CMI-8738/PCI-SX AUDIO Specification
Ver. 1.2
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.
