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 DX audio card can support sample rates up to 92KHz (44.K, 4K, 96K,
92KHz). Usually audio CDs and MP3 files are 44.KHz; DVD-Video uses 4KHz;
DVD-Audio or other HD media may contain 96KHz or 92KHz 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 DX engine will do super high fidelity sample-rate-
conversion with a double floating-point filter, which can reduce total harmonic
distortion (THD+N) by -40dB.
