Microsoft DirectX 9.0


The SetConeOutsideVolume method sets the volume of the sound outside the outside angle of the sound projection cone.


HRESULT SetConeOutsideVolume(
  LONG lConeOutsideVolume, 
  DWORD dwApply 



Cone outside volume, in hundredths of a decibel.


Value that specifies when the setting should be applied. This value must be one of the those shown in the following table.

Value Description
DS3D_DEFERRED Settings are not applied until the application calls the IDirectSound3DListener8::CommitDeferredSettings method. This allows the application to change several settings and generate a single recalculation.
DS3D_IMMEDIATE Settings are applied immediately, causing the system to recalculate the 3-D coordinates for all 3-D sound buffers.

Return Values

If the method succeeds, the return value is DS_OK.

If the method fails, the return value may be DSERR_INVALIDPARAM.


Volume levels are represented by attenuation. Allowable values are between DSBVOLUME_MAX (no attenuation) and DSBVOLUME_MIN (silence). The default value is DS3D_DEFAULTCONEOUTSIDEVOLUME (no attenuation). These values are defined in Dsound.h. DirectSound does not support amplification.
