KSDS3D_BUFFER_CONE_ANGLES structure

Description

A KSDS3D_BUFFER_CONE_ANGLES structure specifies the inside and outside cone angles.

Members

`InsideConeAngle`

Specifies the angle in degrees of the inside sound projection cone.

`OutsideConeAngle`

Specifies the angle in degrees of the outside sound projection cone.

Remarks

This structure is used to set or get the data value for the KSPROPERTY_DIRECTSOUND3DBUFFER_CONEANGLES property. DirectSound uses this property to implement the IDirectSound3DBuffer::GetConeAngles and IDirectSound3DBuffer::SetConeAngles methods, which are described in the Microsoft Windows SDK documentation.
