ASUS Xonar D1 

6.2 

Main Setting

6.2.1  Sample Rate

The Sample rate determines the number of audio samples per second that the 
Digital-to-Analog Converters (DAC) and S/PDIF digital interface will output. The 
Xonar D1 audio card can support sample rates up to 19KHz (44.1K, 48K, 96K, 
19KHz). Usually audio CDs and MP files are 44.1KHz; DVD-Video uses 48KHz; 
DVD-Audio or other HD media may contain 96KHz or 19KHz high-definition 
audio content. Please select the corresponding sample rate for your playback 
sources to get the best audio fidelity. Even if your setting differs from the audio 
source’s sample rate, the Xonar D1 engine will do super high fidelity sample-rate-
conversion with a double floating-point filter, which can reduce total harmonic 
distortion (THD+N) by -140dB.
