m_dw3DMode

Specifies the 3D mode used. Can be one of the following values:

3D Mode	Description
BASS_3DMODE_NORMAL	Normal 3D mode.
BASS_3DMODE_RELATIVE	The 3D position is relative to the listener. If the listener position is changed, the sound position isn't changed
BASS_3DMODE_OFF	Will turn off 3D processing. Play will continue in the center.

These values are defined in the include file DemoGL_Bass.h.

m_fMinimalDistance

Specifies the minimal distance between the global listener and the sound channel. The channel's volume stops increasing when the global listener is within m_fMinimalDistance units from the sound channel.

m_fMaximalDistance

Specifies the maximum distance between the global listener and the sound channel. The channel's volume stops decreasing when the global listener is within m_fMaximumDistance units from the sound channel.

m_iInsideProjectionConeAngle

Specifies the angle of the inside projection cone in degrees. Legal values have to fall in the range [0,360], with 0 is no cone and 360 is a sphere.

m_iOutsideProjectionConeAngle

Specifies the angle of the outside projection cone in degrees. Legal values have to fall in the range [0,360], with 0 is no cone and 360 is a sphere.

m_iDeltaVolumeOutsideOuterProjectionCone

Specifies the delta-volume outside the outer projection cone. Legal values have to fall in the range [0,100], with 0 is silent and 100 is the same as inside the cone.
