Selection of 3D for record or playback is controlled by register bit EQ3DMODE. Switching this bit from record to playback or from playback to record may only be done when both ADCs and both DACs are disabled. To enable the 3D Stereo Enhancement in the ADC path the device must be in 128fs mode by setting M128ENB to 1 in register R7 bit 8. Refer to the Low Power section under Power Management below for more details. The DEPTH3D setting controls the degree of stereo expansion. |
