IDirectSound3DBuffer8::GetConeAngles Method
[The feature associated with this page, DirectSound, is a legacy feature. It has been superseded by WASAPI and Audio Graphs. Media Casting have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Media Casting instead of DirectSound, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The GetConeAngles method retrieves the inside and outside angles of the sound projection cone.
Syntax
HRESULT GetConeAngles(
LPDWORD pdwInsideConeAngle,
LPDWORD pdwOutsideConeAngle
)
Parameters
- pdwInsideConeAngle
Addresses of a variable that receives the inside angle of the sound projection cone, in degrees. This is the angle within which the sound is at its normal volume. - pdwOutsideConeAngle
Addresses of a variable that receives the outside angle of the sound projection cone, in degrees. This is the angle outside of which the sound is at its outside volume.
Return Value
If the method succeeds, the return value is DS_OK. If the method fails, the return value may be DSERR_INVALIDPARAM.
Remarks
The minimum, maximum, and default cone angles are defined in Dsound.h as DS3D_MINCONEANGLE, DS3D_MAXCONEANGLE, and DS3D_DEFAULTCONEANGLE.
Requirements
Header: Declared in DSound.h.
Library: Use Dsound3d.dll.
