST reverb or something along those lines.

      Basically all pro cards from the low end up are designed to do one thing only: get audio in and out of the computer accurately. You pay for more ins and outs, better converters, etc, but all they do is play and record sound.

      The Creative cards from the Live on up are all DSPs. They are designed to convolute sound. So in a game if they want it to sound like you are in a parking garage, they give the proper commands to the card and it convolutes the sound to do it's best appromation of a parking garage. This leads to both lower CPU usage and more realistic sound than doing the processing all on the CPU.

      So the problem is, because of this consumer focus, sacrafices were made. One was that the Lives and Audigys output (and input) only one sample rate: 48kHz (Audigy 2s have 96kHz, but only in special cases). They'll accept any you like under that, but sample rate convert that. They do an ok job, but not great, distortion is introduced that you can see on a scope and hear on good equipment. So they are right out for good recording. Also, they kinda chepskated on the converters for the cards, so they are noisy, compared to others in their price range.

      But, for all that, they are real, no-shit, DSPs. If you get the OSS kX drivers (http://kxproject.lugosoft.com/index.php?skip=1 [lugosoft.com]) you can actually write your own assembly programs for the DSP and control what it does.

      Now the X-Fi is extremely exciting as it fixes most of the problems people had. For one it has three different modes it can be set in. In pro mode it dispenses with all teh resampling crap and does accurate 1:1 bit capture at any sample rate up to 96kHz. In other modes where it does resample, it does it with a kickass high-order filter that introduces essentially no distortion.

      I am unsure if it has the ability to function as a VST plugin built in, but certinaly nothing precludes it from doing so. It's a powerful DSP and has the capability to route sound in and out of it.

      So, really, it's not comparable to pro cards. They are designed to do different things mostly. There are some pro cards that feature DSPs, but very few. These days in pro work, the effect processing is done in software. It's more flexable and real time is non-critical. However in a game, you can't dump 20% of your CPU in to doing a single high-quality reverb, so having a DSP is a real boon.

      Personally, I use both. I have an M-Audio Firewire 410 for pro, an Audigy 2 for consumer. I imagine that'll become an X-fi very soon here.

    WRT making audio sound better than the specs of the original file, the Gravis Ultrasound [wikipedia.org] cards claimed a similar feature. IIRC, they claimed to interpolate new samples between those fed into the card from, say, a .wav file. This card was from an era before MP3's were ubiquitous.

    From the The Official Gravis Ultrasound Programmer's Encyclopedia [gamedev.net]:
    ... it will interpolate the data to give an effective 44khz (or less, depending on how many active voices) sample. This means that an 8khz sample will sound better on the GUS than most other cards, since the GUS will play it at 44khz!

    I don't know if this was ever proven to be effective. Some people said that interpolation made lesser quality files sound "smoother". These same folks might also have had a lot of ink [snopes.com] on their hands...
    • The only thing I really remember about the GUS was all of the flamewares between GUS users and SoundBlaster users in the comp.sys.ibm.hardware.soundcards (or very much like that) Usenet newsgroup. It was a pathetic screaming match between entrenched camps of brand-obsessive nerds.

      Sadly, while that particular skirmish is long dead, the endless tribal nerdfights continue to this day.

    That line about MP3s sounding better at 96kHz is a bunch of marketing BS.

    There are reasons for 24bit/96kHz, but upsampling just to play it out of a speaker isn't one of them. That's kind of like printing out something at 2400dpi only to scan it back in again at 300. At best, you're going to wind up with exactly the same thing, while at worst you're going to have a bunch of aliasing artifacts from the upsampling.

    Upsampling for playback is worthless even if your source material is perfect CD audio. Taking something even worse than that (MP3) and upsampling it is just turd polishing.

    Want better sound? Buy better speakers. And a sound card that has high-quality analog components. The digitial part is not the weak part of computer sound playback. Hard to market that, though: "Now with 10db more S/N! And better capacitors!"

    24bit/96kHz is good for doing high quality recordings, then manipulating the sound and mixing it. Once that's done there's no point in distributing it in anything better than 16/44.1, if all that's ever done with it after that is playback. If you want your listeners to be able to do their own remixes, that may be another story, but then you have to distribute separate mixer tracks anyway...
    • At best, you're going to wind up with exactly the same thing, while at worst you're going to have a bunch of aliasing artifacts from the upsampling.

      You can't have aliasing from upsampling. Aliasing occurs from attempts to sample frequecnies that cycle at anything more than half the sampling rate. If you think about a wave, you have a peak and a trough. You need at least one sample on the peak and one on the trough to accurately represent that frequency. Any tone higher than one half of your sampling rate re

If you go from 44.1 to 48, or something that's not a multiple of your original sample rate, you have to interpolate a lot of the samples. And that's not a perfect process, because by definition you're guessing at what some of the samples should be.

        Yeah, so maybe it's not aliasing, technically. Maybe I should have said "artifacts". If you use a crappy interpolation algorithm (which I believe mass market sound chips have been known t

    For myself, and I know many others, the sound card is something you consider when building a new machine entirely. It is rare that something so good comes out that I feel compelled to upgrade the sound card. For me, when I build a new machine I get the new top of the line card then put my old one in my secondary work machine.

    As others have said, a good set of speakers is really more meaningful these days than the card. Yes, definitely the card can make a huge difference. But the difference between an Audigy 2 and an X-Fi? Not significant enough to warrant a new purchase unless it is a totally new machine.

    Which, by the way, I suspect that is where the majority of Creative's revenue comes from, Dell and others who buy their cards in large quantities for their higher end machines.

    "Creative says that the X-Fi's upsampling and upmixing capabilities can make MP3s sound better than the original CD"

    That's like saying you can make JPEG look better than the uncompressed image. Yes, you can improve the quality of MP3 by careful interpretation of data and perhaps extrapolating information for higher frequencies (which most often suffer from MP3 compression -- MP3Pro [mp3prozone.com] does something similar), but it will NEVER be as crisp and clear as the original material, let alone better.

    Not that you'll be able to hear the difference on your $20 desktop speakers you got at the 'Shack anyway.

Will this be 'better' like applying an unsharp-mask over a JPEG-compressed image which results in ugly squares?
