Quantitative Analysis: RMAA 24-bit / 96 kHz

The highest quality test we run puts the X-Fi clearly above its competitors. These are the settings that DVD-Audio will use, and musicians will also likely record at this bitrate.

We do see a bit less consistency in the X-Fi graph at this setting, but even if the graph doesn't look as clean as it could, the X-Fi shows better performance than all our other cards at every step along the way.

    I would really like to see performance numbers on the cheaper x-fi components.

    "Thread-Interleaved" could also mean simply multithreading, but on a single processor ("engine").

    Am I wrong in assuming that having high stereo crosstalk in the upper ranges is worse than having it in the lower ranges? If not then this X-fi is junk because that crosstalk is way too high.

    You're right: the whole idea behind a 5.1 setup. With most modern music however a lot of high frequencies aren't even panned in a distinctive direction.

    What's the resolution of the ADC? Is it the same for the various X-Fi cards available at the moment?

    Creative still hasn't got it right. The chip resamples all audio, just like the Audigy series. This is no good for musicians and amateurs that want to use it to record audio. If you set your audio software to record 24bit 96KHz, it will downsample to 16bit 48KHz, and then upsample output back to 96KHz. Cheaper audio cards from M-Audio can do true sampling faithfully. Why can't Creative get it right?

    Sorry, but I'm passing it up and sticking with M-Audio. I may lose a few FPS and not have EAX3, but true, faithful sampling is what I also need for recording. I don't just play games. Creative thinks audio cards are only good for games, not recording. I'm not wasting money to buy two different audio cards.

    What product do you refer to? X-Fi does not need to down- or upsample. Everybody has their preferences but being M-Audio advocate does not mean you do not have to read review of the product you are posting comments about. X-Fi's clock works at the speed of your choice. And if you WANT to use sample rate conversion this has been vastly improved. That is the only card on the market that does distortion-free SRC which is great if you want to mix sounds from sources recorded at differnet sampling rates. Are you musician? I wish you were because you are not in position to appreciate how much this card can help a recordist or sound engineer...
  • DerekWilson - Wednesday, August 31, 2005 - link

    dejerez is right -- you can set the card to internally sample everything at 96kHz.

    I'll also agree that mixing sources of different samplerates with no distortion and no conversion necessary is a nice thing. But locking samplerate is also important in the current landscape of audio software.
  • mindless1 - Thursday, September 1, 2005 - link

    I'm not so sure you're correct here. Setting it to "sample everything at 96Hz" may be exactly what causes the resampling that audiophiles want to avoid. Internal sampling rate is a variable any card could do with software alone, but I/O sampling rate is not.

    It also appears to have NO 44.1 crystal, meaning it can't even play back an audio CD properly without resampling it.
  • Somerset - Tuesday, September 6, 2005 - link

    You can set X-Fi to play back audio CDs at 44.1kHz without any resampling. In the Audio Creation mode, you can easily set the master clock to 44.1kHz if desired. On the other hand, resampling is no longer a negative with X-Fi as all audio test graphs clearly show that X-Fi's resampling produces a very clean signal. Resampling should no longer be considered a weakness of X-Fi.
