CONST_DS3DMODEFLAGS

The CONST_DS3DMODEFLAGS enumeration is used by the DirectSound3DBuffer.GetMode and DirectSound3DBuffer.SetMode methods to set and retrieve the current operation mode for the 3-D sound processing.

Enum CONST_DS3DMODEFLAGS
    DS3DMODE_DISABLE      = 2
    DS3DMODE_HEADRELATIVE = 1
    DS3DMODE_NORMAL       = 0
End Enum
DS3DMODE_DISABLE
Processing of 3-D sound is disabled. The sound seems to originate from the center of the listener's head.
DS3DMODE_HEADRELATIVE
Sound parameters (position, velocity, and orientation) are relative to the listener's parameters. In this mode, the absolute parameters of the sound are updated automatically as the listener's parameters change, so that the relative parameters remain constant.
DS3DMODE_NORMAL
Normal processing. This is the default mode.
