When you move to 24 bits, you're making full use of the card's capabilities, and so performance jumps. The cards clearly scored the best results we've ever measured on a consumer-oriented sound card, where noise is concerned, at any rate. The Audigy 4 is a success!

  • Frequency response (20 Hz - 20 kHz) : +0.09, -0.91 dB
  • Weighted signal-to-noise ratio : 108.1 dB(A)
  • Distortion : 0.0019 %
  • Stereo separation : 106 dB


Frequency response : A slight lack of linearity (of low amplitude) remained, but the result was very satisfactory.


Noise level : A record reading, in line with many professional sound cards


Dynamic range : The potential implied by the signal-to-noise ratio was realized!


Distortion : It came as no surprise that distortion is still very low and will be absolutely no problem.


Intermodulation : A very good result. No problems foreseeable.


Stereo separation : Stereo crosstalk was practically nil. You can't ask for much better.
