Overview

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.
