CMI8738
PCI-6CH C3DX series /PCI-Based HRTF 3D Extension Positional Audio Chip
DESCRIPTION
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.
CMI8738 uses HRTF 3D extension technology to
enhance traditional HRTF 3D positional audio by
substituting two-speaker system by four or six -
speaker one.
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.
