CMI-8738/PCI-SX AUDIO Specification
1
Ver. 1.2
With high speed PCI V2.1 bus controller and legacy audio
SB16 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 – SB16, FM
emulator/DLS wavetable music synthesis, and HRTF 3D
positional audio functions.
Being compatible with A3D and DirectSound 3D, CMI8738
meets PC99
requirements
CMI8738 uses HRTF 3D extension technology to enhance
traditional HRTF 3D positional audio by substituting two-speaker
system by four- speaker one (it supports additional 2CH 16-bit
DAC to provide rear side audio). 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.
Being outstanding for its full audio functions, competitive price,
and power management, CMI-8738 is the best choice for people
seeking for optimum use of the PC applications.

Lab (CRL
), U.K, who provides one of the world's best HRTF
libraries
