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 Essence STX 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 Essence STX 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.
