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 192KHz (44.1K, 48K, 96K,
192KHz). Usually audio CDs and MP3 les are 44.1KHz; DVD-Video uses 48KHz;
DVD-Audio or other HD media may contain 96KHz or 192KHz high-denition
audio content. Please select the corresponding sample rate for your playback
sources to get the best audio delity. Even if your setting differs from the audio
source’s sample rate, the Xonar D1 engine will do super high delity sample-rate-
conversion with a double oating-point lter, which can reduce total harmonic
distortion (THD+N) by -140dB.
