6.2.2 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 HDAV .3 card can support sample rates up to 2KHz (44.K, 4K, 6K,
2KHz). Usually audio CDs and MP3 files are 44.KHz; DVD-Video uses 4KHz;
DVD-Audio or other HD media may contain 6KHz or 2KHz 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 HDAV .3 engine will do super high fidelity sample-rate-
conversion with a double floating-point filter, which can reduce total harmonic
distortion (THD+N) by -40dB.
