PCI-6CH C3DX series /PCI-Based HRTF 3D Extension Positional Audio Chip

9.5 HRTF 3D Extension Positional (C-Media 3DX)

3D illusion exists because traditional 3D positional audio system assumes the user's position as the sweet spot to

design crosstalk-cancellation circuit; therefore, if the user wants to have 3D positional audio effects, he can’t

move his head or position out of sweet spot. Another 3D illusion fails because half the population are

compulsive "head-turners" who will never get 3D audio from two speakers . To remedy this, C-Media utilizes

HRTF 3D extension technology (C3DX) to enhance traditional HRTF 3D positional audio by substituting

two-speaker system by four-speaker one. Therefore, at least one or two speakers should be placed behind the

listener's head to complement the rear-side effect, thus creating compelling realistic sound. This technology

greatly improves HRTF 3D positional audio quality, and successfully eliminates the sweet spot limitation. Users

can enjoy the real 3D audio gaming effects, and don't have to worry about the environmental confinement any

more.
