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.
|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.|
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.
