Innovative VocalFX makes gaming and online chat more lively and attractive
VocalFX is an innovative voice processing technology to let your voice get into the realistic game landscape (VoiceEX) or to emulate the background scenes in online chat (ChatEX).

The noise on Xonar D1 audio card is only 1/35 (2.8%) of the noise level from most motherboard onboard audio. In addition, Xonar D1 also produces as little as 1/32 (-105dB) of the total harmonics distortion from motherboard audio does (-75dB).

S/PDIF header for combining audio with video through a VGA card's HDMI output
The new S/PDIF header allows connectivity with supporting VGA cards, facilitating merged output of audio and video through a VGA card's HDMI port. This provides a clean, simple solution for Home Theater PC builders.
