3D Control (22h)
Default: 0000h
This register is used to control the 3D stereo enhancement function, IDT Surround 3D (SS3D), built
into the AC'97 component. Note that register bits DP3-DP2 are used to control the separation ratios
in the 3D control for LINE_OUT. SS3D provides for a wider soundstage extending beyond the nor-
mal 2-speaker arrangement. Note that the 3D bit in the general purpose register (20h) must be set to
1 to enable SS3D functionality to allow the bits in 22h to take effect.
The three separation ratios are implemented. The separation ratio defines a series of equations that
determine the amount of depth difference (High, Medium, and Low) perceived during two-channel
playback. The ratios provide for options to narrow or widen the soundstage.
