Behavior At 24 Bits/48 KHz

Moving to 48 kHz, and above to 24 bits, performance improved, as is to be expected. However the signal-to-noise ratio can be considered only average for a 24 bit sound card, though it's very good in absolute terms.

Frequency response : The variations were much slighter than at 44 kHz, and response extended higher. The entire audible spectrum was reproduced with a very low error rate.

;

Noise level : Noise was low and showed the same nice linearity as at 44 kHz.

Dynamic range : Nothing to criticize here - performance was very good against the signal-to-noise ratio.

Distortion : Distortion was even lower than at 44 kHz - an excellent result and significantly better than what Creative claims.

Intermodulation distortion : Again, very low distortion.

Stereo separation : Logically, stereo separation was identical to the result for 44 kHz.
