Behavior At 24 Bits / 48 KHz

With 24-bit quantification and a sampling rate of 48 kHz, the card begins to show what it can really do. These settings are an especially good compromise between performance and reasonable file size. As a matter of fact, they're frequently used in professional applications. Dynamics and signal-to-noise ratio naturally jump much higher.

Frequency response (20 Hz - 20 kHz): +0.01, -0.19 dB
Weighted signal-to-noise ratio: 112.6 dB(A)
Distortion: 0.0005%
Stereo separation: 101.2 dB


Frequency response: The frequency response widens very slightly at the top and is obviously still perfectly linear...


Noise level: 24-bit quantification shows the card's limits, with an extremely low noise level


Dynamic range: Dynamic capacity reached the maximum value possible given the other parameters!


Distortion: Distortion as such is on the same order as what we observed at 44 kHz. The lower noise level is what explains the difference in the figures (THD+N).


Intermodulation distortion: Values are still infinitesimal and there's no danger of distortion being audible


Stereo separation: There was a (relative) increase in stereo crosstalk in the upper part of the spectrum, but it's off the graph, below 1 kHz...
