| PCI-Base HRTF
3D Extension Positional Audio Chip |
| With
high speed PCI V2.1 bus controller and legacy audio SBPro®
DSPemulator,CMI8738 is designed for PC add-in cards and all-in-one
motherboards. No external CODEC is needed in CMI8738: CMI-8738
supports the legacy audio – SBPRO™, FM
emulator/DLS
wavetable music synthesis, and HRTF 3D positional audio functions.
Drivers support
EAX®,
Karaoke
Key, Echo……functions.
Above all CMI8738 supports PCtel® HSP56 (1789)
interface.
Physical Chip
| Being
compatible with A3D™ and DirectSound™ 3D, CMI8738
meets PC99® requirements, and supports professional digital
audio interface such as 24-bit
SPDIF IN (0.5V ~ 5V)and OUT(44.1K and 48K format).
CMI8738
uses HRTF 3D extension technology to enhance traditional HRTF 3D
positional audio by substituting
two-speaker system by four or six - speaker one (it
supports additional 2 ch 16-bit DAC to provide rear side audio and
another 2 ch for subwoofer/Center).
It
greatly improves HRTF 3D positional audio quality and successfully
removes the sweet spot limitations: users can enjoy genuine 3D
audio gaming effects, and don't have to worry about the
environmental confinement any more.
