3D STEREO ENHANCEMENT
The WM8960 has a digital 3D enhancement option to artificially increase the separation between the
left and right channels. This effect can only be used for playback, not for record.
The 3D enhancement function is activated by the 3DEN bit, and the 3DDEPTH setting controls the
degree of stereo expansion. Additionally, one of four filter characteristics can be selected for the 3D
processing, using the 3DUC and 3DLC control bits.

3D Stereo Enhancement Enable
0 = Disabled
1 = Enabled
When 3D enhancement is enabled it may be necessary to attenuate the signal by 6dB to avoid
limiting. This is a user-selectable function, enabled by setting DACDIV2.
