The KSDS3D_ITD_PARAMS_MSG structure specifies the parameters used by the interaural time delay (ITD) algorithm in a 3D node (KSNODETYPE_3D_EFFECTS).
EnabledSpecifies whether to enable the ITD algorithm. A nonzero value enables the algorithm. Zero disables it. For more information, see the following Remarks section.
LeftParamsSpecifies the ITD parameters for the left channel (channel 0). This parameter is a structure of type KSDS3D_ITD_PARAMS.
RightParamsSpecifies the ITD parameters for the right channel (channel 1). This parameter is a structure of type KSDS3D_ITD_PARAMS.
ReservedReserved. Set to zero.
This structure is used by the KSPROPERTY_ITD3D_PARAMS property request.
The Enabled parameter should track the DirectSound buffer's 3D mode: Disable ITD processing when the 3D mode is disabled, and enable it when the 3D mode is enabled. For more information, see the description of the DirectSound3DBuffer::SetMode method in the Microsoft Windows SDK documentation.
