3D STEREO ENHANCEMENT
The 3D stereo enhancement function artificially increases the separation between the left and right
channels by amplifying the (L-R) difference signal in the frequency range where the human ear is
sensitive to directionality. The programmable 3D depth setting controls the degree of stereo
expansion introduced by the function. Additionally, the upper and lower limits of the frequency range
used for 3D enhancement can be selected using the 3DFILT control bits.
