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.
