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-denition 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.
