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

Table 19 3D Stereo Enhancement Function

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.
