With the ASUS Xonar D1 PCI soundcard, users can enjoy the same rich gaming audio effects and extensive Dolby Home Theater features as the Xonar DX, and free up PCI express slots for other uses at the same time. This iteration of the Xonar provides fine-tuned audio components that reach a clear 116dB SNR (Signal-to-Noise Ratio), while the built-in DS3D GX revives support for DirectSound HW multi-channel gaming audio and the EAX (Environment Audio Extension) in PC games.
