Main Setting
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 Essence ST 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-denition audio
content. 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 Essence ST engine will process super high delity sample-rate-
conversions with a double oating-point lter, which can reduce total harmonic
distortion (THD+N) by -140dB.
