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 DS card can support sample rates up to 192KHz (44.1K, 48K, 96K,
192KHz). Usually audio CDs and MP3 files are 44.1KHz; DVD-Video uses 48KHz;
DVD-Audio or other HD media may contain 96KHz or 192KHz 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 DS 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.
