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 DSX card can support sample rates up to 192KHz (44.1K, 48K, 96K,
192KHz). Audio CDs and MP3 files are typically at 44.1KHz; DVD-Video uses
48KHz; DVD-Audio or other HD media may contain 96KHz or 192KHz high-
definition audio content. Select the corresponding sample rate for your playback
sources to get the best audio quality. Even if your setting differs from the audio
source’s sample rate, the Xonar DSX engine will execute super high-fidelity
sample-rate-conversion with a double floating-point filter, which can reduce total
harmonic distortion (THD+N) by -140dB.
